After the pneumatic-gravity separation stage, within the method of the present invention, it is particularly preferred to include and collect the precipitated mineral precious gold seed sowing parts collected from them, and introduce these combined granular dumplings into use In the chemical-heat treatment stage of the plasma reactor device, which will be described in detail below, in which the merged fractions are separated by the plasma plasma to further separate the mineral heavy metals from impurities in impurities. This further processing stage results in the extraction of substantially pure mineral precious metals from the processed fraction. During the plasma phase separation stage of the method of the present invention, the mineral precious metal fraction in granular form is introduced into a reaction chamber of the plasma phase reactor. 1mm。 The average radial size of the precious metal particles to be treated should be less than about 0.1mm. Plasma gas flow is also introduced into the reaction chamber, and the gas is ionized to generate a plasma arc in the reaction zone formed in the reactor (between the cathode and the multi-node anode), where the temperature Rose to a level of about 10,000 ° K. The reactor was constructed and the order was determined in a way so that: causing the plasma arc to rotate rapidly around the segmented anode, and causing the granular fraction to undergo this action, therefore, causing these particles to The required spiral flow, through the plasma. In the preferred embodiment of the present invention, the limit used in the reactor includes: from 6 to 10 segments and most preferably 8-value segments, In order to obtain a plasma rotation that is preferably greater than approximately 15,000 revolutions per minute (RPM), and optimally, it is in the range of approximately 15,000-30,000 RP Μ.

Invention description (7) Furthermore, the plasma reactor of the present invention is constructed so that a rotating plasma arc is discharged between two fixed electrode structures. When a voltage of sufficient magnitude is applied across the electrode pair (ie: cathode and anode), a plasma arc discharge occurs. In an exemplary embodiment, the limit is a segmented annular ring, and each anode segment is electrically isolated from the others. Each anode segment is electrically connected to a constant potential plaque field, or grounded by a pair of solenoid coils arranged on either side of the Kumao segment at an angle of 90 °. The axis of each solenoid coil is parallel to a line drawn from the center of the reaction chamber to the anode segment connected to it. The plasma skull discharges from the cathode to a special Kuma pole segment and then to the ground, thus energizing a corresponding pair of solenoid coils. Therefore, the generated magnetic field tends to rotate the plasma arc to the adjacent anode segment. Then repeat this process, which results in a rapidly rotating plasma arc. Also, according to the present invention, a coaxial solenoid pipeline surrounds the perimeter of the reaction zone and is coaxial with the path from the cathode to the anode. The coaxial coil generates a second magnetic field to further increase the rotational speed of the plasma arc by changing the radial velocity of the plasma arc to a circular velocity.

At the same time, the remaining powdery and gaseous components are removed from the precious gold pendants required by the countercurrent flow of air and collected separately. Therefore, as a result of the chemical-thermal separation of the particulate matter using the plasma reactor of the present invention, a substantially pure mineral precious gold with a purity level exceeding 95% is extracted from the raw materials processed therein. In addition, based on its composition, the residual powdery and gaseous components that are separated from the collected precious gold can be further processed to produce other desirable substantially pure components. Alternatively, the collected residues can be used in some instances as valuable by-products of processing.

Construct the plasma grab 104 and make it suitable for introducing a suitable plasma skull gas, the purpose of which is to create a downwardly directed central plasma arc or gas flow 105 extending from the yin 106 to the position in the reaction chamber 110 (Downstream of the neck section 102) The multi-segment ring-shaped Yang-Yuan combination wine 108 The size of this paper uses the Chinese B home sample standard (CNS) A 4 specifications (210x297 ~ 27-A 6 B6 (please read the back Note: Please fill out this page), 01334 A 6 B6 Printed by the Central Consumer ’s Bureau of the Ministry of Economic Affairs Employee Consumer Cooperative V. Description of the invention (26). The plasma skull 102 has a channel 116 formed in it, which extends upwards and is distributed with the equipment Or the metering device (not shown in the figure) communicates to introduce the raw materials containing granular minerals into the reaction chamber 1 1 0. The one placed downstream of the reaction chamber 1 1 0 is a cylindrical cooling chamber 1 1 2 , It leads vertically downwards to the conical section 114, where the counter-current air is introduced through the inlet steam valve 138, the purpose of which is to pass some residual cooled material descending from the chamber 110 through the outlet steam valve 140 while blowing, as in the following Detailed description. During operation, once the particles are introduced into the chamber 110, they are contacted via the plasma arc 1 ~ 〇5, and the particles are heated to high temperature in an environment; in this environment, the plasma arc 105 For example, at a greater rate than what may be achieved using previous methods and devices, rotation or circulation is in progress, as shown by arrow A in Figures 7 and 8.

Thread-This paper uses the Chinese National Standard (CNS) A 4 specifications (210x297 mm) -28 ~ ^ 01334 A 6 B6 Plasma skull arc printed by the Pongong Consumer Cooperative of the Central Bureau of Economics of the Ministry of Economic Affairs 5. Invention Note (27). Anodes with sub-sections of up to 6 segments were previously in the United States Patent case No. 4, 361, 441 has been described, and it is incorporated herein for reference. In the device described in the patent case, according to the frequency at which the divided segments are activated, the activated anodes are intertwined The segment causes the arc to move in a circular manner at a rate of up to about 6,000 RPM. An electric exchange tool is used to perform entanglement activation of the anode segments. To assist in rotating the plasma skull arc, the '441 device of the patent also uses a rotating magnetic field. Due to the charged nature of the plasma, this magnetic field causes the arc to travel perpendicular to the force of the applied magnetic field and the speed of the arc. An array of solenoid coils arranged around the perimeter of the plasma arc path is used and continuously energized via an external source to generate a rotating magnetic field. As mentioned above, the present invention also uses a segmented anode 108. However, unlike the '441 device, the present invention does not use an electrically exchanged circuit system to cause the plasma arc to jump from one anode segment to another segment. Rather, as described in detail below, a magnetic field is used to rotate the plasma arc 105 from one anode segment to another segment, as described via arrow A. This means that the speed of rotation of the plasma arc does not depend on any frequency (at this frequency, the components of the electrical exchange can be activated). Therefore, it is possible to achieve a much larger rotation rate of up to about 30,000 RPM than is possible with these earlier devices. Referring to FIGS. 7 and 8, the segment-shaped anode 108 has a plurality of solenoid coils 120 arranged around its perimeter. Each coil 1 20 is wound around a low reluctance ring core 1 2 2 and its axis is oriented perpendicular to the axis of the reaction zone 118. In a preferred embodiment, the paper size is in accordance with the Chinese Standard (CNS) A 4 specification (210x297 g; «)-29-(please read the precautions on the back before filling out this page). 01334 A 6 B6 Printed by the Employee Consumer Cooperative of the Central Department of Economics of the Ministry of Economic Affairs 5. Description of Invention (28) Each anode segment has two such coils 120 and is positioned 90 ° on either side of the anode segment. Therefore, the total number of coils 120 is equal to twice the number of anode segments. Figures 7 and 8 show: the anode of 8 segments, and these segments are separated by insulating material 124. However, for simplicity, only four coils 120 are shown in FIG. 7, indicated by 120a, 120a ·, 120b, and 120b ·. The anode segment 108a is electrically connected to the coils 120a and 120a, and the anode segment 108b is electrically connected to the coils 120b and 120b. The coils 120a and 120b are wound in the opposite direction around the same portion 126 of the core 122. The coils 120a, 120b are wound similarly around the opposite core portion 122. Each coil 120 is also connected to an electrical ground, indicated by 130. Therefore, each anode segment is grounded in two ways to maintain it at a constant potential, where the insertion position is one of the solenoid coils 120 on the perimeter of the reaction zone 118 and oriented so that its longitudinal axis It is parallel to one (straight) line drawn from the center of the ring-shaped anode 108 to the holding anode segment connected to it. When the plasma mild arc discharge 105 occurs between the cathode 106 and a separate anode segment, current flows between the anode segment and the ground. Therefore, it energizes the two spirals associated with the segment Tube coils (eg, coils 120b and 120a). The purpose of the coil 120 is to generate a magnetic field oriented radially and directed toward (or away from) the anode segment conducting the plasma discharge. As shown in FIG. 7, the pair of coils 12a and 12b, which are arranged on opposite sides of the perimeter of the arc path, when energized, generates a radially oriented magnetic field vector Bi. Therefore, the magnetic field B; and (please read the precautions on the back before filling the nest page) The paper size is based on the Chinese Standard (CNS) A4 specification (210X297; ¢) -30--01334 Central Ministry of Economic Affairs A 6 _._ B6_ — printed by the Staff Cooperative of the Bureau of Standards — V. Description of the invention (29) B2 is at a right angle, causing the plasma arc 105 to pass a force in the circumferential direction. It is proportional to the axial velocity of the arc along the path from the cathode to the anode. Therefore, the operation of the plasma reactor 100 of the present invention is as follows: All anode segments are connected to the ground (or other constant potential) by a separate route, each including a solenoid coil 120. When the cathode is initially energized, a plasma discharge occurs between one of the cathode 106 and the anode segment 108 when the breakdown potential of the gas within the reaction chamber and the formation of a conductive plasma pathway are formed. If no other forces are present, the resulting plasma discharge will remain fixed, or randomly jump from the anode segment to another anode segment. However, the magnetic field Bi circumferentially forces the arc and causes it to jump to the adjacent anode segment. The anode segment sequentially energizes another pair of solenoid coils. This phenomenon additionally rotates the plasma arc to another adjacent cation segment. In this way, the plasma arc is entangled and rotated at a rate independent of the frequency of any electrical exchange. To grant even more angular velocity to the plasma arc, the present invention uses an additional solenoid 132 wrapped around the perimeter of the reaction zone 118 and coaxial with the axis of the reaction zone 118. Therefore, the coaxial solenoid 132, when energized by an external power source, causes an additional magnetic field B2 that is guided axially along the plasma arc arc path, as described in FIG. Therefore, field B2 causes any charged particle to move at a radial or circumferential velocity component, and a force guided by the component perpendicular to that velocity. The plasma skull arc is given a radial velocity component through each segment of the ring anode that is arranged close to the perimeter of the arc path, which is easy to cause the plasma to burn (please read the precautions on the back before filling this page).

Description of invention (30) The arc bends radially outward. Therefore, the magnetic field B2 transforms the linearly-directed linear momentum of the charged particles into angular momentum and rotates in an arc. In addition, the resulting circumferential velocity component of the rotating plasma arc (caused by the magnetic fields B2 and B2) acts on it via the field B *), which tends to draw the arc radially inward. This method provides the centripetal force necessary to maintain rapid rotation. Previous methods of granting angular momentum to the plasma arc, such as those shown in the previously cited patent 441, uniquely rely on the rotation of an external magnetic field that is rotated by means of electrical exchange, and the continuous activation of the anode segment is also via The tool of electrical exchange, which causes the plasma to rotate. This means that the plasma skull's angular velocity may not be greater than the frequency of electrical exchange. On the contrary, the present invention does not have this limitation and therefore, can grant a much larger rotational speed to the plasma arc. Therefore, when applying the method of the present invention, the precipitated granular fraction derived from the pneumatic-gravity separation of fly ash from atmospheric air or as a plasma gas is used to produce substantially pure T i 〇2. The temperature generated in the reaction chamber 1 1 0 of the plasma reactor 11 00 is about 10,000 ° K, and at a speed of about 16,000 RPM, the arc is rotated around the anode 108 of 8 segments Or turn. The particles are introduced into the top of the vertically aligned reactor chamber 1 1 0 through the channels 1 1 6 at a rate, so that: they descend spirally through the plasma arc. When the particles descend through the arc in the reaction chamber 110, the mineral precious metals (for example: A)? 2〇3 and T i 〇2) required by them melt, and the remaining components of the introduced particles, for example: Mg Or crystallize or steam (please read the precautions on the back before filling in this page) Pack · Line · This paper is used in the standard B a family standard (CNS) A 4 specifications (210x297 g *) -32-01334 A 6 B6 Economy Printed by the Ministry of Central Standards Bureau Beigong Consumer Cooperative V.

Therefore, when the processed materials are exported from the reaction chamber 110 through the anode 108, they enter the cylindrical cooling chamber 112, and when the molten mineral precious metals agglomerate into relatively dense particles, they descend through them With the temperature gradient, the crystallized residue forms powder particles, and the evaporated component forms gas. Therefore, when the resulting cooled components reach the lower section of the cooling chamber 112, they contact a value product guide or collector plate 134, which is placed centrally within the chamber 112, and its purpose is to cause: a fairly dense warp Agglomerated mineral precious metal particles, such as: Αβ2〇βΠΤ i 〇2, separated from other falling materials, in addition, plate 1 3 4, in a proper downward direction as a guide or guide the separation of precious minerals The gold particles pass through the tapered section 114 so that it can be collected on the bottom terminal 136 of the tapered section 114.

The better angle of the cone (angle Y ) Is about 30 °. However, as a result of the experiment, it has now been found that when dealing with raw materials having high concentrations of Fe and Cr, such as those derived from thin factories, the angle X should be Approximately 0 ° to approximately 37 ° and the angle Y should range from approximately 10 ° to approximately 30 °. For raw materials with a high concentration of Cu, Ni or Co, for example derived from the Mining 'or Hua plant, Angle X The range should be from about 5 ° to about 30 ° and the range of angle Y should be from about 15 ° to about 40 °. In terms of processing raw materials with high knots, such as those derived from sea sand, the angle The range of X should be about 0 ° to about 15 ° and the range of angle Y should be from about 30 ° to about 40 °. With regard to the raw materials with high concentrations of Ba 203 and Ti 〇2, the angle X The range should be from about 0 ° to about 30 °, and the range of the angle Y should be from about 20 ° to about 40,000.

Description of invention C34) The gas and the gas are distributed through the centrally placed tube or tunnel It is set at 154 and rises so as to contact the falling particles and guide the lower density material to the outlet steam valve 140, where they are exported through the outlet pipe 141 and are collected as a residue of the method of the present invention. In the preferred skeletal embodiment of the invention, the angle Z may range from about 35 ° to 60 °, and most preferably it should be about 45 °. However, if necessary, the angle Z can be changed in order to obtain the most suitable aerodynamic conditions within the conical section 114 to guide and guide the air introduced by the steam valve 138 in the form of direct air flow, or in the form of vortex, spiral The shape or rotation of the flowing air flow form to the outlet steam door 1 4 0. If necessary, a ventilating device (not shown in the figure) can be connected to the outlet pipe 141 to help collect the remaining material. The velocity of the air introduced into the conical section 114 is another important factor in considering the operation of the reactor 100 of the present invention. For example, it has now been found that, generally speaking, the air velocity introduced into the section 114 through the steam valve 138 should be in the range of about 1 to 20 m / sec. The rate of air is adjusted based on the density of the precious minerals extracted. For the heaviest or densest particles such as Fe_Cr, a higher rate is usually used, while for less dense materials, a lower rate is used. . For example, when the fly ash raw material particles are processed in the reactor, it has now been found that an air velocity of about 1.7 m / sec should be introduced into the conical section 114 through the steam valve 138. In addition, it has been found that for some applications of reactor 1◦0, it may be necessary to: set an electromagnet 1 5 6 chen shape to encapsulate the cylindrical cooling (please read the notes on the back before filling this page ) Installation-Line-This paper scale uses the Chinese S Jiamu standard (CNS) A 4 specifications (210X297 male dragon) -36-^ 01334 A 6 B6 V.
