Therefore, the total number of coils 120 is equal to two Γ _____ | times the number I of anode segments. Figures 7 and 8 show that the anode T ~ of 8 segments is separated by the green 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 opposite directions around the same portion 126 of the core 122. The coils 120a '120b' are similarly wound around the opposite core portion 1 2 2. Each one-value coil 120 is also connected to electrical ground, indicated by 130. Therefore, each anode segment is grounded in two ways to maintain it at a constant potential, where the intervention position is on one of the solenoid coils 12 on the perimeter of the reaction zone 118 and is oriented so that its longitudinal The axis is parallel to one (straight) line drawn from the center of the ring anode 108 to the holding anode segment connected to it. When the plasma condyle arc discharge 105 occurs between the cathode 106 and a special anode segment, current flows between the anode segment and the ground, therefore, it energizes the two solenoid coils associated with the segment (For example: coils 120b and 120a).

It is proportional to the axial velocity of the arc along the path from the cathode to the anode. _....... .1 · '.III ----- ,, ||-〇 Therefore, the present invention The operation of the plasma waist reactor 100 is as follows: All anode segments are divided to ground ^ or other constant potentials, each of which includes a solenoid line 12o. When the trans-potential and the male-skeletal pathways such as conductivity are formed, the plasma discharge occurs between the cathode 10 06 and one of the anode segments 108. If there is no other force, the resulting plasma discharge will be maintained, or randomly, jump from the anode segment to the anode segment. However, the magnetic field B, which circumvents the forced arc and causes it to jump to the adjacent anode segment. I anode segment sequentially energizes another pair of solenoid coils. This phenomenon turns the plasma arc to another adjacent cation segment. In this way, the plasma arc is rotated continuously at any rate independent of the frequency of the electrical exchange. In order to confer even more angular velocity and plasma arc, the present invention uses an additional solenoid 132 that surrounds the perimeter of the reaction zone 118 and is coaxial with the axis of the reaction zone 118. Therefore, the coaxial solenoid 132, when pre-fed by an external power source, causes an axial guidance along the plasma arc path (magnetic field B, as described in FIG. 8.

Description of the invention (3〇) The body arc is bent radially outwards. Therefore, the magnetic field transition is guided by the radial direction of the engraved particles The linear momentum becomes the angular momentum, and the arc rotates. In addition, the resulting solar radiation velocity component of the rotating plasma arc (caused by the magnetic field and 32) acts on it through the field B *, and it is easy to pull the arc in the radial direction. Inward. This method provides the centripetal force necessary to maintain rapid rotation. The previous method of granting angular motion Dong and the plasma skull arc, such as shown in the '44 1 patent case cited previously, Tung relies on the rotation of an external magnetic field that is rotated by means of electrical exchange, and the connection of the anode segments The activation is also through the tool of electrical exchange, which causes the rotation of the plasma. This means that the angular velocity of the plasma may not be greater than the frequency of electrical exchange. On the contrary, the present invention does not have this limitation and therefore, it is possible to confer a much higher rotational speed to the plasma mild arc. I Therefore, in the application of the method of the present invention, the airborne or gravity of atmospheric air is used as the plasma gas from the pneumatic-gravity separation of the fly ash and the precipitated granular dumplings are derived to produce substantially pure A 3 and T i. The temperature generated in the reaction chamber 1 1 0 of the plasma skull reactor 100 is about 10, 000 ° K, and at a speed of about 16,600 RPM, causing the arc to wind around the anode of 8 segments 108 while rotating or turning. The particles are introduced through the channels 1 16 at a rate into the top of the vertically aligned reactor chamber 1 1 ◦, so that they descend spirally and pass through the plasma arc.

In addition, the plate 134 acts as a proper downward direction to guide or guide the separated precious metal particles through the cone Shaped section 114 so that it can collect on the bottom end 136 of the conical section 114. In section 114, the counter-current flow or vortex of air is directed upward from the inlet steam valve 138 to the outlet steam valve 140 in order to The powder particles and the gas accompanying the agglomerated minerals are separated from the condensate and blown out of the reactor through the outlet pipe or tube 141 associated with the outlet steam valve 140.

The preferred angle of the cone (angle Y) is about 30 °. However, as a result of the experiment, it has now been found that in terms of processing raw materials with high concentrations of Fe and Cr therein, such as those derived from self-binding factories, the angle X should be from about 0 ° to about 37 °. The vane of the angle Y should be from about 10 ° to about 30 °.

In terms of processing raw materials with high concentrations of knots, such as those derived from sea sand, the range of angle X should be about 0 ° to about 15 ° and the range of angle Y should be about 30 ° to about 40 °. For raw materials with a high concentration and Ti, the angle X should range from about 0 ° to about 30 °, and the angle Y should be from about 20 ° to about 40 °.

The height h »of any specific embodiment of the segment 1 14 can be calculated as a function of the cone angle Y using the following formula: hs = 1/2 d * (tangent Y) where , Ds is the diameter of the cone 1 14 on the horizontal top edge 148 of the segment 1 14. At this point, the diameter ds of the cone 1 14 can be calculated from the following additional formula: ds = 1.2 dr where, dr is the diameter of the cylindrical cooling chamber 112. Another important feature when constructing the reactor 100 is to supply a slap with an appropriate corner wall | the upper position is at the bottom edge 1 52 with the cylindrical cooling chamber 1 1 2 A horizontal line and a horizontal line with the top edge 148 of the tapered section 114. The wall 150 circumferentially interconnects and closes the chamber 112 and the tapered section 114.

Description of the invention (34) : Powdery particles and gaseous concoctions, ascending through the centrally placed tube or tunnel configuration 154 to catch the falling particles and guide the lower density materials to the outlet steam valve 140, where they exit through the outlet tube 141 and It is collected as a residue of the method of the present invention. / 1 \ (\ In the preferred skeletal embodiment of the present invention, the circumference can be from about 35 ° to 60 ° ^ the most suitable should be about 5. However, depending on If necessary, the angle Z can be changed to obtain the most suitable aerodynamic conditions Within the conical section 1 14 is used to guide and guide the air introduced at the steam valve 138 to the outlet steam valve 140 in the form of direct air flow or flowing air flow. If necessary, a ventilation device (Figure (Not shown in the figure) is associated with the outlet pipe 141 to assist in the collection of residual material. The speed of the air introduced into the conical section 114 is another important factor in the operation of the reactor 100 of the present invention. For example, it has now been found that, in general, the velocity of air introduced into section 1 14 through steam ^^ 3 ^ should be in the range of about 1 to \. The rate of air is adjusted based on the degree of minerals being 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 the reactor 100, it may be necessary to provide an electromagnet 156 to enclose the cylindrical cooling chamber in an annular shape.
