Description

CROSS REFERENCE TO RELATED APPLICATIONS

This application is tied to a preceding Patent Pending Application (PPA) serial No. 60/207,429, filed May 30, 2000. A Patent Application has since been filed Mar. 6, 2001 and is awaiting review.[0001]

BACKGROUND

1. Field of Invention

This invention relates to precious metal extraction, specifically to the volatilization and recovery of precious, and other minerals using electromagnetic corona fields, induced by electricity or by other mechanical means, extracting precious metals and other minerals from solutions(s), slurries, and different typ(s) of, feed material(s) and in-place mineralized ground, by volatilizing them from these sources.

2. Description of Prior Art

Early inventors weren't aware of volatile metals existing in any quantities, therefore this area of mineral separation was overlooked. Although a few patents dealt with trying to volatilize stable metals, using plasma arc and lazar to melt or volatilize already stable metals. This invention covers an area that hasn't been covered, and the invention deals with the volatile aspect of high valance minerals separation in a non-polluting environmentally clean procedure. We can find no prior art that covers the essence of this invention, the exception is the PPA 60/207,429 and the corresponding patent application filed Mar. 6, 2001. U.S. Pat. No. 4,814,003; uses a lazar beam to volatilize precious metals from feed materials using extreme heat. The metals are either melted or volatilized, the metals are then collected and filtered off to be processed. Although laser beam technology can be utilized to volatilize and recover low valance precious metals, it is slow and expensive to operate. The cost is prohibitive as ore bodies get lower, and lower grade, and the cost of mining goes up and up. The mining operators have to run large tonnage to be cost effective. This process could not deal with high valance unstable precious metals liberated by the heat and could not be stabilized as metallic salt using this process. The Patent Pending Application (PPA) and the corresponding patent filed Mar. 6, 2001 deals with volatile metals, using air injection to volatilize them, removing these gasses with an air stream to a spray tower where they are separated from the air with sodium hydroxide. Although this is an efficient way to separate precious metals and other minerals. Sometimes in cases of the treatment of sewage and other volatile aqueous solutions and certain ores, the carry over of tramp minerals is quite large. It hampers the recovery of precious metals from large amounts of these contaminates.

DESCRIPTION OF THE PREFERRED EMBODIMENT

FIG. 1 Cut Away [0074]
Referring now to FIG. 1, a precious metal carrying solution enters the [0075] container 14, through the solution intake 32, the solution level 30 assumes the level of the solution trap 22, the solution 23 enters the intake 24 pipe in the bottom of the metal container 14. The solution 23 travels upward and exits through the solution outlet 34. The solution 23 is subjected to an electromagnetic field created by a energized electrode from an electrical source 28. The positive electrical conductor 12 goes to the metal container 14, and the insulated positive electrode 26 is wrapped tightly around the length of the metal container 14. The other end of the positive electrical conductor 12 where it leaves the metal container 14 goes to the air compressor 16 or other devices that would create a suitable electromagnetic field. The negative electrical conductor 10 goes directly from the electrical source 28 to the air compressor 16 or to other devices. Volatilizing gasses are drawn off the top of the tank by the inflowing air delivered by the air compressor 16 air line to the container 18, from other sources. The pregnant air is drawn off by the air line air line to recovery 36. This process could also be used with negative air pressure, using a vacuum to draw pregnant gases into the recovery circuit as in FIG. 3 and FIG. 4.
FIG. 2, Additional Embodiments [0076]
Certain volatile dry feed material minerals are susceptible to the external corona electromagnetic volatilization of precious metals and other minerals. Referring now to FIG. 2. [0077] Dry feed material 126 is fed into the metal container 128 through the chute 38 which in turn feeds the conveyer 124. The feed material 126 is subjected to a electromagnetic field that is induced by a positive electrode 114 wrapped around the container 130. The feed material 126 exits through the out let auger 132 or other suitable discharge devises. The feed material 126 now striped of minerals is ejected by outlet auger 132 or other suitable devices. The waste ends up in the stripped feed material 110 pile. The positive electrode 114 goes to the metal container 128 where the insulated positive electrode 114 is wrapped around the container 130. The positive electrode goes from the metal container 128 to the air compressor 118 or other devices where it energizes it and creates a electromagnetic field. The negative electrode 116 goes straight to the air compressor 118 or other devices. The air compressor 118 sends air down the air line to the container 117, where it sweeps the volatile gasses out through the air line to the recovery 122 unit. It could also be utilized with negative air, using a vacuum to draw the gases into recovery at in FIG. 3 and FIG. 4.
FIG. 3 Additional Embodiments [0078]
Certain mineralized material can be processed cheap and quickly by this exterior electromagnetic corona process. Now referring to FIG. 3, dry to [0079] moist feed material 212 is fed into chute, then fed down onto the belt of a conveyer 214 where the feed material 212 is exposed to the external electromagnetic corona effect of the wrapped rod or tube electrode 218. It is suspended above or under and lengthwise over the moving belt. Volatile gases are trapped by a hood 208 where they are drawn off and sent to recovery through suction line to compressor 216. From the electrical source 226, a positive electrode 224 is wrapped around wrapped rod or tube electrode 218, it terminates at the end of the wrapped rod or tube electrode 218 and is then wired into the compressor 220 or other devices to create an amperage load. The greater the amperage load, the greater the electromagnetic field. The greater the field the more diverse minerals will be volatilized and at greater distances. The negative electrode 222 goes directly to the compressor or other devises. The feed material 212 travels down the conveyor 214 and dumps off the end as stripped feed material 228.
FIG. 4 Additional Embodiments [0080]
Mineralized ground can be stripped of minerals in place using drilled holes in the surface of the ground. Now referring to FIG. 4, extracting minerals in place by drilling a [0081] bore hole 302 in the ground 318, and inserting a electromagnetic probe 304 into the bore hole 302. The electromagnetic probe 304 is energized by positive electrode 308. From there the positive electrode 308 goes to the compressor 312 or other suitable devices that will increase or control amperage. To increase or decrease the electromagnetic field as need be. The electromagnetic probe 304 when energized liberates volatile minerals which are trapped by the cone shaped cover 306 or by other suitable containment. The minerals are drawn off to recovery by the vacuum line to the compressor 310. The negative electrode 314 goes directly to the compressor 312 or other devices.
FIG. 1, FIG. 2, FIG. 3 and FIG. 4 Alternative Embodiments [0082]
There are also additional possibilities with regard to different types of magnetism. A.C. or D.C. voltage on a rheostat or some other devise to control the amount of current and the electro magnetic field intensity. Also the possibility of controlling the amount of volatility, selectively volatilizing certain minerals. Also electrostatic energy fields can achieve results volatilizing the volatile minerals in both FIG. 1, FIG. 2, FIG. 3 and FIG. 4 applications. [0083]
FIG. 2 Additional Alternative Embodiments [0084]
The added advantage of not crushing down to a fine consistency is an added factor. Electromagnetism releases volatile minerals while still locked up in rock the size of foot balls, making this process almost unique in its inception. In some cases not even needing a crusher feeding this dry system. Systems could be designed to hold feed material fragments up to several feet in diameter. It don't seem to make any difference what size the feed is, the electromagnetic field strips it of its precious metals in a matter of seconds. [0085]
FIG. 3 and FIG. 4 Additional Embodiments [0086]
The external corona field shown both in FIGS. 3 and 4 leads to exciting new innovative extraction using the continuous mining methods using the process shown in FIG. 3. FIG. 4 shows extraction of mineral in place using a bore hole. Holes could be drilled in a grid, to any depth and systematically extract minerals using the [0087] electromagnetic probe 304 and varying of amperage or voltage intensity to increase the electromagnetic field to over lap volatile mineral extraction between bore holes. Giving a whole new meaning to underground mining.
Advantages [0088]
From the description above, a number of advantages of the electromagnetic process becomes evident [0089]
(A) Providing a low cost extraction process to the minerals industry. [0090]
(B) Providing a clean, environmentally sound process to extract minerals. [0091]
(C) Provide a process for municipalities to use the air injection process on municipal water intakes and sewage and storm water to extract minerals and metals. The extraction process could offset the cost of providing water and sewer to the municipality. [0092]
(D) It would also provide an opportunity for conventional mineral extraction operations to use the electromagnetic process on their waste water to increase their profitability. [0093]
(E) Open up thousands of ore bodies and water sources to be utilized to produce precious metals or other minerals. [0094]
Operation—FIGS. 1 and 2 [0095]
The manor of using this process, the creating an electromagnetic field around a [0096] container 14. The electromagnetic field can be either Alternating Current, or Direct Current or it can be electrostatic current. Each of these cause a corona electric field surrounding the container. Now referring to FIG. 1: In which is fed a mineral rich solution 23 is fed into the metal container 14. The electromagnetic corona field is energized by a insulated positive electrical conductor 12 wrapped around the metal container 14. When energized, creates an electromagnetic field or corona. The positive electrical conductor 12 exits from the metal container 14 to the air compressor 16, or other suitable devises. The negative electrical conductor goes straight to the compressor or what ever devise energizes the electromagnetic field. The solution 23 is fed into the metal container 14 through the solution intake 32. The electromagnetic field volatilizes the precious metals and other minerals from the solutions 23. Low volume air from the air compressor 16 is swept across the top of the solution level 30 in the metal container 14 The volatile gasses are swept through the air line 18 to the recovery circuit. Now referring to FIG. 2: Ore or other feed material 126 is fed into the metal container 128 through the conveyer 124. The feed material 126 is subjected to a electromagnetic field, energized by a positive electrical conductor wrapped around the metal container 128. The positive electrical conductor goes from the metal container. It is used to energize the compressor 118 or what ever devise is used to produce the amperage amount necessary for the electromagnetic field. The precious metals and other minerals are volatilized to the top of the container and are swept out by a low volume of air. It may also be swept out by a vacuum, or negative air pressure rather than positive air pressure. In FIG. 2 it is delivered by the air compressor 118, through the air line to the container 117. The gasses are swept up into the air line to the recovery 122 circuit.
Operation of FIG. 3 and FIG. 4 [0097]
Now referring to FIG. 3, [0098] feed material 212 is fed into chute 210. Feed material 212 is fed down into the conveyor 214. The feed material 212 is stripped of its minerals as it passes underneath the energized wrapped rod or tube electrode 218. The wrapped rod or tube electrode 218 is energized by positive electrode 224. The stripped feed material 228 is discharged off the end of the conveyer 214. The volatile gases rise to the top of hood 208 and is drawn off by a vacuum from a suction line to the compressor 216 and to recovery. From the electrical source 226 the negative electrode 222 goes directly to the compressor 220.
Now referring to FIG. 4. A [0099] bore hole 302 is drilled into the ground 318 and a electromagnetic probe 304 is inserted into the bore hole 302. A suitable containment or cone shaped cover 306 is placed over the hole to catch the volatile gases. The gases are drawn off to recovery through negative air pressure through the vacuum line to the compressor 312. The process is energized by the positive electrode 308. The positive electrode 308 goes from the electromagnetic probe 304 to the compressor 312 or other devises that creates the amperages to create a sufficient electromagnetic field. The negative electrode 314 goes directly to the compressor 312. The volatile gases are drawn off to be processed.
The main embodiment of the present invention, shown in FIG. 1, FIG. 2, FIG. 3 and FIG. 4 has several advantages. For example, heavy metals are stripped from solutions and feed material in a environmentally clean manner. Leaving the solution and feed material cleaner, devoid of volatile minerals. It also opens up possibilities of cleaning up volatile heavy metals out of sewage, runoff or irrigation waters, municipal water supplies or possibly from super fund sites, or from other similar applications. [0100]
The effectiveness of the present technique for the extraction and recovery of precious metals and other volatile minerals, is further enhanced by the short retention time of the solutions, slurries and feed materials and stripping bore holes using the electromagnetic volatilization process. Letting the operator run larger volumes of solution, slurries or feed materials through the process in a short time. Or in the case of FIG. 4, large acreage amounts to the depth of the drill holes can be ran in a relative short time. The process is further enhanced by the cost of setting up the processing plant and processing the solutions or feed materials at a fraction of the cost of conventional processing. [0101]
