1. 41674/
2. WHAT WE CLAIM IS: A process for recovering copper, zinc or nickel from an ore containing such metal in the form of a sulfide mineral associated with iron sulfide, wherein the ore is treated by froth flotation to produce a primary sulfidic concentrate of said mineral together with associated iron sulfide, and leached with an aqueous solution conta4ning ammonium sulfate and free ammonia at a temperature in the range from 50°C. to 80°C. and at a pressure not exceeding 10 psig. in the presence of free oxygen, and the resultant pregnant leach solution is separated from the residual leached primary concentrates, characterized in that the leaching operation is terminated while a substantial amount*of undissolved copper, nickel or zinc remains in the residual leached primary concentrates, and said residual leached primary concentrates are subjected to a . flotation concentration operation .0 produce a secondary secondary/ concentrate substantially smaller in amount than the primary concentrate and to reject in the tailings of said secondary flotation operation iron sulfide of the primary concentrates which has been freed by the leaching operation from copper, nickel and zinc minerals. .- The process of claim 1 wherein the leaching operation is carried out y- vigorously agitating a slurry of the primary concentrates in the ammoniacal leach solution, characterized in that oxygen-bearing gas is continously recirculated throughout the leaching operation from above the surface of said slurry to a substantial depth below such surface. ·· ; ' ■ t 3.- The process of .either
3. The process according to claim 2 wherein the wash liquor from the washing operation is united with the leach solution for treatment to recover the dissolved metal .
4. A process according to any of the preceding claims wherein the undissolved solids after being separated from the leach solution and prior to the secondary flotation operation are subjected to releaching by being reslurried in aqueous ammonia-ammonium sulfate solution and by being vigorousl agitated in such slurry at a temperature from 60°C. to 90°C. and at a pressure not exceeding 10 psig. while vigorously recirculating free oxygen from above the surface of the slurry to a substantial depth below such surface.
5. The process according to any of the preceding . claims wherein the secondary sulfide concentrate is formed into a slurry in aqueous ammonia-ammonium sulfate solution and is releached by vigrjoously agitating such slurry at a temperature from 60°C. to 90°C. and at a pressure not exceeding 10 psig, while vigorously recirculating free oxygen from above the surface of the slurry to a substantial depth below such surface.
6. The process according to any of claims 1 to 4 wherein the secondary sulfide concentrate is smelted to recover its metal values.
7. The process according to any of the preceding claims in which the primary concentrate is a copper concentrate and contains in addition to copper other metal sulfide values > the primary concentrate, and said secondary concentrate is treated for the recovery of said other metal sulfide values.
8. The process according to claim 7, in which the primary concentrate contains a high proportion of copper sulfide minerals and a low proportion of molybdenite, wherein most of the copper sulfide minerals are dissolved in the course of the leaching operation, and substantially all the molybdenite is recovered in the secondary concentrate.
9. The process according to any of the preceding claims wherein primary concentrate is a copper concentrate and the aqueous leach solution is treated by a liquid ion exchanger dissolved in a liquid organic medium to extract the copper into the organic medium and to form an aqueous substantially copper-free raffinate containing ammonia and ammonium sulfate, the copper-loaded organic medium is treated with an aqueous sulfuric acid solution to recover the copper in the form of an acid copper sulfate solution and to regenerate the liquid ion exchanger, the raffinate is recycled for reuse in the leaching operations, and copper is electrowon from the acid copper sulfate solution.
10. The process according to claim 9 in which the primary concentrate contains zinc in addition to copper, and said zinc is dissolved in the leach solution and remains in the raffinate after liquid ion extraction of the copper, wherein at least a portion of the raffinate is treated to precipitate zinc as an insoluble compound therefrom, the precipitated zinc compound is separated from the residual solution, and the residual solution is treated for recovery of
11. The process according to claim 10 wherein at least a portion of the raffinate is treated with carbon dioxide under pressure to precipitate zinc in the form of an insoluble carbonate compound.
12. The process according to any of the preceding claims wherein the primary concentrate is a copper concentrate which comprises a substantial proportion of pyrite particles superficially coated with a copper sulfide mineral, such coating is dissolved in the leaching operation, and the resulting pyrite particles freed of such cupriferous coating are largely rejected in the tailings of the seconda COHEN ZEDEK & SPISBACH P.0.
