Abstract
A sulfur dioxide free process for the production of high purity metallic copper from copper matte wherein copper matte (11) is leached under oxidizing conditions in a ferric ion containing acid copper sulfate electrolyte leach assembly (2) including one or more leach reactors to yield a copper-rich electrolyte (13), and a copper cathode (41, 42, 43) is produced in an electrowinning assembly (4) which is physically decoupled from the leaching assembly (2) and may include one or more electrowinning cells. The process operates at ambient pressure and temperatures less than the boiling point.

1. A process for production of high purity metallic copper from copper-matte comprising the steps of: leaching copper-matte under oxidizing conditions in a ferric ion containing acid copper sulfate electrolyte leach assembly, including one or more leach reactors, to solubilize copper into a leach solution forming a copper-rich leach solution and a residue containing elemental sulfur; and electrowinning copper from the copper-rich leach solution and regenerating ferric ions in an electrowinning cell assembly, including one or more electrowinning cells; wherein the electrowinning cell assembly is physically decoupled from the leach assembly.
2. The process of claim 1 wherein the steps are carried out at atmospheric pressure.
3. The process of claim 1 wherein said steps are carried out at temperatures in the range of 40°C to the boiling point. 4. The process of claim 1 wherein the leaching is achieved by chemical attack of ferric ions.
5. The process of claim 1 wherein the step of leaching copper-matte is carried out under counter current flow of the copper matte and the leach solution.
6. The process of claim 1 wherein the electrowinning takes place in one or more electrowinning cells which do not contain a diaphragm.
7. The process of claim 1 wherein the current density in the electrowinning cell assembly is in the range of 500 to 2000 A/m2'
8. The process of claim 1 wherein the recirculation linear velocity of the electrolyte is in the range of 2 to 30 cm/sec. 9. The process of claim 1 wherein one or more of glue, thiourea, guar, and chloride are added to the electrowinning assembly.
10. The process of claim 1 wherein chloride is added to the leach tank assembly.

A process for the continuous production of high purity metallic copper from copper-matte comprising the steps of: preparing a finely divided copper-matte; leaching the copper-matte under oxidizing conditions in a ferric ion containing acid copper sulfate electrolyte leach assembly, including one or more leach reactors, to solubilize copper into a leach solution forming a copper-rich leach solution and a residue containing elemental sulfur; separating the copper-rich leach solution from the residue; electrowinning copper from the copper-rich leach solution and regenerating ferric ions in an electrowinning assembly including one or more electrowinning cells, wherein the electrowinning cell assembly is physically decoupled from the leach tank assembly; recovering from the electrowinning assembly an electrolyte rich in ferric ions; recovering elemental sulfur from the leach residue; and recovering precious metals from the leach residue.
15. The process of claim 14 wherein the leaching and the electrowinning steps are carried out at atmospheric pressure.
16. The process of claim 14 wherein the leaching and the electrowinning steps are carried out at temperatures in the range of 40°C to the boiling point.
17. The process of claim 14 wherein the leaching is achieved by chemical attack of ferric ions. 18. The process of claim 14 wherein the step of leaching copper-matte is carried out under counter current flow of the copper matte and the leach solution.
20. The process of claim 14 further comprising the steps of withdrawing a stream from the electrolyte rich in ferric ions and removing impurities from the stream, creating a purified electrolyte.
33
21. The process of claim 20 further comprising the step of transferring the purified electrolyte back to the electrowinning cell assembly.
22. The process of claim 20 wherein the impurities are removed through a process of solvent extraction. 23. The process of claim 20 wherein the impurities are removed through a process of ion-exchange.
24. The process of claim 20 wherein the removed impurities are one or more of As, Bi, and Sb.
25. The process of claim 14 wherein the electrowinning takes place in one or more electrowinning cells which do not contain a diaphragm.
26. The process of claim 14 wherein the current density in the electrowinning cell assembly is in the range of 500 to 2000 A/m2'
27. The process of claim 14 wherein the recirculation linear velocity of the electrolyte is in the range of 2 to 30 cm/sec. 28. The process of claim 14 wherein one or more of glue, thiourea, and chloride is added to the electrowinning assembly.
29. The process of claim 14 wherein chloride is added to the leach tank assembly.
30. A high purity copper cathode produced by the process of claim 14.
31. The high purity copper cathode product of claim 30 which meets the specifications for ASTM grade- 1.
