Method for removing arsenic and antimony from copper ore concentrates |
| abstract |
Method for removing essentially all of the chemically bonded arsenic and antimony from copper sulfide ores. The arsenic and antimony are selectively leached out using Na2S in a basic solution. The resulting Na3AsS4 and Na3SbS4 are converted to the sulfides or to ferric arsenate and ferric antimonate for safe disposal. Sodium and sulfur values are recovered for recycling in the process. |
