| titleOfInvention | A method for manufacturing high-quality sulfur sulfide by selective removal of iron in chalcopyrite |
| abstract | The present invention discloses a selective chlorination method using copper chloride (CuCl) to obtain high quality sulfide from chalcopyrite (CuFeS 2 ). In case of reacting copper chloride and chalcopyrite for 5 hours under an argon atmosphere after the addition of sulfur at 800 K to 1100 K using a quartz crucible, the iron was selectively removed from ferrochete into ferric chloride (FeCl 2 ) form. The mass% of iron was reduced from 31.5 mass% upon introduction to less than 0.05 mass% of the remainder. Therefore, high quality copper sulfide (Cu 2 S) was obtained in a single process from chalcopyrite. The iron removal rate reached 99.8%. Therefore, the selective chlorination method using copper chloride as a chlorinating agent can produce high quality sulfides from chalcopyrite. |
