| Abstract: | The direct hydrogen reduction of Cu 2S in acidic and basic slurries are investi ga ted by the help of SEM and X-ray diffraction. The results show that the reduct io ns proceed to a certain extent in the two systems, but the reduction mechanisms may be probably different. The reduction of Cu sulfides tends to completion whe n proper amount of ZnO is added into the basic Cu 2S or CuS slurry, and the tran sformations of Cu reach to 92% and 85%, respectively. |
