| Abstract: |
| For sulfide copper processing, besides some key ore genetic types, which could affect recovery rate of Cu, such as ore structure, occurrence of Cu, type of Cu minerals, it is also necessary to pay attention to other ore genetics associated with harmful elements, if content of harmful element high enough. For a high-As sulfide copper ore, most of As and Cu are both occurred in Enargite, and high-As copper minerals and no-As copper minerals are closed associated with each other, hence, it is hard to separated them with some physical process methods. Cu and As will concentrate in Cu-concentration with same concentrate ratio, and it is inevitable that arsenic exceeds standard in copper concentrate. |
