Method for recovering a copper sulfide from an ore containing an iron sulfide |
摘要 |
In a method for recovering a copper sulfide concentrate by froth flotation from an ore containing an iron sulfide, hydrogen peroxide is added to the conditioned mineral pulp before or during flotation, a concentration of dissolved oxygen is determined in the mineral pulp after addition of hydrogen peroxide and the amount of hydrogen peroxide added is adjusted to maintain a concentration of dissolved oxygen of from 1 to 5 times a predetermined target concentration, in order to adjust the amount of hydrogen peroxide to changes in ore composition. |
