The method of leaching metal sulfide with reagents with hydrogen sulfide functional group. （Divisional request 201902080）.

摘要

The invention relates to the use of a reagent with hydrogen sulfide functional group. The reagent can extract at least one base metal from the leaching solution containing sulfuric acid, which contains at least one oxidant, and at least one oxidant contains sulfuric acid. The hydrogen sulfide functional group in the reagent is concentrated in the range of 0.2 mm to 100 mm. In this range, the hydrogen sulfide functional group has a loaded sulfur,It has a negative potential surface and an empty U * as its unoccupied lower molecular orbital. In addition, it refers to a method of recovering at least one base metal from a sulfide base metal in one material.
