摘要

Wet treatment for the benefit of zinc and copper minerals in their compounds in the form of oxides and carbonates thereof, characterized in that once the ammonia cupro ammonia (copper tetramine) is obtained by dissolving the copper content of the mineral in water ammoniacal and filtered the liquid is placed in a deposit with zinc metal, thus producing the precipitation of the copper in the metal form and saturating the solution with the zinc hexamine compound that replaces the cemented copper in the solution.
