CATALYZED DISSOLUTION OF COPPER FROM SULFUR-CONTAINING COPPER MINERALS

摘要

Leaching of copper from minerals containing sulfur and copper is hampered by the formation of sulfur on the surface of the mineral during conventional processing. An improved method for extracting copper from a sulfur-containing copper mineral is provided, comprising adding a lixiviant and a silica-containing or titanium-containing compound to a sulfur-containing copper mineral.
