Sulfide Ores an overview ScienceDirect Topics

Sulfide Ores. Sulphide ores were mostly created by (i) the intrusion of molten magma from the mantle into the crust of the earth and (ii) the formation of localized metal-rich sulphide ore bodies by sequential solidification and/or hydrothermal leaching and precipitation. From: Extractive Metallurgy of Nickel, Cobalt and Platinum Group Metals, 2011
