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.

Jan 15, 2019· Molybdenum ore flotation techniques are constantly challenged by the emergence of complex sulfide minerals, such as bismuthinite, in the mineral processing industry. Conventional flotation depressants, such as sodium sulfide, used in Mo–Bi-containing ore flotation require high dosages, which leads to high cost and low selectivity.

Copper extraction Wikipedia

As with oxide ores, solvent extraction and electrowinning technologies are used to recover the copper from the pregnant leach solution. Supergene sulfide ores rich in native copper minerals are refractory to treatment with sulfuric acid leaching on all practicable time scales, and the dense metal particles do not react with froth flotation media.

Mar 15, 2019· Secondly, the presence of pyrite in copper ores requires the use of lime in such a way as to avoid the flotation of this iron sulfide mineral. Previous studies show that calcium generates an effect that boosts the negative effect of clays in the flotation process of copper ores. This is an important difference compared to other applications.
