Sulfide Minerals ThoughtCo

Galena forms in low- and medium-temperature ore veins, along with other sulfide minerals, carbonate minerals, and quartz. These can be found in igneous or sedimentary rocks. It often contains silver as an impurity, and silver is an important byproduct of the lead industry.

Converting Water into Gold WaterWorld

For gold miners, this creates a challenge because copper is soluble in cyanide, the chemical used to leach gold from the ore body. Presence of leachable copper in a gold ore body results in low gold recovery, and can increase cyanide consumption, increasing gold extraction costs and

Effect of Pretreatment of Sulfide Refractory Concentrate

For extraction of gold from refractory ores or concentrate, in which gold is surrounded or covered by iron sulfide minerals, mainly arsenopyrite and pyrite, mineral oxidative pretreatment is essential to oxidize sulfides and to expose gold to the leaching solution.
