Sulfide Ores: Characteristics and Economic Significance
Sulfide ores are ores in which minerals are found in chemical compounds with sulfur. Sulfide ores are of great importance in the mining and processing industry, as well as in metallurgy. The choice of ore enrichment method depends very much on the sulfur content of the rock. Sulfur is an impurity element in terms of obtaining pure metals and ...

How is Copper Extracted from Its Sulphide Ore (Copper …
Copper is extracted by heating its sulphide ore alone. Two steps involved in the extraction of copper metal from concentrated copper glance ore are: 1. Roasting: Copper glance, being a sulphide ore, is heated in the presence of air. Copper (I) sulphide is converted to copper (I) oxide. Copper (I) oxide, so formed, reacts with non-oxidised ...
