The separation of mineral from gangue is known as mineral processing mineral dressing or ore dressing It is a necessary and often significant aspect of mining It can be a complicated process depending on the nature of the minerals involved For example galena an ore of lead is usually found in large pieces within its gangue so it

The barren rock or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore By far the greatest proportion of copper is extracted from the sulfides of copper iron and sometimes other metals Such ores originate from sulfur-bearing volcanic magmas which have separated into metal sulfides and siliceous melts
