Copper ore must be crushed between extraction and production. Crushing and grinding breaks down the ore from boulder-sized to smaller pieces, making it easier to transport off-site. After the ore is crushed, it undergoes concentration. This isn't necessary for some types of ore, such as oxide ores, as crushing and grinding are enough to ...

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.
