Innovations: Introduction to Copper: Mining &

2021-1-21  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.

Ore, as mined, contains ore minerals, gangue minerals, and country rock. A mass of mineral matter is not considered ore unless one or more of its ore minerals can be recovered on a profitable basis. As originally used, ore minerals were metal bearing (see Metallic Minerals).More recently, nonmetallic minerals of commercial importance are considered ore minerals (see Mineral Industries).

2018-8-7  Copper grade is the concentration of copper in the ore rock. To calculate the grade of copper for the sample, geologists use the equation: (amount of copper metal/amount of copper ore rock)*100 2.
