C = F/K = F (f — t) / (c-t) = the weight of the concentrate. Recovery %. Represents the ratio of the weight of metal or mineral value recovered in the concentrate to of the same constituent in the heads or feed to the process, expressed as a percentage. It may be calculated in several different ways, depending on the data available.

The Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today's compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it's roasted, which helps to convert sulfides to oxides.

Copper ore beneficiation methods. Before the beneficiation of copper ores, crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm.

TENORM: Copper Mining and Production Wastes | US EPA

Ores that contain copper in the U.S. are typically mined in large, open-pits. Copper processing facilities are usually located near mining or extraction sites. Significant waste volumes are associated with copper production. Mine wastes may contain radionuclides due to their natural presence in ores and can be a source of TENORM.
