COPPER Copper production - Repository

The usual mode of operation is reducing smelting, which yields two main products. Sulfide ores are used to produce a matte (40 – 50 wt % Cu) and a disposal slag (ca. 0.5 wt % Cu). In contrast, oxide ores are processed directly to impure black copper( 95 wt % Cu) and to a copper-rich slag.

TENORM: Copper Mining and Production Wastes | Radiation

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. Uranium, which may be co-located with copper ore, may also be recovered as a side stream, if economical. However, in the United States this is not a general practice. L
