New approaches for extracting and recovering metals from

A two-stage mineral leaching and metal recovery protocol was developed to extract copper from tailings generated as waste materials in two mines currently operating in Spain and Serbia. The most effective extraction of copper (84 to >90%) was achieved by bioleaching the tailings at 45 °C, using a defined microbial consortium, where elemental

TENORM: Copper Mining and Production Wastes Radiation

Mining and Processing MethodsWaste GenerationDisposal and ReuseEPA and The StatesOres 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....

Copper extraction Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
