  • TENORM: Copper Mining and Production Wastes | US EPA

    Acids are introduced to copperbearing ore, seeping through and dissolving copper and any other metals, including radionuclides. The liquid that “leaches” through the rocks is collected. This liquid contains the dissolved copper, known as a pregnant leach solution (PLS). The copper present in this liquid is collected and later processed.
