TENORM: Copper Mining and Production Wastes | US EPA
Jun 07, 2021· When processing copper through heap leaching, vast quantities of ore and overburden overburdenSoil and rocks that have been moved out of the way to get to ore are called "overburden." In areas where there are high concentrations of radionuclides in the rock, overburden may have some enhanced radioactivity, but not enough to mine and process.

In addition to copper and gold, PT-FI produces silver. FCX has a 48.76 percent interest in PT-FI and manages its mining operations. PT-FI’s results are consolidated in FCX’s financial statements.
Copper | Geoscience Australia
The ore is then ground finely before the copper-bearing sulfide minerals are concentrated by a flotation process which separates the grains of ore mineral from the waste material, or gangue. Depending on the type of copper bearing minerals in the ore and the treatment processes used, the concentrate typically contains between 25 and 30% copper,
Mineral Processing - an overview | ScienceDirect Topics
Mineral processing, mineral beneficiation, or upgradation involves handling three primary types of ROM material, which have been blasted, fragmented, and brought out from an in situ position. These materials can be used directly or by simple or complex processing and even by applying extractive metallurgy like hydrometallurgical or pyrometallurgical methods.
