There is a broad range of TENORM concentrations in copper mining wastes. Mining and extraction of copper by surface or underground methods can concentrate and expose radionuclides in
Innovations How Hydrometallurgy and the SX/EW Copper
This solution, known as pregnant liquor, is recovered and then contacted with an organic solvent, referred to as the extractant, in the solvent extraction stage (SX). Here the copper is extracted away from the aqueous phase leaving behind most of the impurities that were in the leach solution.
Copper Mining and Processing Resources and Glossary
For copper oxide ore, solvent extraction is a stage in the process of hydrometallurgy, in which copper rich pregnant leach solution from the heap leaching stage is mixed vigorously with a solvent, allowing the copper to migrate into the solvent and be separated out.
