TENORM: Copper Mining and Production Wastes | US EPA

Solvent extraction. Once PLS is leached, it is sent to a solvent extraction plant to remove the copper. The PLS is mixed with an organic solvent that binds to the copper and chemically separates the copper from the rest of the liquid. Then, the copper-bearing liquid is combined with another acid to precipitate the copper from the organic material.

SX-EW (solvent extraction and electrowinning) | KGHM ...

SX-EW technology involves leaching (the process of dissolving useful ingredients with a solution) in atmospheric conditions of copper ore heaps by means of diluted sulphuric acid. Folowing leaching, the pregnant leaching solution is transported via a drainage system to the next stage. In an SX-EW reactor, the first process to take place is solvent extraction, which involves setting and ...

Solvent extraction | chemistry | Britannica.com

Solvent extraction combined with electrolytic deposition takes dilute, low-value metal solutions and concentrates them into small volumes and high metal contents, rendering them satisfactory for electrolytic treatment. Low-grade copper ores are processed in this manner.

What is Solvent Extraction? (with pictures) - wisegeek.com

Jun 17, 2019· Solvent extraction is a method for separating a substance from one or more others by using a solvent. It relies on variations in the solubilities of different compounds in different substances. In most cases, the substance to be extracted, which may be a solid, a liquid or a gas, is dissolved in a liquid, along with other substances, and a liquid solvent is used for the extraction — this is ...
