Solvent Extraction Glossary of Terms

Some of the more important technical terms used in this World Mining article and in other solvent extraction literature. Contactor Device for dispersing and disengaging immiscible solutions; extractor. May be single stage, as in a mixer-settler, or multiple stage, as in columns and certain centrifuges. Countercurrent extraction Multistage extraction in which the aqueous and organic solutions … Read more

SX Solvent Extraction Process Principles Theory

An increasing demand for metals in general, and higher purity metals in particular, decreasing ore grades and more stringent environmental regulations have driven, and will continue to drive, research into finding more effective and efficient methods for processing the ores available to us, and recycling previously used metals. Hydrometallurgy has provided, and will continue to … Read more

Solvent Extraction Plants: Thiele Diagram & Theoretical Design Aspects

It has been explained in an earlier talk that solvent extraction in the copper industry is used to convert impure, and frequently very dilute copper solutions into very pure and concentrated solutions from which pure copper can be extracted by a variety of means, usually electrochemical. These impure solutions emanate from in-situ leaching, dump leaching, … Read more

Solvent Extraction Process SX: Hydrometallurgical Extraction of Copper

In recent years, the principle and theory behind solvent extraction has gained wide acceptance as one of the new tools of modern hydro-metallurgy. With the growing demand for metals of ever higher purity, the increasing use of unusual metals, and the necessity for treating ores of lower grade and greater complexity, solvent extraction has joined the … Read more
