The chemical processing of ores to recover the metal values in pure form is commonly referred to as extractive metallurgy as presently practiced it is subdivided into hydrometallurgy and pyrometallurgy. Hydrometallurgy involves reacting the ore at low or moderate temperatures with a hquid solvent that will selectively dissolve the valuable metal or metals, separating the dissolved metals from each other by...

The different uses of liquid-liquid extraction, liquid membranes, and solvent impregnated materials make the subject important for university students of chemistry, metallurgy, hydrometallurgy, and chemical and mineral processing technology. Some universities offer special courses on separation processes in which those techniques are minor topics in more comprehensive courses. Laboratory experiments on liquid-liquid and liquid membranes are common in chemical and mineral processing engineering curricula. Because of the breadth of the subject, the treatment in such courses is often scarce, and more comprehensive text is difficult to find in a form suitable for use directly with students.
