Hydrometallurgy science Britannica

Hydrometallurgy originated in the 16th century, but its principal development took place in the 20th century, stimulated partly by the desire to extract gold from low-grade ores. The development of ion exchange, solvent extraction, and other processes has led to an extremely broad range of applications of hydrometallurgy, now used to produce

Hydrometallurgy an overview ScienceDirect Topics

Hydrometallurgy refers to the application of aqueous solutions for metal recovery from ores, and has been practiced for copper recovery for many years. The original impetus for solution methods for copper extraction before the development of froth flotation technology was the existence of large ore bodies of low copper content which were

Hydrometallurgy of Gold Gold Industrial Processes

Hydrometallurgy of gold 67 Thiosulphate The first reported use of thiosulphate for precious metal extraction dates back to the beginning of the century. In that method, known as Pateras process, the ore was first roasted in a chloride atmosphere and just after a thiosulphate leaching was used to recover gold and silver (Zipperian et al. 1988).

What Is Hydrometallurgy? wiseGEEK

Hydrometallurgy is a process for recovering valuable metals dissolved in a water-based chemical mix containing metallic salt compounds. Such metal recovery usually is based upon sulfuric acid solutions and the metals that are targeted for recovery are either precious metals such as gold, platinum,and palladium,or more common industrial
