A Short History Of Hydrometallurgy Sciencedirect
200591ensp; ensp;modern hydrometallurgy, however, can be traced back to the end of the 19th century when two major operations were discovered: the cyanidation process for gold and silver extraction and the bayer process for bauxite treatment. later, in the 1940s, a breakthrough came during the manhattan project in usa in connection with uranium extraction.
Recovery Of Gold From Secondary Sourcesa Review

Gold Metallurgy And Leaching Process
2015624ensp; ensp;leaching, often gold, is the process of extracting a soluble constituent from a solid by means of a solvent. in extractive metallurgy, of gold, it is the process of dissolving a certain mineral (or minerals) from an ore or a concentrate, or dissolving certain constituents from materials such as a calcines, mattes, scrap alloys, anodic slimes, etc., to achieve either one or two purposes:.
