Internet Archive 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: Again, an ore may be treated by a system of concentration and 70 per cent, of the gold or silver "extracted.". Such an extraction is still further removed from actual recovery of metal or its equivalent money value. When the actual weight of the concentrate and the assay of the same are available for computation then the result may be The Metallurgy Of Silver Gold And Mercury In The United States Volume 2.
