Hydrometallurgy—an environmentally sustainable technology?ast the difficulties, when hydrometallurgy is employed, of avoiding water pollution and the need to discharge solids which may be far from inert. A good example of this situation is that of jarosite, the main waste solid from the roast/leach/electrowin process commonly used for zinc recovery..Pyrome

Environmental impact of increasing production of gold from hydrothermal resourcesase so there is an upward trend in the exploitation of the so-called refractory zones associated with these deposits..These ores are pyritic in nature, often containing appreciable quantities of arsenic as arsenopyrite. Much of the gold is occluded in the crystal structure of the sulphide minerals,

Materials production and the environmente produced has in its transformation cycle, at least one extraction, processing, fabrication and manufacturing step in which releases of substances, gases, liquids, or solids, occur to the environment..This paper addresses some environmental problems associated with the extraction and processing of
