2015-6-22 The formation of Au enrichment zones relies on the solubilization and transport of Au. Gold concentrations of 10 to 500 ng L − 1 are common in ground-, soil- and surface waters, but concentrations of up to 35 μg L − 1 have also been reported (Boyle, 1979). However, we have little understanding of the fundamental processes of Auget price

able gold is dissolved in 14 days when manganese is present. It should be expected, then, that those auriferous deposits, the gangues of which contain manganese, would show the effects of the solution and migration of gold more clearly than non-man-ganiferous ores. Gold thus dissolved is quickly precipitated by ferrous sulphate.get price
