· In cyaniding ores containing copper minerals, it is found that the carbonate, oxide, and sulphate minerals particularly are attacked by cyanide with avidity, causing a heavy cyanide consumption by the formation of cuprosocyanide [KCu(CN)2]. In practice this is minimized by the use of extremely weak solutions. Provided that the copper content of the ore is not excessive, it is found that copper ...

obtained with coprecipitation of calcium and magnesium at recoveries of 43% and 13%, respectively. At pH>, % of the manganese was recovered, with coprecipitation of 97% of the calcium. According to Zhang et al. (2010) the precipitation of manganese carbonate is thermodynamically favoured over magnesium carbonate and (but to a lesser
ric acid and calcium as well as magnesium carbonate minerals (dolomite). Dolomite is a dominating gangue component of the Polish copper ores. This process, called either acid leaching or nonoxidative leaching, relies on treatment of the ore with lessthanstoichiometric amount of H 2SO4 required for a total decomposition of carbonates. The amount of sulfuric acid applied in the leaching ...
