Influence of copper minerals on cyanide leaching of gold ...
In elucidating the influence of copper minerals on cyanide leaching of gold, copper minerals were classified into two types according to their solubility in cyanide solutions by proposing two concepts, cyaniding easily soluble copper (E Cu) and cyaniding insoluble copper. The former involves copper occurrence in metal, oxides and secondary ...

Leaching behavior of metals from iron tailings under ...
The leaching amounts of metals tended to decrease with increment of initial pH and leaching time, although some metal elements were also detected at alkaline conditions. Similar results were reported by Cappuyns and Swennen (2008). It is likely that iron phase precipitation occurs when the pH of a solution changes from acidic to neutral.

A process is provided for heap leaching ore to recover nickel. The process is particularly effective for ores that have a tangible clay component (, greater than about 10% by weight). The process includes sizing the ore (where necessary), forming pellets by contacting ore with a lixiviant and agglomerating. The pellets are formed into a heap and leached with sulfuric acid to extract the ...
