Assuming that a gold ore has been effectively ground to ensure maximum economic liberation of gold, the circuits that will have the most effect on the successful operation of a gold plant will be that of the leaching and carboninpulp circuit (CIP). The reagent and utilities operating costs associated with leaching, adsorption, elution and ...
To those of us in the gold industry, the question "What is heap leaching?" seems to have an obvious answer. In the simplistic sense, heap leaching involves stacking of metalbearing ore into a heap on an impermeable pad, irrigating the ore for an extended period of time (weeks, months, or years) with a chemical solution to dissolve the soughtafter metals, and collecting the leachant ...
Oct 15, 2009· Leaching processes of metallic copper or ores containing copper in the divalent state have been the subject of many research works in recent years,,,, . However, no study was found concerning the dissolution kinetics of CuO/Al 2 O 3 catalyst in inorganic or organic acid solutions.
The research was conducted on lowgrade oxidized gold ores with application to heap, dump or in situ leaching techniques. The range of the thiosulfate concentration tested was – M. After leaching for 48 h, 83% gold extraction was achieved with M S 2 O 3 2− with kg S 2 O 3 2− consumed per ton of ore.
Download Citation on ResearchGate | Craft of washclassification of heap leaching used in highclay copper oxide ore | The factors which affect the permeability of highclay heap were analyzed.
The acid leaching of copper oxide ores generates a vertical acid concentration gradient in the ore heap, which is not generally observed in sulfide deposits. Shafer et al have verified Roman''s model and were able to predict the leaching behavior for a relatively large scale column test on coarse ore.
