Abstract
At a global scale, depletion of large ore reserves and relative limited operation period of...
The establishment of oxygen variation in vat leaching tanks will be investigated. Experiments will be conducted by setting up leaching tanks with ore samples typical of artisanal and small-scale mining. Oxygen concentration and consumption rate will be measured using oxygen meters in different ores. Oxygen is essential during the oxidation of gold and its dissolution in the cyanide solution...
