Evaluation of the Effect of Temperature on the Ore Leaching Process Relevance

Abstract

The widespread introduction of effective bioleaching technology by the leading gold mining countries including the USA, Australia, South Africa, Canada not only allowed to increase gold production by 2-3 times over the last thirty years, but also significantly reduced the cost of ore processing [1]. Heap bioleaching is complicated at deposits in Kazakhstan because of severe climatic conditions. In this regard, it is believed that to increase the extraction of gold at the lowest cost an optimization of the temperature regime of leaching technology is needed. This can be done if there is a kinetic model that takes into account the effect of temperature on the rate of gold extraction from ore. Research ResultsWe began our research with the study of agitation leaching in the laboratory, as shown in Scheme 1. The experiment started with ore preparation. For this purpose, the selected ore was subjected Mini Review
