Correlation of technological parameters in in-situ uranium leaching

The present-day international and domestic researches in the field of mining pay a considerable attention to mathematical modeling of the main indicators of geotechnological processes. The research basis is the practical experience of mines and the main relationships that make it possible to predict certain parameters of mining operations. This article presents an approach which embraces a fairly extensive selection of statistical data on operation of insitu uranium leach mines (Khiagda deposit). The domestic literature discusses a wide range of problems connected with physicochemical methods of mineral mining. Basically, the studies are reduced to describing particular processes without statistical processing of key figures. The chief problem is the lack of a mathematical apparatus to predict the useful component content during dissolution at various stages of leaching. This study, using specialized software, makes an attempt to correlate the influence exerted by concentrations of reagents and by flow processes in aquifers on the effectiveness of dissolution of the useful component. The purpose of the study is creation of a multiplicative mathematical apparatus, flexible enough to allow adaptation to variable operating conditions.
