Extraction degree of layer strongly depends on the input reactant concentration and the arrangement of wells at the in-situ leaching (ISL) of minerals. Therefore, solution of optimization problem of mineral leaching process is reduced to solve two problems, one of which is a problem of optimal control the intensity of reactant supply, and another - optimal arrangement of wells. In this work problem of optimal control the intensity of reactant supply is considered when the wells arrangement already is known. Above mentioned ISL method is used for mining low concentrated deposits such as uranium, copper and gold. In present work the ISL uranium mining process has been studied numerically.
