Extraction kinetics of target components from mineral raw materials in column devices

Abstract

Methods for predicting the kinetics of extraction of the target component from mineral raw materials for direct-flow and counter-current column extractors have been proposed. To analyze the operation of various industrial devices, the extraction processes of which are carried out in the layer, technique based on specific productivity has been proposed. The kinetic regularities of Al2O3 extraction from bauxite specs and sulfur from sulfur ore have been studied as well as the data of current countercurrent extractors from the field of hydrometallurgical plants of Ukraine have been used.
