Abstract

This article considers general principle of predicting the difference in the reactivity of minerals and solvents in the conditions of their interaction at the interface between solid and liquid for cobalt minerals in the processing of mineral raw materials. The ideas of new properties of chemical affinity which allowed to carry out the forecast of a choice of efficiency of action of the dissolving reagent for opening of hardly soluble minerals of cobalt and the forecast of consecutive passing of the competing reaction proceeding on solid-liquid boundary at processing of mineral raw materials by a hydrochemical method at the level of an electron are stated. Previously unknown pattern of change the effectiveness of the solvent of the reagents and the sequence of passing a competing reaction was established, namely, that the effectiveness of the solvent of the reagent and the sequence of passing the subsequent reaction naturally varies with the calculated values given new chemical affinity (DrG0/n). It is practically proposed to use the average atomic energy of the formation of solids  ΔfG0(averaged) and calculated value of the new chemical affinity DrG0/n to create scientific basis for the opening of cobalt minerals contained in the mineral raw materials with the least time.
