ABSTRACT

ABSTRACT: The results of thermodynamic analysis of flotation systems, chemical computation and experimental researches with the use of radiochemistry, electrochemistry, spectroscopy and flotation provided fundamental information on the conditions and possibility of xanthate and dixanthogen interaction with the freshly exposed and oxidizing galena surface, the composition of the adsorption layer of collector on the mineral surface depending on pH and redox-potential values, the optimal values of pH and redox-potential of pulp for efficient flotation of galena.
