THE MECHANISM AND KINETICS OF PHYSICAL AND CHEMICAL PROCESSES PROCEEDING AT ORE CRUSHING

Abstract

The mechnism and kinetics of physical and chemical processes taking place at crushing oxidized ores are observed. It is shown that the mechanical activation based on spinel is a special method for obtaining amorphous substances during which the crystal mesh transfers from the ordered state into the disordered one. By increasing the duration of mechanical activation, the spinels change from the initial state into the active state, and as a result, structural and chemical changes take place at physical and chemical activity of the spinel oxide structure. Researches are conducted to explain the structural changes of activated spinels.
