Study of Kinetic Processes of the Dislocation of Iron-Containing Sulfates of Aggregated Ore

The authors study physicochemical characteristics of the kinetics of agglomerated charge dissociation at different temperatures conditions with impurities added during the melting process. The level of oxygen in the gas, the size of the ore, and the added impurities, are the main factors that determine the rate of sulfate dissociation and allow the viscosity and melting point of the agglomeration melt to be changed. The study is based on high-temperature derivatography, with which different ranges of temperature are considered and the rates of dissociation of minerals are determined. The experimental technique developed for studying the kinetics of sulfate dissociation can be used to study the thermophysical patterns of chemical and metallurgical calcination in a large group of iron-containing ore materials.
