A Study of the Kinetics of Decarbonization of Magnesite Concentrated by Flotation

The kinetics of decarbonization of magnesite concentrated by the method of flotation is studied in a laboratory under various conditions (stationary unblown layer, fluidized layer, layer mixed in a rotary furnace). Typical features of the process of decarbonization of magnesite are determined (const...

Zusammenfassung:The kinetics of decarbonization of magnesite concentrated by the method of flotation is studied in a laboratory under various conditions (stationary unblown layer, fluidized layer, layer mixed in a rotary furnace). Typical features of the process of decarbonization of magnesite are determined (constancy of the temperature of the material up to a decarbonization of 80 - 90%, self-fluidizing of the roasted material due to intense emission of CO^sub 2^ gas, etc.).[PUBLICATION ABSTRACT]
