Abstract
This article is devoted to the study of the kinetics and the development of kinetic models of chemical reactions of minerals that occur during roasting and sintering of alumina in the tubular rotary kiln. To study the kinetics was used DSC firm NETSCH. Determination of kinetic constants and thermal effects of the individual stages were performed by solving the inverse problem in the environment of software system ReastOp. The experimental responses were used in sample mass change with time and heat speed (heat absorption).
