Popis:	The present article deals with the problems of drying kinetics with regard to ill-conditioned alumina. Relations of removed moisture quantity and alumina trial retention interval are determined as well as moisture residual quantity in the alumina on the retention interval. The paper materials prove the possibility of alumina acquisition taking into consideration its prolonged transportation to the Russian intracontinental plants and a considerable amount of crystallized moisture, up to 1% or more, and the corresponding growth of the fluorhydric acid quantity being released into the atmosphere. The investigations of fluorhydric acid releasing into the atmosphere were carried out.
