Abstract
Technological and mineralogical studies of samples of burnt limestone and pre-treated concentrate were performed. The processes of changing the mineral composition and moisture content of the MMC concentrate during its prophylaxis with burnt limestone have been studied. The mechanism and kinetics of water binding of wet iron ore concentrate in the process of mineral hydration are described. It is shown that almost all the minerals of burnt limestone participate to a certain extent in the process of concentrate prophylaxis. It has been experimentally established that the prophylaxis process takes place during the day, but the process is most intense in the first 4 hours after mixing the wet concentrate with burnt limestone.
