Annotation: A study of the thermal treatment of serpentinite in the Karakalpak deposit is given in this paper. According to the DPV data, the first endothermic effect associated with the removal of adsorbed water was obtained at a temperature of 170°C, and the second was bound by the fusion at 680°C (a mass loss of 10%). Thermal treatment of serpentinite is an important step in its processing technology. When choosing the optimal thermal treatment of serpentinite, a thermoanalytical study is necessary to study the dehydration of serpentinite, which is the main chemical phase of firing. Based on this, in this work, we investigated the phase composition of intermediate and final products of heating serpentinite in the Karakalpak deposit.

Keywords: dehydration of serpentinite, DPV data, heating, magnesium.
