This article presents physico-chemical studies of nemalite-containing chrysotile asbestos (NCA), an associated mineral from the extraction of chrysotile asbestos ore from the Zhitikarinsky deposit, which is not used and stored in special dumps, in fact representing a man-made waste that poses an environmental hazard to the environment and the health of the regions population. During the research, samples of nemalite-containing chrysotile asbestos were subjected to chemical and diffractometric analyses in order to determine the chemical-elemental and mineralogical compositions of the selected samples. The composition of both natural nemalite-containing chrysotile asbestos and modified as a result of heat treatment in the temperature range 450–850 ºC has been studied in order to determine the possibility of its use as a secondary raw material for the production of magnesium compounds. According to the results of the conducted studies, it was found that about 60% Mg in the composition of nemalite-containing chrysotile asbestos is in the form of a mineral – brucite and 40% Mg is in the form of a component containing serpentine. The experiments carried out and the results of X-ray studies confirm that heat treatment contributes to the qualitative improvement of the physico-chemical and technological properties of nemalite-containing chrysotile asbestos when using it as a secondary raw material for the production of magnesium compounds.
