Talc-magnesite is a complex mineral raw material that serves as a valuable commercial product with a wide range of applications in various industries: from metallurgy, oil production, and oil refining to the light and food industries. The Zinelbulak deposit (Karakalpakstan, Republic of Uzbekistan) is believed to be the only deposit of talc stone in Central Asia. Geologists estimate its resources at approximately 200 million tons. This article describes various possible applications for the talc-magnesite minerals, established following a comprehensive ore composition study for the deposit. Chemical, X-ray phase, IR-spectroscopic, differential-thermal, and gamma-spectrometric methods were used to study the qualitative and quantitative mineral composition of talc-magnesite at the Zinelbulak deposit in order to establish the prospects for the use of its talc-magnesite ore as a priority raw material for the manufacture of magnesiumcontaining products. It has been established that the key minerals of the talc-magnesite studied are talc and magnesite with a high content of magnesium (up to 31.7 wt%) and iron. These minerals have favorable morphological and strength characteristics, are free of any toxic substances, and represent an ideal raw material for multiindustry use. Serpentine, enstatite, quartz, hematite, and magnetite are present in association with talc-magnesite. The paper presents the results of a study with talc-magnesite roasting at 500–700 °C and hydrochloric acid leaching to obtain magnesium chloride and chlorate from the ore of the Zinelbulak deposit. It has been shown that, in order to obtain magnesium chlorate, the magnesium chloride isolated with the use of ammonium dihydrogen phosphate was converted into sodium hypochlorite.
