ABSTRACT
The most important magnesite and talc deposits of Ukraine, Pravdinskoy, Veseljanskoe, Radionovskoe and Sivach, are characterized with relation to their genesis and industrial use. Magnesite and talc mining in Ukraine has little interface with human society and the environmental threat from the pollution of the drainage system as well as the air by emissions is minimal. The greatest and most evident environmental impact of magnesia exploitation has centered on seawater magnesia plants. The prospecting, targeted to the primary haloes, is characterized with the presence of calcite and barite and increased contents of Cl, As, Hg and Ba. More distant zones have increasing concentration of Cu, Zn and V.
