Kolvitsa field (geology, material composition of ores)

Abstract. Findings on the geological structure, texture, mineral and chemical structure of the Kolvitsa titanomagnetite ore deposit have been reported with a history of discovery and exploration attached. For the first time, a full composition of minerals and enclosing rocks of the deposit has been presented. It has been shown that the titanomagnetite mineralization is accompanied by a copper-nickel sulfide mineralization where the principal minerals are pyrrhotine, pentlandite, bornite, cubanite, walleriite, and makinavite. High contents of nickel, copper and cobalt impurities are caused by sulfides of the titanomagnetite ore. On this basis the Kolvitsa iron-titanium-vanadium ore field has been proposed to be considered a complex Fe-Ti-V-Ni-Cu-Co deposit.
