Mineralogy and process properties of Kolvitsky titanomagnetite ore

The authors study material composition, texture and structure, as well as process properties of titanomagnetite or from Kolvitsky deposit on the Kola Peninsula. It is found that the ore posses high potential as a unique combination of iron, titanium, vanadium, ilmenite, copper-nickel sulphides and platinum. Pre-treatment of lump material by magnetic separation allows obtaining iron-free nonmagnetic fraction after intermediate crushing. The methods of magnetic, flotation and gravity separation are discussed. The article demonstrates feasibility of integrated processing of this type with production of titanomagnetite, sulphide and ilmenite concentrates for the ferrous and nonferrous metallurgy.
