The article presents the results of the Svintsovye Tundry ore occurrence ferruginous quartzite mineral and chemical composition studies. Ores dressability processing studies included dry and wet magnetic separation with different degrees of ore grinding, as well as gravity concentra- tion of non-magnetic products. With respect to mineral composition, ores are classified into two types: 1) magnetite-quartz - characterized by a lower content of Fetot, but also by a high proportion of magnetite iron and a low proportion of iron bound with silicates; regarding slag- forming elements, Mg, Al, K, Na, Ti oxides concentrations are increased; regarding microelements - Ni, Zn and Pb; 2) silicate-magnetite- quartz - characterized by increased content of Fetot, and a high proportion of metal bound with silicates, with P2O5 content being increased. Wet magnetic separation concentrates grade is high - 68.7 %, a number of samples provided for production of superconcentrates with mass fraction of Fetot being over 70 %. Conce
