Tata Magnitogorsk deposits of niobium deposit in Russia is currently the only industrial use. Industrial reserves were calculated for weathered crust-like ores containing 0.7% Nb 2 O 5 and 9% P 2 O 5 . Mineral carriers niobium and niobium is pyrochlore iron ore. Russian Institute of Scientific Research Institute of rare metal and mineral raw materials Russia scientific development of re-election - flotation joint beneficiation process, in order to guarantee access to meet the standards of columbite - pyrochlore concentrate and apatite concentrate. The preparation process of ore dressing includes washing with a barrel scrubber to remove +15mm grain size, -15mm grain size screening machine by 2mm grain size and 0.5mm grain size, and mud +15mm grain size to crush to 10~ 15mm. The prepared product was re-elected with a jig, a spiral concentrator and a spiral chute; the -2 mm grain size coarse concentrate was selected with a shaker. The apatite-yelite coarse concentrate containing 3% to 7% Nb 2 O 5 and 20% P 2 O 5 was reground to 0.3 mm and selected by magnetic separation, re-election, and flotation (Fig. 1). Figure 1 Tartalsk deposit ore selection principle process Apatite flotation is carried out at a pH of 9 to 9.5 in the presence of water glass using a fatty acid as a collector , followed by flotation of the apatite from the apatite in the presence of soda and water glass. in the flotation of mica products. After washing the liquid phase, the product in the tank was treated with sodium silicate fluoride, and the chlorite was floated with the No. 8 collector. After sweeping, the product in the tank is ground to -0.15mm and given to the flotation and flotation operation. The products in the tank for re-flotation are selected with a shaker. The re-election of the ore and tailings obtained from the apatite beneficiation is fed into the flotation selection process. The Nb 2 O 5 grade of antimony concentrate is 60% to 62%, and the recovery rate is 75%. The above-mentioned coarse concentrate selection process has been industrially applied at the North Rhine-Westphalia Vishlevogorsk Mine Select Plant. This process is now being applied in the retrofit of the Tatarsk Concentrator in order to achieve a selection of coarse concentrates.
