Separation of Ferromanganese Ore Components by Reduction
Abstract Experiments confirm that selective solid-phase reduction of iron and phosphorus in ferromanganese ore is possible. A laboratory Tamman furnace at 1000°C is used, with holding for 2 and 5 h. The phase composition and phase ratio of the reduction products are investigated, as well as their chemical composition. Reductive The selective reduction of low-grade manganese ore followed by magnetic separation was proposed to produce rich-manganese ore. The optimized parameters include a roasting temperature of 1050°C, aSEM analysis for reduced manganese ore: (a) outer region

Separation of manganese and iron for low-grade ferromanganese ore
As a potential solid waste resource, low-grade ferromanganese ore has not been fully utilized or recycled. In this study, fluidization magnetization roasting and magnetic separation technologyIn the present investigation, magnetic separation studies using an induced roll magnetic separator were conducted to beneficiate low-grade ferruginous manganese ore. The feed ore was assayed to contain 22.4% Mn and 35.9% SiO2, with a manganese-to-iron mass ratio (Mn:Fe ratio) of 1.6.
