The process showed significant enrichment in Fe values ...

The iron (Fe) content of such ores ranges from 72% to 35%. The highly friable and fully liberated constituents in ore, such as alumina and silica, generate a large quantity of fines during mechanized mining and crushing. Fine gangue material or iron ore slimes having <45%–55% Fe are discarded as reject during the ore beneficiation process.

In 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. This ore was characterized in detail using …

As the overflow of the classifying cyclone contained a huge quantity of the slime material, which was abundant in iron and silica-bearing minerals (29.8% Fe and 28.9% SiO 2), desliming of this was carried out in a 25-mm-diameter hydrocyclone by varying the process variables. The mentioned optimized conditions were chosen for the …
