Iron Ore Processing
ResultIn India, where iron ore processing is one of the major industries, the generation of tailings is estimated to be 10-25 % of the total iron ore mined, amounting to 18 million tons per year (Das et al., 2000 ). The tailings contain silica in high percentage (40-60 %, from various locations). This makes it a suitable raw material for the ...

SGS MINERALS SERVICES – T3 SGS 960 11-2009
ResultBeneficiation is the process where ore is reduced in size and gange separated from the ore. Since all iron ore deposits have unique mineralogy, the beneficiation process is specific to each deposit. Separation of certain minerals can be efficiently achieved by taking advantage of the physical, electrical and magnetic properties.
