iron processing, use of a smelting process to turn the ore into a form from which products can be fashioned.included in this article also is a discussion of the mining of iron and of its preparation for smelting. iron is a relatively dense metal with a silvery white appearance and distinctive magnetic properties. It constitutes percent by weight of the earths crust, and it is the oct 23, 2018 purification & concentration process is the process of using surface tension properly, magnetic or electrical separation to remove the unwanted impurities which are chemically combined or mixed with ore to increase the percentage of iron in the ore. ore-dressing process is also carried out to improve the chemical properties of ores by roasting
the exploitation of low grade iron ores is possible after enrichment. low grade iron ores contain considerable amounts of impurities including compounds of silica, alumina, calcium, and magnesium. hence the concentration process is required based on crushing, grinding for adequate liberation before the implementation of separation techniques.the concentration of ore can define as the chemical process of eliminating impurities like sand, rocks, silt, grit etc. from the ore for the extraction of metal. In simple words, the concentration of ore is the method of separating ore from the gangue, as the gangue or matrix are the valueless substances that are of
