2014.4.3 Beneficiation of Iron Ores. Iron ore is the fourth most common element in the crust of the Earth. Iron (Fe) is necessary for the production of iron and steel and hence an essential material for the economic development of a nation. Majority of the iron ore resources around the world are composed of metamorphosed banded iron formations

This is a partly physical and partly chemical beneficiation used to concentrate ores of copper, lead, and zinc. These metals have considerable affinity for sulfur. (the table on the metallurgy section lists sulfide ores for each of them.) The ore is ground and suspended with water in large tanks. Flotation agents such as the xanthates are added ...
