Silica And Iron Recovery From A Residue Of Iron Ore
Nov 02, 2018 Siderite is an iron carbonate with a chemical formula of FeCO3 (iron carbonate), a theoretical iron content of 48.2 , a FeO content of 62.1 , and a CO2 of 37.9 . Common in nature is hard and dense siderite, the appearance of the color is gray and yellow-brown, the specific gravity is 3.8, the hardness is between 3.5 and 4, and it is non-magnetic.
At the Itakpe iron ore mine, the ratio of waste to ore is 4 1. The ratio of tailings to concentrate is commonly very high, generally around 200 1 . For instance, it has been reported that in Western Australia, on average, the production of 1 tonne of iron ore results in the generation of.
