The mono crystal mineral analysis by conducting magnetic separation and froth flotation to upgrade the ore under study it was found that when the ore is ground to 60 finer than 0076 mm iron concentrate of over 65 iron grade is obtained and the sulfur content of concentrate can be reduced to 035
Unlike mineral sulfide ores iron ore does not provide an energy source eg ferrous and sulfur compounds for the oxidative growth of bioleaching microorganisms however ironreducing bacteria which gain energy by the dissimilatory reduction of ferric iron to ferrous iron may be useful in upgrading iron ore read more
Iron processing iron processing iron processing the metal most blast furnaces are linked to a basic oxygen steel plant for which the hot metal typically contains 4 to 45 percent carbon 06 to 08 percent silicon 003 percent sulfur 07 to 08 percent manganese and 015 percent phosphorus tapping temperatures are in the range 1400176 to
May 18 2017nbsp018332until the 1950s of the last century the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm however the depletion of highgrade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore because of these processes a fine granulometry is produced and thus iron agglomeration
Steelmaking the basic oxygen process impurities in the iron from the blast furnace include carbon sulfur phosphorus and silicon these have to be removed removal of sulfur sulfur has to be removed first in a separate process magnesium powder is blown through the molten iron and the sulphur reacts with it to form magnesium sulfide
