CHARACTERIZATION AND BENEFICIATION OF IRANIAN

2013-7-1 · Manganese is used mainly in steel production, directly in pig iron manufacture and indirectly through upgrading ore to ferroalloys. Globally, the most of (90 to 95%) Mn is used in the metallurgical industry as a requisite deoxidizer and desulfurizer in steel making and as an important alloy component. Various amounts of Mn commonly are added to the steel for industrial use, making low or high Mn alloys. High grade ores (Mn content more than 42%) are usually used in metallurgical application. The remainder of the Mn (5 to 10%) is used in the chemical industry, light industry, production of dry cell batteries, in plant fertilizers and animal feed, and as a brick colorant (Fan and Yang, 1999; Lasheen et al., 2009).
