As much as 90 percent of manganese consumption, both in the United States and globally, is accounted for by the steel industry. Manganese removes oxygen and sulfur when iron ore (an iron and oxygen compound) is converted into iron. It also is an essential alloy that helps convert iron into steel. As an alloy it decreases the brittleness of ...

ducibility of Hainan lump ore to balance basicity is rela-tively low, but it is slightly higher than that of two pellets. Hence, the traditional view that lump ores have less re-ducibility is unilateral. Actually, the reducibility of Aus-tralia lump ore is at least a little higher than that of Brazil pellets.

Wills et al., 198710, investigated the thermally assisted liberation of cassiterite in an ore mined at South Crofty. Previous work on this ore (Sherring, 1981)14 had shown a 55% reduction in grinding resistance when the ore was heated to 650C and then rapidly cooled, however, this was greatly offset by the energy required to heat the material.
