Manganese (Mn) is a gray-white to silvery metal with a moderate melting temperature and relatively high specific gravity (7.2 to 7.4). Manganese is added to iron along with other metals and carbon, to make steel. Manganese never occurs as the native metal in nature, but instead in some combination with other elements.

Introduction. In order to beneficiate the manganese ore from their mines in the Northern Cape, Assmang established Cato Ridge Works (formerly Feralloys Limited) in 1956 and construction was started on a ferro manganese smelter at Cato Ridge approximately 60km from Durban in KwaZulu-Natal. The first alloy from this plant was exported in 1959.

More than 90% of the manganese ore mining worldwide goes to producing steel in the form of ferroalloys. What varieties are used? A variety of manganese products can give steel different properties: Ferromanganese is used as deoxidiser, desulphuriser and degasser of steel, to eliminate nitrogen and other hazardous elements that are found at the first melting of iron. It …

The obtained ore containing iron oxides are first reduced in the blast furnace or electric furnace along with carbon to yield the ferromanganese and silico furnace.This is the main product to give rigidity and to reduce corrosiveness of the steel.

The beginning of the Manganese ore processing involves a multistage crushing workflow. From there, the production of ferromanganese, the manganese ore is mixed with iron ore and carbon and then reduced either in a blast furnace or in an electric arc furnace. The resulting ferromanganese has a Manganese content of 30% to 80%. Pure Manganese used ...

At present most ferromanganese is made by smelting in the com­ mon type of iron blast furnace a mixture of high-grade manganese ore with enough iron ore to make a product containing about 80 per cent of manganese and 15 per cent of iron. Recently a small tonnage of ferromanganese has been made in the electric furnace, but informa­

For manganese-rich ore with high manganese oxide, the flux-free method can be used to smelt ferromanganese. The smelting furnace is not equipped with lime, the equipment and operation are similar to ferrosilicon, and acid slag operation is used under the condition of insufficient reducing agent.

Manganese also is a key component of certain widely used aluminum alloys and, in oxide form, dry cell batteries. As ore, additional quantities of manganese are used for such nonmetallurgical purposes as plant fertilizers, animal feed, and colorants for brick.
