type of furnaces for manganese production
Silicomanganese Production – Process Understanding
production is reprocessed in the production of SiMn. In this way a very high total yield of manganese is achieved. 2. SILICOMANGANESE PRODUCTION Silicomanganese is produced by carbothermic reduction of oxidic raw materials in electric submerged arc furnaces. The same type of furnaces is used for FeMn and SiMn alloys.

Ferromanganese - Wikipedia
Ferromanganese is a ferroalloy with high manganese content (high-carbon ferromanganese can contain as much as 80% Mn by weight). It is made by heating a mixture of the oxides MnO 2 and Fe 2 O 3, with carbon (usually as coal and coke) in either a blast furnace or an electric arc furnace-type system, called a submerged arc furnace.The oxides undergo carbothermal reduction in the furnaces ...

Furnaces have a long history of heating homes which dates back to the Roman period, circa 1200 B.C. They used a type of warm-air heating system known as "hypocaust." But after the fall of the Roman empire, people forgot about furnaces for about 1,000 years and used fireplaces instead.It was during the 13th century when Cisterian monks began using furnaces again to warm their monasteries.
