Manganese Ore Beneficiation Plant

The dressing flotation process and the process technology of manganese ore

Manganese ore, mostly belonging to lean ore, must go through the dressing process. Most of the manganese ore stones are embedded in fine grain or subtle grain form and there are a number of high phosphate rock, high iron ore and symbiotic beneficial metal. For these two reasons, dressing process has great difficulty. At present, the commonly used manganese ore dressing methods consist of mechanical selection(including wash ore, screening, re-election, strong magnetic separation and flotation), pyrogenicprocess enrichment and chemical processing method, etc.

The requirements of manganese ore stone industrial processing

In the metallurgical industry, manganese ore is mainly used for manganese base ferroalloy and manganese metal. Manganese base ferroalloy is used as deoxidier or alloy element additives for steelmaking. The manganese metal is used for smelting some special alloy steel and non-ferrous metal alloy. Manganese ore also can be directly used as the ingredients of steelmaking and ironmaking. 

In manganese base ferroalloy smelting , the manganese and ferrum are useful elements in manganese ore. The key indicator to measure the quality of manganese ore stone is manganese content. The ferrum content should have certain proportion with manganese content..

Phosphorus is the most harmful element among the manganese ore. Phosphorus in the steel will reduce the impact toughness of steel. Although sulfur also is a harmful element, the effect of sulfur limitation is better in smelting. The sulfur becomes sulfur dioxide which is easily volatilized or enters the slag with calcium sulfide, vulcanizing manganese form.

The manganese ore stone processing equipment of our company can be used for the process that the large pieces of manganese ore stone which will be crushed into small pieces.

The main crushers consist of jaw crusher, impact crusher, impact crusher, european version impact crusher and cone crusher, etc.
The more advanced process equipments for manganese ore stone are hydraulic cone crusher and european impact crusher.

Manganese ore stone application

In the national economy, manganese ore is of important value. The manganese ore is widely used for metallurgy, chemical industry, light industry and national defense industry or other departments and especially the maximum dosage is used in the metallurgical industry. In steelmaking, a small amount of manganese added can increase the steel's hardness, ductility, toughness and corrosion resistance. In steelmaking industry, manganese ore is also an indispensable deoxidizer and desulfurization agent.

The alloy made by manganese with copper, nickel or other metals, is the materials for plane, ships, and mechanical components and electrical equipment.

The types of manganese ore stone

At present, there are almost 150 kinds of the known ores with manganese content. According to the natural type, the main kinds of manganese ores are hydrated manganic hydroxide--oxidation manganese ore stone, oxidation manganese ore stone, carbonic acid manganese ore stone and oxidation manganese carbonic acid manganese ore stone. The secondary kinds are vulcanization manganese--oxidation manganese ore stone, vulcanization manganese--carbonic acid manganese ore stone, manganese borate--carbonic acid manganese ore stone and manganous silicate--Carbonic acid manganese ore stone.
