Manganese Ore Crushing Process

Manganese is very much present in many minerals in nature, but only a small portion of them are really valuable enough to be mined as manganese ore. The main ones are soft manganese ore, followed by hard manganese ore, swamp manganese ore, and others such as hydromanganese ore. Both brown and black manganese ores are mixed minerals, and rhodochrosite is usually found in the presence of rhodochrosite.

In modern industry, manganese and its compounds are used in various fields of the national economy. Among them, the iron and steel industry is the most important field, using 90% to 95% of manganese, mainly as a deoxidizer and desulfurizer in the process of iron and steelmaking, as well as for the manufacture of alloys. The remaining 10% to 5% of manganese is used in other industrial fields, such as chemical industry (manufacturing various manganese-containing salts), light industry (used in batteries, matches, printing lacquer, soap-making, etc.), building materials industry (coloring and discoloring agents for glass and ceramics), national defense industry, electronic industry, as well as environmental protection and agriculture and animal husbandry, etc. In short, manganese is the most important field in the national economy, accounting for 90% to 95% of the manganese used. In short, manganese has a very important strategic position in the national economy.

Manganese is an indispensable raw material for iron and steel industry. Manganese is an extremely strong reducing agent, which can absorb all the oxygen from the steel water, so that there is no iron oxide in the steel and it becomes a non-porous steel ingot. Secondly, manganese is also an excellent sulfur remover, it can remove all the sulfur in steel, adding a small amount of manganese to steel can greatly increase the mechanical properties of steel, such as ductility, ductility, toughness and wear resistance. Manganese steel, ferromanganese and various alloys and manganese compounds made of manganese and copper, aluminum, nickel, cobalt, etc. are very useful in industry.

The production process of manganese ore processing mainly includes three processes: crushing, grinding and beneficiation. In the crushing process, three-stage closed circuit crushing is the most modern suitable for high hardness manganese ore crushing, can complete the ore crushing and part of the dissociation work, so as to improve the efficiency of the subsequent milling; in the grinding process, two-stage one-closed milling is a high-efficiency milling process, which can make the manganese ore milling more fully; in the beneficiation process, in recent years, the emergence of a more successful new process is representative of the main ones are: "stage grinding ﹑ weak magnetic separation - anti-flotation process", "full magnetic separation separation process", "ultra-fine crushing - wet magnetic separation tailing process ". The specific process configuration needs to be specifically analyzed according to the actual situation of the site, welcome to visit and exchange.
