Beneficiation Plant of Manganese Ore

Description: Grinding is the final stage in the manganese beneficiation process and requires the most energy of all the mineral processing stages. Nowadays, there are many new types of beneficiation plant for manganese ore processing operation.

Manganese Ore Beneficiation Plant

Approximately 90% of global production of manganese is used in the production of iron and steel as a deoxidizer, desulfidizer and alloying agent. The majority of manganese production comes from South Africa, Australia, Gabon and China, where the resource is mostly mined as high grade ore. The conventional process for recovering electrolytic manganese from these sources involves high temperature reduction roasting of the residual fines (after lump material is screened and shipped for ferromanganese production) to render naturally occurring higher valent manganese species to be reduced to Mn2+ which is leachable by sulphuric acid.

Manganese ore beneficiation plant involves several processing operation according to production requirements, such as mining, crushing, screening, grinding, separation etc. Of these operations, grinding is most energy consuming and require large investment cost for grinding plants. It is important to make investigation and production plans in advance.

grinding mill for Manganese Ore Beneficiation Plant

The manganese material was found to be clayey and easily broken into fine particles. As such, a simple milling circuit concept is employed, that consists of trucking the of mine (ROM) material from the open pit and feeding through a grizzly into a feeder bin. Oversized material is crushed by forcing the material through crushing plant as per production requirements. The material is then fed through a grinding mill and trommel screen. Minus 30 mm material is stockpiled for feed into the leach system, whereas oversized material is recycled back to the grinding mill. Traditional manganese grinding mill is hammer mill. Nowadays, there are many new types of grinding plant for manganese processing operation.

Grinding is the final stage in the manganese ore beneficiation plant the most energy of all the mineral processing stages. If possible, grinding is performed wet as this requires less energy, allowing energy savings of up to 30 % compared to dry grinding. In grinding, the particles are usually reduced by a combination of impact and abrasion of the ore by the free motion of grinding bodies such as steel rods, balls or pebbles in the mill.

There are mainly several types of manganese grinding mill for sale in the manganese ore beneficiation plant world market, such as ball mill, raymond mill, vertical roller mill, trapezium mill, ultrafine mill etc. SBM is world leading mineral powder grinding and processing plant supplier, our experts can customize solution according to specific mineral properties.
