46kt/a Manganese washing cleaning recovery dryer plant

Raw material : Manganese ore grade (17.56% - 18.49% )

Final material : Manganese stone concentrate (28.31% - 31.56% ), Manganese powder concentrate ( 30.33% - 32.2%)

Recovery rate: 75 %

Flow chart process: 

The process flow diagram of the manganese ore beneficiation plant shows that the raw ore is sieved through a roller screen, and the+300mm particle size ore is separated. After high-pressure water cleaning, it enters the ore washing machine for 2 times of ore washing. The ore washing sand enters the vibrating screen, with a sieve hole size of 5mm 5mm manganese concentrate is dehydrated and enters the concentrate plant.<5mm is cleaned again by a spiral washing machine, and the mineral slurry is cleaned and recycled by a cyclone and spiral classifier. Finally, it is dried by a belt conveyor and a mining dryer and sent to the mineral powder yard.The tailings slurry is processed by filtration and dehydration through a thickener.

Manganese concentrates are divided into manganese oxide ore and manganese carbonate ore. Oxide ore is generally exposed on the surface, while manganese carbonate ore is underground.

Manganese oxide minerals are mainly composed of hard manganese ore, soft manganese ore, and water manganese ore, while gangue minerals are mainly silicate minerals, as well as carbonate mineral powder dryer materials; Often accompanied by components such as pig iron, phosphorus, nickel, cobalt, etc.

Manganese carbonate ore is a mixed primary manganese ore with high manganese, high sulfur, high silver, high lead, and zinc content, and has high comprehensive recycling value. Manganese carbonate is an inorganic compound with the chemical formula MnCO3, typically found in nature in the form of rhodochrosite.
