What is The Extraction of Manganese?-xinhai

The manganese in carbonate manganese ore mainly exists as manganese carbonate or silicate manganese, with fine grain size. Flotation is the main extraction of manganese under this condition. It still has problems such as the metal large amount of lost metal, and a large amount of agent consumption.

Differences and Applications of Magnetic Separation

2021-3-16  The manganese oxide ore process concludes ore washing-jigging-strong magnetic separation process. After crushing to less than 70 mm, the ore need to be washed, sieved and classified, firstly got material with + 30 mm needs manual beneficiation, then 4.5-30 mm ore is dressed by jig, and last ore with -4.5 mm should be processed by roller-type strong magnetic field magnetic separator.
