Manganese selection method
The vast majority of China's manganese ore belongs to the poor must be carried out mineral processing.However, the majority of manganese ore is fine-grained or micro-fine cloth inlay, and a considerable number of high phosphate, high iron ore and a total (with) wholesome metal, hence the great difficulty in mineral processing.At present, the commonly used method for manganese ore dressing machinery selection (including washing, screening, re-election, strong magnetic separation and flotation), and pyro-enrichment, chemical processing method.
1. Washing and screening
Washing is the use of water washing or additional mechanical scrubbing to separate ore and mud.Common equipment washing screen, cylinderwashing machineand trough-type washing machine.
Washing mining operations often associated with screening, such as the shaker directly flush cleaning or washing machine to obtain the ore (net ore) to send shaker screening.Screening can be used as an independent operation, separation of different particle size and taste of the product supply to use for different purposes.
2. Re-election
Currently re-election only for sorting simple structure, particle size coarse cloth embedded manganese ore, especially for the oxidation of high density manganese.Common methods of heavy media beneficiation, ore dressing and shaking jig beneficiation.
At present, China dealing with manganese oxide process, the general is broken ore to the 6 ~ 0mm or 10 ~ 0mm, and then grouped for jigging coarse level and fine level of delivery Shaker election.Equipment, mostly Haz Reciprocating Jig and 6-S-type shaker.
3. High intensity magnetic separation
Manganese compound belongs to a weak magnetic minerals
