Manganese ore processing plant

Manganese Ore Processing Plant

Manganese vast majority belong to the low grade ore, beneficiation processing must be carried out. However, the majority of manganese ore is fine-grained or micro-fine disseminated, and a considerable number of high phosphate, high iron ore, and (with) students useful metals, and therefore very difficult to beneficiation processing. At present, manganese ore election machinery (including washing, screening, gravity separation, high intensity magnetic separation and flotation), and fire enrichment, chemical processing method.

Manganese Washing and screening

Washing is the use of hydraulic flushing or additional mechanical scrubbing the separation of ore and shale. Commonly used equipment wash the griddle, cylinder washing machine and trough-type washing machine.

Washing operations often associated with screening, such as the shaker directly flush cleaning or washing machine ore (Net mine) sent shaker screening. Screening can be as an independent operation, the separation of different particle size and grade of product supply for different uses.

Manganese Gravity separation

Manganese ore, gravity separation used only for sorting simple structure disseminated coarse grain size is especially suitable for high density of oxide ore. Common methods of heavy media beneficiation jig beneficiation and shaker beneficiation.

China deal with the process of manganese oxide minerals are generally broken ore to 6 ~ 0mm or 10 ~ 0mm, then grouping the coarse level of the jig, the fine level to send shaker election. Equipment and more Haz reciprocating type jig and 6-S shaker.

Magnetic Separation Iron Ore

Single magnetite ore, mainly sedimentary-metamorphic magnetite ore. Most of the iron minerals in the ore is magnetite, embedded in fine cloth in the main; gangue minerals are mainly of silicate minerals such as quartz or hornblende. Some contain more iron silicate, such Ore production and the longest history, the ore is composed of simple, often using low intensity magnetic separation methods.

For large and medium-sized magnetic separation plant, when the grinding particles larger than 0.2 mm, often using magnetic stage grinding first; two grinding, magnetic separation of less than 0.2 mm. If coarse grinding can separate the qualified tailings, stage grinding, magnetic separation. Short of water, the dry grinding of dry magnetic separation, depleted rich magnetite ore or poor magnetite ore, usually with dry magnetic separation removed the gangue, the former block-rich ore; after grinding magnetic selected to obtain the concentrate.

In order to obtain high-grade concentrate can be magnetite concentrate with anti-flotation or hit the shock fine sieve method. In order to increase the recovery rate can be considered Tailings and other processes for further recovery.
