Low-grade manganese ore washing equipment

date icon

For low-grade manganese ore, ore dressing must be carried out. However, since most manganese ores are fine-grained or micro-grained and have a considerable amount of high-phosphate ore, high-iron ore and co-existing (associated) beneficial metals, it brings great difficulty to ore dressing and processing. Commonly used manganese ore dressing methods are mechanical ore dressing (washing, screening, gravity separation, strong magnetic separation and flotation) and special ore dressing methods (fire enrichment, chemical ore dressing, etc.).

Washing and screening

Manganese ore generally contains ore mud, which not only affects the grade of manganese ore, but more importantly, it will seriously deteriorate the effect of subsequent ore dressing (flotation, gravity separation and magnetic separation). Therefore, in open-pit mining or when there is a lot of ore mud, it is necessary to wash the ore first to remove the ore mud. Ore washing is to separate the ore from the mud by hydraulic flushing or additional mechanical scrubbing. It is mostly used as a pretreatment operation before ore dressing. Commonly used ore washing and desludging equipment include ore washing screen, drum ore washer, trough ore washer, low weir spiral classifier, hydrocyclone, etc.

Most manganese carbonate ores are washed, generally using vibrating screens to spray water. The product on the screen is the clean ore, and the product under the screen is returned by spiral classification and combined with the product on the screen. Overflow is discarded or further recovered manganese ore. Manganese oxide ore is generally washed once or multiple times using a double spiral trough ore washer with strong scrubbing.

Flotation process of gibbsite bauxite

1. Gibbsite bauxite needs to be crushed and ground. Due to the high hardness of this ore, it is necessary to use equipment such as jaw crushers and ball mills for crushing and grinding. The purpose of this step is to break the ore into smaller particles and separate aluminum minerals from non-metallic minerals. 2. Washing and screening are required.…

Limestone beneficiation process

Limestone generally only needs simple ore washing, and does not need to be purified by complex ore dressing process. The processing of limestone mainly involves crushing, grading, and producing quicklime, slaked lime, precipitated calcium carbonate, ultrafine (nano) calcium carbonate, carbon dioxide, etc. Limestone generally adopts dry crushing process. For limestone used in metallurgy and roads, the ore can be crushed…

Cassiterite flotation process

There are more than ten kinds of tin-containing minerals. At present, the tin used in industry mainly comes from cassiterite. Due to the high density of cassiterite (6.4-7.1g/cm3), the main beneficiation method of cassiterite is gravity separation. However, due to the brittleness of cassiterite, it is easy to become muddy in nature and during crushing, grinding and separation. Therefore, it…

Semi-dry discharge process for dehydration of bauxite washing slurry

The semi-dry discharge process refers to the process in which the slurry is transported to the slurry discharge reservoir after being concentrated to a concentration of 30% by a thickener. A dehydrating agent (dosage 300~500g/t) is added before the slurry enters the slurry discharge reservoir. The slurry is settled and stored in the slurry discharge reservoir, and the upper clear…
