beneficiation of a large quantity of beneficiation

Beneficiation - Wikipedia

In the mining industry or extractive metallurgy, beneficiation is any process that improves (benefits) the economic value of the ore by removing the gangue minerals, which results in a higher grade product (concentrate) and a waste stream (tailings). Examples of beneficiation processes include froth flotation and gravity...

beneficiation - an overview | ScienceDirect Topics

The major hazard of beneficiation process is bulk generation of the fine waste in slurry form or tailings. The tailing is transferred through pipe lines to the tailing ponds for settling. The top of the tailing pond can be developed as green grassy park, playground, picnic spot or for other alternative uses. The tailing mixed with...
