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 ().There are many different types of beneficiation, with each step furthering the concentration of the original ore

Mine tailings: reprocess, recover & recycle The

The remaining 10% of copper, around 111kt, went to tailings. If the average copper price in 1999 was US$1,500/tonne then that 10% represented US$166.5 million of metal. Fast forward 20 years and at today’s price, US$5,842/tonne, if that material could be reprocessed and an extra 2.5% of copper recovered (or more), then that’s an additional

Tailings Pond 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.
