Generally, the flotation tailings are produced from beneficiation process of copper ore Due to increased exploration of copper ores and the discovery of more low–grade deposits, it can be expected that more flotation tailings will be produced in the coming years, which might cause more environmental problems.
Dewatering of Copper Flotation Tailings: Effect of Feed …
Aqueous slurries' dewatering using gravity-driven thickeners is an essential unit operation in mineral processing. Thickener feed dilution is often used for enhanced flocculation and sediment compressibility. This work investigated the effect of feed dilution on thickener performance for copper flotation tailings.
Flotation Tailings from Cu-Au Mining (Bor, Serbia) as a
The copper content of old flotation tailings is similar to the world average content of about 0.4% copper in mined ore. Taking into account the current price of copper on the stock market and predictions that copper demand will increase, flotation tailings and low-grade copper ores represent a potential future source of copper [18,36,42].
Economic potential and environmental impact of metal …
After copper recovery by flotation, the remaining part of the slag is considered waste and disposed of in the slag dump area. However, even after copper recovery, copper slag flotation tailings (CSFT) may still contain several metals in varying amounts. However, the complexity and low metal concentration have undermined the potential of CSFT.
