REPROCESSING OF THE OLD FLOTATION TAILINGS

• Proposed a new flotation tailings purification process Abstract Flotation waste, which was produced through seventy years of copper ore pro-cessing in RTB Bor, Serbia, is deposited in a flotation tailings pond. In total, almost 26.4 Mt could be considered as available for eventual reprocessing and reuse.

Development of copper recovery process from flotation

Jun 15, 2018 A new flotation tailings treatment process was developed for efficient Cu recovery. • An efficient Cu dissolution was achieved in an H 2 O media in presence of pyrite.. The dissolution mechanism of CuFeS 2 has been confirmed to be a multistage reaction.. Fe was always co-dissolved with Cu following a linear relation of C Fe = 38.393 × C Cu.. Over 91% Cu was extracted from

The floated material from the flotation process is also sent to the tailings thickener. The underflow from the flotation process is sent to the concentrate thickener. In the concentrate thickener, the purified slurry is thickened prior to being pumped to a disc filter. Again the addition of polymer aids in the separation and thickening process.

Froth flotation Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
