MEI's Barry Wills: Challenges in copper flotation
2011-9-10 But perhaps the biggest challenge in copper flotation is that of copper oxides which have very poor floatabilities and are usually treated by hydrometallurgical methods, such as vat and heap leaching, sometimes in association with solvent extraction.

2015-7-1 The poor liberation of copper–arsenic minerals makes selectivity difficult during copper sulphide flotation. Consequently, fine regrinding is required to liberate these minerals to enable differential flotation of the copper–arsenic and the primary copper minerals.

Development of copper recovery process from
2018-6-15 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 and challenges. The total copper recovered from its ore through flotation process is about 56% [6,18], which indicates that the flotation tailings still contain valuable copper components such as chalcopyrite. In addition, old flotation tailings

2020-7-6 A much more difficult mineral processing challenge is the selective flotation of arsenic-bearing copper minerals (e.g., enargite, Cu 3 AsS 4, and tennantite, (Cu, Fe) 12 As 4 S 13). These minerals have flotation characteristics very similar to non-arsenic-bearing copper minerals (chalcopyrite, chalcocite and
