Copper LPF Leach Precipitation and Flotation Process

Copper LPF Leach Precipitation and Flotation Process

May 16, 2016 Copper is got into solution by standard leaching methods. The residue is reground, given froth flotation to recover the sulphide copper, and then refloated for its pyrite. This pyrite is calcined, producing SO2, which after reaction to H2SO4 is used for leaching. The ash is reduced with coal to yield finely divided iron.

Dec 01, 2006 The results of leaching tests applied before vitrification classify the copper flotation waste as “toxic waste” while levels of leached metals after vitrification were within regulatory limits. Thermal treatment studies at different temperatures between 0 and 600 C showed that the metal release from the copper flotation waste increased with increasing temperature and reached maximum levels …
