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 link between particle size and froth stability

Jan 01, 2020· In this work, air recovery was used as a measure of froth stability to determine the flotation response of a copper tailings ore to changes in particle size distribution and superficial gas velocity. The system exhibited a maximum in air recovery, which correlates well with the local peak in dynamic froth stability presented in previous work.

the rougher cells. The rougher tails are fed to a series of scavenger cells before exiting the plant as final tailings. Potassium amyl xanthate (~300 g/t) is the primary flotation collector reagent used, and Sodium Dia-lkyldithiophosphate (200 g/t) is added as a secondary collector. The main concern with the current process is that tailings

Coarse chalcopyrite recovery in a universal froth

Apr 01, 2019· It is well known that in the froth flotation process, recovery is a strong function of particle size. Fig. 1 shows characteristic data from Gaudin et al., 1931, Jowett, 1980, for the flotation of galena. Similar behaviour is observed with other sulfide minerals. Recovery is high between 10 and 100 µm, but outside this range, it drops quite
