Parametric Optimization in RougherFlotationPerformance

Asghari et al. investigated the improvement of copper recovery in an industrial flotation circuit (Sarcheshmeh copper mine), and stated that about 95% of overall copper lost in final tailing was in the rougher circuit while the rougher flotation recovery of mixed copper ore was 8% less than the sulfide ore. Additionally, the increase of collector and NaHS dosages along with the size reduction of coarse …

(PDF)Development and optimization of mixed sulphide oxide

flotation of copper oxide or mixed ores is sulphidization, which was first developed with industrial success on Pb-Zn oxide ores in Australia (Crozier, 1991).

Parametric Optimization in RougherFlotationPerformance

The dominant challenge of currentcopperbeneficiation plants is the low recoverability of oxidecopper-bearing minerals associated with sulfide type ones. Furthermore, applying commonly used conventional methodologies does not allow the interactional effects of critical parameters in theflotationprocesses to be investigated, which is mostly overlooked in the literature.
