investigation on flotation separation of chalcopyrite from

Jan 01, 2020 · Chalcopyrite (CuFeS 2), which is a typical copper sulfide mineral, often coexists with other sulfide and non-sulfide gangue minerals, and froth flotation is the paramount method to separate the chalcopyrite from other gangue minerals prior to smelting (Agorhom et al., 2015, Li et al., 2019, Liu et al., 2019, Wei et al., 2018)

Jun 15, 2019 · Abstract. The efficient separation of chalcopyrite from arsenic-bearing minerals, especially arsenopyrite, remains a challenge in practice. In this work, a novel reagent of N-Butoxycarbonyl-O-Isobutyl Thiocarbamate (NBOIT) was employed in both single and mixed binary mineral flotation, and it proved to be highly effective for the flotation separation

The flotation separation of chalcopyrite from talc is difficult due to their good natural floatability. To solve this problem, the effect of gum Arabic (GA) on the flotation separation of chalcopyrite from talc was systematically investigated and its selective depression mechanism was discussed. Single mineral flotation test results showed the addition of GA could effectively depress the flotation of talc across …
