improved flotation performance has been achieved in test work using high-chrome grinding media as opposed to carbon steel media. the inclusion of a split-cleaner flotation circuit configuration, in which the fast-floating fraction is treated in a cleaner circuit separate from the medium- and slow-floating fractions, resulted in improved pge
when stainless steel grinding media was used, the copper flotation recovery was very high (>90 % in the rougher stage) without the addition of nahs, so its use was not warranted. the flotation of the bornite was not reduced by oxidation, in fact copper mineral recovery was the highest under the most oxidising grinding conditions.
grinding media have significant influence on the flotation of chalcopyrite and pyrite. this effect is mainly related to the change in the surface properties of chalcopyrite and pyrite. this paper investigates the influence of steel ball and nano-ceramic ball grinding on the floatability of chalcopyrite and pyrite. flotation results, as well-scanning electron microscopy (sem), x-ray
grinding media had a large effect on copper(ii) reduction on pyrite surface. mild steel medium caused more reducing grinding condition and less pyrite oxidation than 30 wt.% chromium medium. thus, more copper(ii) species were reduced to copper(i) species on the pyrite surface, which resulted in more pyrite activation by mild steel medium.
little thought had been given to the effect of grinding media on flotation selectivity of copper – lead zinc ore. ore sample. the mill feed for the pilot-plant investigation was from a copper-zinc producing mine in northwestern quebec. a 200 ton sample was made available, free of charge, thanks to the co-operation of a canadian mining company.
electrochemically inert grinding media produces more reducing conditions with lower eh and dissolved oxygen which may prevent the adsorption of thiol collectors requiring an oxidising condition [10, 12]. besides grinding environments, breakage mechanisms can also affect mineral flotation.
the type of grinding media has a great effect on mineral flotation. stainless steel media minimises the amount of iron oxidation products originated from grinding media and therefore the lignosulfonate base polymer f-100 may mitigate the negative effect of clay minerals resulting in the improved copper and gold flotation.
