Froth Flotation of Chalcopyrite/Pyrite Ore: A Critical Review

Chalcopyrite and pyrite show recovery of over 90% when working with SBX and MIBC at pH 4–10. An increase in pH to 11.5 allowed lowering the pyrite recovery to 63%. However, when using PCA, pyrite flotation was significantly reduced at pH 4–8, while chalcopyrite was slightly affected, with recoveries over 90%.Web

The extracted pyrite record represents a sample because the number of matched pyrite framboid and nodule-bearing packages (140 and 110) is almost certainly smaller than the number of pyrite framboid– or nodule-bearing rocks actually present in the focal area. The record is therefore interpreted in terms of relative proportions.Web
