Chalcopyrite
Chalcopyrite (CuFeS 2) is a copper iron sulfide mineral and normally has a brassy to yellow golden color. This is the most abundant copper ore mineral and can be considered a "fools gold" because of its gold-like appearance. Chemical class: Sulfide. Crystallization: Tetragonal; scalenohedral; 4 2m. Habit: Crystals generally tetrahedral ...
Chalcopyrite | Common Minerals
Throughout human history, chalcopyrite has been our leading source of copper. This is despite having a relatively low copper yield (only 25% of its atoms are copper) compared to other copper minerals such as chalcocite and cuprite (both with 67% yields), or bornite and covellite (that have 50% yields). However, chalcopyrite is much more ...
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%.
