Chalcopyrite is often the principal ore mineral in "porphyry copper deposits" as presented in class. You have analyzed the physical properties of chalcopyrite in laboratory so you already know some things about it or where to go to refresh your memory. Chalcopyrite is a sulfide mineral so this means it contains more than just copper.

Difference Between Pyrite and Chalcopyrite

Mar 29, 2016Chalcopyrite is a copper iron sulfide mineral, and its chemical formula is CuFeS 2. This mineral is naturally presented in a variety of ores; from huge masses to irregular veins and it is considered as the most important copper ore. Chalcopyrite oxidizes to several types of oxides, hydroxides, and sulfates when it is exposed to the air.

Copper-Nickel ores Danafloat Home

Copper-Nickel ores. Separation of the bulk concentrate copper and nickel minerals is generally accomplished by flotation of the copper from pentlandite and nickel-bearing iron sulphides which report to the flotation tails. Pentlandite and iron sulphides are depressed by raising the pH up to 12 with lime and a small amount of sodium cyanide.
