Copper extraction - Wikipedia. Copper ores containing chalcopyrite can be concentrated to produce a concentrate with between 20% and 30% copper-in-concentrate (usually 27–29% copper); the remainder of the concentrate is iron and sulfur in the chalcopyrite, and unwanted impurities such as silicate gangue minerals or other sulfide minerals, typically minor amounts of pyrite, sphalerite or galena.
Jan 24, 2020· c. Copper pyrites have a lesser density and impurities have higher density. Also, only the ore particles float in pine oil. Question 9. Explain the relationship between reactivity series of metals and metallurgy. Answer: Metals such as K,"Na, Ca, Mg and Al are placed above in the reactivity series.
