Extraction of Copper. It is mainly extracted from copper pyrites (CuFeS 2). The sulphide ore is usually of very low grade and contains iron sulphide, gangue and smaller quantities of arsenic, antimony, selenium tellurium, silver, gold and platinum. The various steps involved in the extraction are: 1) Crushing and concentration

Because of the small amount of coarse copper in the ore, no problems were experienced in crushing. Only 0.005% of the feed was removed by handpicking, representing 0.4% of the copper in the ore. The -½-inch crusher product was blended and fed to a hopper which was discharged by a constant weight feeder to a 2′ x 3′ rod mill.

The primary objective of this experiment is to determine the concentration of an unknown copper (II) sulfate solution. The CuSO4 solution used in this experiment has a blue color, so Colorimeter users will be instructed to use the red LED. Spectrometer users will determine an appropriate wavelength based on the absorbance spectrum of the solution. A higher concentration of the colored solution

The production of concentrates implies the crushing and later milling of the ore down to a particle size allows releasing copper by flotation. The concentrates from different regions have approximately between 24% up to 36% of copper. Copper concentrates are then submitted to a final filtration and drying process to decrease the humidity to 8-9
