The principle ore of copper is copper pyrite and copper is extracted from this ore. The different steps in extraction of copper are Crushing and Concentration The ore obtained from mines are broken down into small piece by jaw crusher and then pulverized. The ore being sulphide ore is concentrated by froth floatation process.
China's top copper smelters have set their floor treatment and refining charges (TC/RCs) for the fourth quarter at $90 per tonne and 9 cents per pound.

The purest copper is obtained by an electrolytic process, undertaken using a slab of impure copper as the anode and a thin sheet of pure copper as the cathode. The electrolyte is an acidic solution of copper sulphate. By passing electricity through the cell, copper is dissolved from the anode and deposited on the cathode.
LONDON (Reuters) Miners should expect to pay smelters at least 5 percent more in 2016 to turn copper concentrate into metal, due to higher quality ore and more supply, senior officials at Aurubis, Europe's largest copper refiner told Reuters. Treatment and refining charges (TC/RCs), the cost of
Process for the electrolytic refining of copper Abstract. A process for the electrolytic refining of metals, especially copper, in which the copper is deposited from an electrolyte on the cathode of an electrolytic cell which comprises periodically reversing the current with a forward pulse time of 2 to 9 seconds and a reverse pulse time of 0.1 to 0.45 seconds.
To tie a loop in the 30 gauge copper wire, use a Blood Knot. (wrap each end around wire 4 times in opposite directions, then feed end through in opposite directions and tighten. Don't pull too hard or you will break the wire). Begin by hanging 20g mass from wire

The two gold refining methods most commonly employed to derive pure gold are the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold.
during processing are subjects of this review. Iodine value, fatty acid composition, solid fat index and congeal point are chemical and physical characteristics of oil that are affected by the hydro genation process. Techniques and effects of degumming, alkali refining, bleaching, hydrogenation, winterization and deodoriza tion are discussed.
