Refining | Class 10, Metals and Non-metals

Refining The process of purifying impure metal is called refining of metal. The most important and most widely used method for refining impure metals is called electrolytic refining. Many metals like copper, zinc, tin, lead, nickel, silver, gold are refined electrolytically. For the refining of an impure metal by electrolysis:

Electrolytic refining - NCERT help

When electric current is passed through the electrolyte, the impure metal from the anode is dissolved in the electrolyte and an equal amount of pure metal from the electrolyte is deposited on the cathode. The soluble impurities go into the solution whereas the insoluble impurities settle down at the bottom of the anode which is known as anode mud. Following diagram shows the electrolytic refining of copper in which anode is impure copper and cathode is thin strip of pure copper while the ...

Copper Purification Process - Electrolytic Copper Refining Plant

Electrolytic refining (electrorefining) is a process used to make impure copper pure. Unlike aluminum, copper metal is fairly easy to obtain chemically from its ores. By electrolysis, it can be refined and made very pureup to 99.999%.

Electrolytic refining of copper equation

electrolytic refining of copper equation, Copper is leached out of the ore by the acid solution extraction, to produce an electrolyte suitable for electrowinning, wherein copper is extracted electrolytically much as anode copper is electrorefined. Electro-won copper is equal in quality to that produced by electrolytic refining.

Electrolytic refining - Oxford Reference

Copper(II) sulphate solution is the electrolyte. Copper dissolves at the anode: Cu Cu 2+ +2e, and is deposited at the cathode. The net result is transfer of pure copper from anode to cathode. Gold and silver in the impure copper form a so-called anode sludge at the bottom of the cell, which is recovered.

What Is Electrorefining? (with picture)

Copper is recovered from sulfide ores this way, as part of the smelting process. People first began electrorefining metal in Europe in the mid-1800s, when just a few tons per day could be processed. Now, a plant in Chile, South American can electrorefine up to 1,700 tons per day of copper.
