To do so, raw copper is electrolysed in a copper sulfate solution. The raw copper is used as the anode. Here, the ignoble elements and copper will dissolve. At the cathode (also made from copper), pure copper is deposited. In this experiment, the copper refinement is conducted using a brass electrode (copper, "contaminated" by sinc).

(1.6 millon tons) of ore produced in 1991. Copper is produced in the U. S. primarily by pyrometallurgical smelting methods. Pyrometallurgical techniques use heat to separate copper from copper sulfide ore concentrates. Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining.
The refined blister copper is poured into casting molds lined up side by side on the revolving circular table of a casting wheel and cast into anode plates for electrolytic refining. The anode plates are approximately 1m x 1m x 0.05m in size, and weigh 380 kg per plate.
Fire-refined copper is adequate for noncritical applications such as water tubing, bar stock, or ingots for alloying. Copper intended for electrical uses, however, is produced by electrorefining or sometimes electrowinning techniques. Electrorefining process Virtually all copper produced from ore receives an electrolytic treatment at some stage
In the metal refining of ores, the metal is solubilized in an aqueous solution. The optical control of metal refining requires quick, accurate analysis of the major chemical species present in solution. Raman spectroscopy and resonance Raman are used to identify the amine complexes of Co, Ni, and Cu species, as well as ammonia sulfate and ...

Dec 18, 2016· Major Ores include chlorargyrite (AgCl), argentite (Ag2S) and pyrargyrite (Ag3SbS3). The major sources of silver are lead ores, copper ores, lead-zinc ores and copper-nickel ores found mostly in Mexico, Australia, Bolivia, Serbia, Peru, Chile, China, and Poland. Silver is produced mainly as a byproduct of the electrolytic refining of gold ...
For instance, most copper today comes from deposits averaging as little as 0.4% Cu, whereas some 50 years ago the average copper ore contained about 2.0% Cu. Lower grades mean that more rock has to be mined, crushed, and treated for each unit of resulting ore concentrate. It is noted, as a general rule, that with decreasing grade of ore the ...

Properties of Copper Ores The Problem Minerals from which copper can be extracted to make money are called copper ores. There are several copper ores, but they all fall into two main categories: oxide ores and sulfide ores. Oxide ores contain oxygen. Sulfide ores contain sulfur. Azurite, malachite, and chrysocolla are a few examples of oxides ores.

grade ores and continually reduce the costs of production. Economies of scale have been real-ized in all phases of copper production. Both ma-chine and human productivity have increased dramatically. This chapter briefly describes the technology for producing copper, from exploration, through mining and milling, to smelting and refining or
The treatment of copper scrap consisted of copper smelting and converting, copper electrorefining, anode slimes purification by H 2 SO 4 leach (to remove Cu + Ni), doré smelting and silver electrorefining in a Thum cell, gold mud leaching with aqua regia, gold reduction with SO 2, and selective precipitation of red and yellow salts.
The concentrate is then purified further through a refining process. The copper is now nearly 99.99% pure, and is cast into distinct shapes, ready for shipping to world markets. Step 4. Oxide ore – treatment process: Copper is liberated from oxide ore through a chemical process known …
