Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of 9999 pure copper called cathodes which will ultimately be made into products for everyday most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy respectively due to the different
Lowgrade ore is relatively simple to process while highgrade ore is a more extensive and complicated process completing offsite refining once the initial processing is done onsite the gold is transported to an offsite refinery to undergo further refining the purpose of this refining is to remove any remaining impurities
The final stage of gold production refining involves removing impurities that remain after the smelting ng companies receive dor bars as well as scrap gold and reliquefy the metal in a furnace workers add borax and soda ash to the molten metal which separates the pure gold from other precious and less precious metals a sample is then taken to a lab for tests or
Gold can be mixed with other metals like copper which is used in red gold or mercury which is used in dental gold gold is a very pliable metal and its melting point is relatively low therefore refining it by melting it and extracting the other metals from it is a practical process
Steel blanks similar to the sulphide ore refining process an electrical charge is applied to the liquid causing the copper to attach to the sheets over approximately 10 days the starter sheets fatten to a width of 25 centimetres forming 999 percent copper cathodes this process is
