Metals Business Segments JX Nippon Mining MetalsMelting and Refining Technology for Copper Produced

The metals business produces refined copper with purity of or higher from copper concentrates having purity of around 30 As byproducts of the copper smelting and refining processes gold silver and other precious metals as well as sulfuric acid and other products are manufacturedMelting and Refining Technology for Copper Produced from Scrap Charge Our copper refining technology allows the use of higher impurity charge materials and still produce premium quality refined copper In some applications copper produced by this method may compete with copper that underwent electrolytic refining

How Mining Works Resolution CopperSmelting Wikipedia

Air is passed through the tank and the copper minerals attach to bubbles and float to the surface of the tank These bubbles containing copper are skimmed and filtered to produce a fine damp powder called copper concentrate This process upgrades the copper content from what was initially ore to a copper concentrate for smelting and refiningSmelting is a process of applying heat to ore in order to extract a base metalIt is a form of extractive metallurgyIt is used to extract many metals from their ores including silver iron copper and other base metalsSmelting uses heat and a chemical reducing agent to decompose the ore driving off other elements as gases or slag and leaving the metal base behind

The Toyo Smelter and Refinery located in the cities of Saijo and Nihama Japan are operated by Sumitomo Metals Mining Co Ltd Fed by concentrate from South America Australia and southeast Asia including that from the Sierra Gorda mine the refinery also extracts gold and molybdenum as by products from the copperCopper smelting and refining facilities produce 25 million metric tons MT of smelter slag and 15 million MT of slag tailings per year This is a large volume of slag however it is very small compared to comparable waste volumes from mining and crushing operations

Smelting and Refining ILO EncyclopaediaUSA Copper smelting process Google Patents

The smelting and refining of some metals can have special hazards Examples include nickel carbonyl in nickel refining fluorides in aluminium smelting arsenic in copper and lead smelting and refining and mercury and cyanide exposures during gold refining These processes require their own special precautions Other hazardsA copper smelting process is disclosed in which copper concentrate is smelted in a furnace to produce purified copper Flue gas discharged from the furnace is treated to produce sulfuric ac Furthermore waste liquid discharged during the production of sulfuric acid is treated to produce gypsum and the gypsum thus produced is recycled to the furnace as a flux

Processing smelting and refining gold World Gold CouncilRefining Gold HowStuffWorks

copper remains in gold 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 173 The final stage of gold production refining involves removing impurities that remain after the smelting processRefining companies receive doré 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
