Get PriceSecondary scrap smelters primarily use TSL furnaces and top blown rotary converters for smelting low Cu grade scrap The main smelting product is molten black copper 80% Cu which is converted to rough copper 96% Cu then fire refined and cast into anodes % Cu
Get PriceWhen the fire refining of copper was the main process it was usual to cast it to the form of wirebars for subsequent hot rolling and cold drawing to wire This souvenir was made for invited guests at the commissioning of the new Southwire Continuous copper wire rod plant on the 17th October 1974 at Enfield Rolling Mills Middlesex
Get Price· In fire refining air and natural gas are blown through the copper to remove any remaining sulfur and oxygen leaving refined copper behind to be processed into copper cathode
Get Price· The pyrometallurgical copper production route typically involves a three step process from feed to anode s melting converting and fire Two types of furnace are in use in the refining section the rotary furnace type dominates in primary copper production while secondary smelters tend to use hearth refining furnaces because they are more suitable for melting solid scrap
Get Price· Fire refining of this product instead of electrorefining also will be examined because of the absence of precious metals in cement copper Cost Evaluation Cost estimates were made for processing cement copper by the copper powder and sintered anode electrorefining processes described
Get Pricefor fire refining FRHC copper can either be cast directly The aim is to increase the metal yield and into the final product such as rods shapes the metallurgical efficiency and to optimize and billets or it can be cast into an inter energy utilization by improving the process
Get PriceA process is disclosed for fire refining copper sulfide having a copper to nickel ratio of more than about 7 3 which process comprises maintaining a molten bath of copper sulfide in a turbulent state to volatilize at least about 50 percent of at least one impurity from the group consisting of bismuth lead tin and zinc then surface blowing the turbulent bath of copper sulfide with a free
