Copper Smelting Process

Modern copper smelters use processed copper ore fed into a flash furnace typically fired by oxygen which produces blister copper being further processed in a converter furnace Molten copper is poured from here into rectangular moulds the resulting ingots subjected to electrolysis producing a metal of 99 9% purity Copper can be recycled indefinitely without the base metal

Recycling of Copper

Secondary copper can be used for the manufacture of these materials though still within stipulated quality limits for impurities Where scrap copper is associated with other materials for example after having been tinned or soldered it will frequently be more economic to take advantage of such contamination than try to remove it by refining

Electrorefining

Lead with an even higher purity can be obtained by electrolytic refining of impure lead anodes in fluorosilicic acid H 2 SiF 6 (Betts process) Although less used than pyrometallurgical refining both primary and secondary lead producers produce refined lead using the Betts process especially when the Bi level of the bullion is high ( Gonzalez-Dominguez et al 1991 )

Copper extraction

Copper concentrates produced by mines are sold to smelters and refiners who treat the ore and refine the copper and charge for this service via treatment charges (TCs) and refining charges (RCs) The global copper concentrate market [35] was valued at US$ 81 Billion in 2019 and is projected to reach US$ 93 Billion by 2027 expanding at a CAGR of 2 5%

Cadmium processing

Refining of zinc and its cadmium content can be accomplished by treating the zinc concentrates and/or zinc-bearing secondary materials using either a hydrometallurgical or pyrometallurgical process In both processes the concentrate is converted from zinc sulfide to zinc oxide by roasting and at the same time most of the sulfur is removed as sulfur dioxide (SO2)
