Small Peirce-Smith converters are commonly used for impure copper alloy scrap like red brass scrap The Contimelt process is a continuous two-stage process to melt and treat, eg high-grade copper scrap, black copper and blister copper Several of the more recently built plants are using bath smelting with top-submerged lance Isasmelt/Ausmelt .
I would like to have experts’ suggestion about an application of SX in small scale copper elector-refinery (3-5 Kt/Y) and if it is tangible, are there any successful referenc Main concept is to refine 97-98% grade copper Anodes to 99999 pure Cathodes by using SX circuit to control impuriti
The copper concentrates are fed through the flash smelting furnace with oxygen-enriched air In the furnace, the concentrates are instantly oxidized, after which they melt and separate by their own reaction heat into copper matte with a grade of 65% and slag consisting of iron oxide, silica, and other compounds Reaction in the flash smelting .
Since the first industrial application in 1940s, flash smelting has been developed for other applications than copper matte smelting, including the oxygen enriched smelting, continuous converting to blister copper with low sulphur concentration, and direct-to-blister smelting
The Outotec® Ausmelt process for copper smelting and converting provides an , to the acid plant; Improved in-plant hygiene, the Ausmelt furnace is fully sealed, , to a slag concentrator for copper recovery or granulation system to produce a.
A 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
The process is a continuous, multi-step process which produces blister copper from concentrates in three interconnecting furnac Concentrate and oxygen-enriched air (30-35% O 2 ) enter the smelting furnace through vertical lances and are smelted to produce a matte of 65% to 69% Cu and low-copper ,
The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining In a few instances, however, leaching takes the place of concentrating, smelting, and refining At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated The milling of copper ores as practiced in the larger .
