1. Introduction. Copper smelting slag is a waste source generated from copper pyrometallurgy production which typically contains 40 wt.% Fe and a considerable quantity of both environmental-hazardous and valuable metals Cu, Zn, Pb, Ni, Cr, Cd and toxic element As (Guo et al., 2018; Ma et al., 2016; Meng et al., 2020).It is predicted by ICSG forecasts that about 40 million tons of slag will be

Arsenic Removal and Recovery from Copper Smelting

Removal and recovery of high levels of arsenic (As) in copper smelting wastewater present a great environmental challenge. A novel approach was investigated for the first time using TiO2 for As adsorptive removal from wastewater and subsequent spent adsorbent regeneration and As recovery using NaOH. EXAFS results demonstrate that As(III), as the only As species present in the raw water,

Copper

Flash converting had its first application in the expansion and modernization of Kennecott's copper smelter near Salt Lake City, Utah, which was implemented during 1992-95. Coupled with flash smelting, the technology has offered a solution to strict new environmental regulations in the state of Utah.

Copper Statistics and Information

Copper is usually found in nature in association with sulfur. Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper

Flash smelting

Flash smelting (Finnish: Liekkisulatus, literally flame-smelting) is a smelting process for sulfur-containing ores including chalcopyrite.The process was developed by Outokumpu in Finland and first applied at the Harjavalta plant in 1949 for smelting copper ore. It has also been adapted for nickel and lead production.. A second flash smelting system was developed by the International Nickel

Application of Phytoremediation to Reduce Environmental

Copper smelting and refinery factories are the final stages of a pyrometallurgical processing chain, and they cause many environmental challenges around the world. One of the most common environmental problems of these factories is toxic emissions. These toxic gases have harmful effects on the vegetation, animal species, soils, and water resources around the factories.

Copper and compounds

Copper can also be used in waterways (lakes, rivers, ponds) as an algaecide. Copper exposure can also result from being near a copper mine, a copper smelter, or where copper is processed into bronze or brass. Occupational sources of copper may result from copper mining and ore processing, by inhaling high levels of copper dust and fumes.
