Introduction. The refinery at the Bindura Smelting and Refining Company (B.S.R), Rhodesia, treats the nickel-copper-sulphide alloy that is produced in its pyrometallurgical smelting plant. The design of the refinery circuit was formulated by Outokumpu Oy, and the nickel and copper products are electrowon from solution.

The FeNi production from laterite smelting follows four main steps: drying of the feeding material in rotating kiln, calcination with coal, oil or other organic products, reduction in electric furnace and finally, refining of the molten FeNi in an electric furnace (Crundwell et al., 2011).These smelting steps also produce a huge amount of by …

The treatment of laterites has been a research hotspot in extractive metallurgy over the past decades. Industrially, the pyrometallurgical treatment of laterites is mostly accomplished with a well-established method, namely, the rotary kiln–electric arc furnace (RKEF) process, which includes three main operations—calcination, prereduction, and …
Various processes are used to refine nickel matte. Fluid bed roasting and chlorine-hydrogen reduc- tion produce high-grade nickel oxides (more than 95% nickel). Vapor …
The American Smelting And Refining Company was founded in 1899 by Henry H. Rogers, William Rockefeller, Adolph ohn and Leonard ohn. In 1901 Meyer Guggenheim and his sons took over the company. The company changed its name to ASARCO Incorporated in 1975 and has operated under that name ever since.

The Canadian nickel smelting and refining industry consists of three companies which smelt and/or refine nickel. The nickel smelting operation transforms nickel concentrates into crude metal, vvhile the refining operation upgrades metal purity. Nickel is principally recovered from two types of ore: sulphide and latente.
The primary energy consumption and greenhouse gas emissions from nickel smelting products have been assessed through case studies using a process model based on mass and energy balance. The required primary energy for producing nickel metal, nickel oxide, ferronickel, and nickel pig iron is 174 GJ/t alloy (174 GJ/t contained …
Platinum Group Metals (PGMs) are recovered through underground and open pit mining from poly-metallic sulphide ores containing PGMs, Nickel, Copper and other metals: Platinum (Pt), Palladium (Pd), Rhodium (Rh) and Ruthenium (Ru) are the most prevalent of the six PGMs, with Iridium (Ir), and Osmium (Os) found in much smaller quantities.

Keywords: laterite; smelting; RKEF process; low-grade ferro-nickel 1. Introduction According to a review published by Diaz et al., oxide-type nickel ores accounted for 64% of land-based nickel ores, but more than 60% of nickel production was based on the matte smelting of sulfide ores in 1988 [1].
Ferronickel production. Processing of laterite ores traditionally consists of a two stage process using fossil fuels (eg., coal, oil, natural gas) in the kiln operation followed by electric furnace smelting of the calcine to produce a ferronickel product and discard slag, Lagendijk and Jones (1997).
Summary. Extractive metallurgy is the practice of removing valuable metals from an ore and refining the extracted raw metals into purer form. The field of extractive metallurgy encompasses many specialty sub-disciplines, including mineral processing, hydrometallurgy, pyrometallurgy, and electrometallurgy.
