platinum group metals (PGMs) – occurring together with nickel – can be collected in iron alloys that are produced by means of reductive smelting [2, 3, 4]. There are many similarities between this process and that used commercially in the primary smelting of nickel laterite ores for …
Nickel Smelting and Refining Industry Description and Practices Primary nickel is produced from two very dif-ferent ores, lateritic and sulfidic. Lateritic ores are normally found in tropical climates where weath-ering, with time, extracts and deposits the ore in layers at varying depths below the surface. Lat-

Lead: Pay for 95% of the lead content at market value, with minimum deductions of 1.5 to 3.0 units per dry tonne.
has also found application for nickel-base alloys. Some of the more sophisticated auxiliary refining technologies are described in the light of their capability of per- forming multiple functions, like degassing, desulfurization, carbon deoxidation, pre- cise alloying, and decarburization.
Introduction. Nickel is one of the most abundant trace metals on Earth, and is widely distributed in the general environment. It is used in various occupational settings, including in mining, smelting, and refining and in the alloy production and welding industries.Workers employed in these industries are chronically exposed to nickel and related compounds, and non-occupational exposure is ...
The International Smelting and Refining Company was a subsidiary of Anaconda Copper which operated primarily out of the International Smelter near Tooele, Utah. The International Smelter began operation in 1910 as a copper producer handling ores from Bingham Canyon and was expanded into a lead smelting operation in 1912.

refining complex is to be built at Argentia, 130 kilometers west of St. John's. The Argentia complex will be the largest nickel smelting and refining facility in the Western World, producing about 122,000 tons of nickel per year.
Understanding ferronickel smelting from laterites through computational thermodynamics modelling D. R. Swinbourne* The smelting of nickel laterite ores to ferronickel alloy is unique in extractive metallurgy. It treats feed that is very low grade with respect to the target metal and, as a result, produces much more waste slag than valuable ...
