nickel. Process gases are cooled, and particulates are then removed by gas-cleaning devices. Nickel Refining 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 processes such as the carbo-nyl process can be used to produce high-purity nickel pellets.

Environmental Guidelines for Nickel Smelting and Refining

Nickel refining Various processes are used to refine nickel matte. Fluid bed roasting and a chlorine-hydrogen reduction will produce high grade nickel oxides (95%+ nickel). Vapor processes, such as the carbonyl process, can be used to produce high purity nickel pellets. In this process, copper and precious metals remain as a pyrophoric residue requiring separate

Nickel Refining - an overview ScienceDirect Topics

With appropriate comminution, magnetic separation, and froth flotation technology, the nickel ore may be isolated from that of iron and copper, with copper and iron as the important by-products of the nickel refining process. Concentrated nickel-bearing ore is roasted, smelted, and converted to a matte containing nickel and copper sulfides. Upon cooling, the matte forms

Does Matte Matter?

The NPI to nickel matte conversion process is a mature technology with no major step-outs from conventional processing, as it is based on an existing process. The Tsingshan process is based on one previously practiced by Eramet’s Société Le Nickel in New Caledonia to produce a nickel matte from ferronickel for their Le Havre Refinery. Eramet ceased nickel matte

Nickel Sulfide Versus Laterite : The Hard Sustainability ...

are easier to process, through conventional mining, smelting and refining, compared to laterite ores which require intensive hydrometallurgical processing (such as high pressure acid leaching or HPAL). This means that laterite ores typically require substantially more energy and chemicals to produce than sulfide nickel. Given that many major nickel companies report annually on

In this study, low grade lateritic nickel ores were processed by using carbothermal reduction to produce NP/. The used ore was from Turkey East Anatolian region. In the first experimental set, raw lateritic ore containing 0.9% Ni, 0.054% Co and 2.3% Cr was mixed with metallurgical grade coke at different stoichiometric ratios. The samples were smelted at 1600-1650 °C
