Nickel processing - Extraction and refining | · Nickel processing - Nickel processing - Extraction and refining: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel

What Is Nickel Smelting? (with picture) - wiseGEEK

· Nickel smelting is the process that nickel ore goes through to eventually remove impurities and leave just the nickel metal. While the ores can come from different stones and sources, they have two categories: lateritic, or rocks found in tropical climates and which contain nickel; and sulfidic ore, which is mined from underground.Environmental Guidelines for Nickel Smelting and RefiningEnvironmental Guidelines for Nickel Smelting and Refining Industry Description and Practices Primary nickel is produced from two very different ores—lateritic and sulfidic. Lateritic ores are normally found in tropical climates where weathering will, with time, extract

The discharge of particulate matter emitted dur-ing drying, screening, roasting, smelting, and converting is controlled by using cyclones fol-lowed by wet scrubbers, ESPs, or bag 12.3 Primary Copper Smelting12.3 Primary Copper Smelting 12.3.1 General1 Copper ore is cobalt, tin, nickel, tellurium, silver, gold, and palladium. A typical pyrometallurgical copper smelting process, as illustrated in Figure 12.3-1, includes 4 steps: roasting, smelting, concentrating, and fire refining. Ore concentration is roasted to reduce impurities, including

Cobalt extraction - Wikipedia

Cobalt extraction refers to the techniques used to extract cobalt from its ores and other compound ores. Several methods exist for the separation of cobalt from copper and nickel . They depend on the concentration of cobalt and the exact composition of the used ore .How to nickel smelting mill - ontwerpbureau How to nickel smelting mill.

Processing, smelting and refining gold | World The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold.

Nickel: smelting, producing-MetalpediaNickel: smelting; Extraction and purification; Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel applications, 75% pure nickel can be used without further purification, depending on the composition of the impurities.
