Nickel Smelting And Refining

Nickel Smelting and Refining 351 should be recycled To the extent possible, all pro-cess effluents should be returned to the process Treatment Technologies 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 filters Fab- ric filters may require reduction of gas
Nickel: 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
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

31/07/2019 · 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
