Nickel processing | Britannica, The nickel content of laterites varies widely: at Le Nickel in New Caledonia, for example, the ore delivered to the smelter in 1900 contained 9 percent nickel; currently it contains 1 to 3 percent Mining With nickel found in two radically different types of ore, it is not surprising that the mining methods differNickel processing, 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 ,The beneficiation process of nickel ore,copper, Nickel ore is mainly divided into copper-nickel sulfide ore and nickel oxide ore, and their beneficiation and processing methods are completely different The main method for beneficiation of copper-nickel sulfide ore is flotation, while magnetic separation and gravity separation are usually auxiliary beneficiation methodsNickel Ore Sorting : TOMRA, Nickel sorting that utilizes our cutting-edge sorting technology has many benefits Sorting and dumping of waste rock at the shaft considerably reduces transportation costs of the upgraded nickel ore to the distant processing plantMetal Profile of Nickel, The separation process for nickel is highly dependent upon the type of ore Nickel sulfides, such as those found in the Canadian Shield and Siberia, are generally found deep underground, making them labor intensive and expensive to extract However, the separation process for these ores is much cheaper than for the lateritic variety, such as ,.
