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 .

Nickel Ore Mining Process Brief Introduction Nickel ore mainly consists of copper-nickel sulfide ore and nickel oxide ore, beneficiation and processing of both methods is completely different Copper-nickel sulfide ore beneficiation methods: The most important is the flotation
When process copper-sulfide nickel ore, collector and frother will be used in order to better results A basic principle of copper-sulfide nickel ore process is that it is better to let copper assimilate into nickel ore rather than the opposite For it is easier to recovery cooper from nickel concentrate
When other elements are present, nickel has the largest individual content after copper, compared with each other element As with other copper alloys, it is necessary to distinguish between wrought alloys, which are processed to semi-finished products, and cast alloys, from which castings are produced by various casting process
Sep 06, 2017· Whether high-grade or low-grade, nickel ores need to be processed after mining, in order to upgrade their nickel content from 1-4% Ni to 10-20% Concentrating the nickel ores usually takes place close to the mine site, and involves chemical and physical processes to crush the ore and separate the nickel-bearing and gangue minerals
Oct 18, 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
The process uses sulphuric acid in high temperature, high-pressure autoclave vessels to leach nickel and cobalt from low-grade lateritic nickel ore The diagram below illustrates the Coral Bay HPAL process, through which limonite ore is processed into a mixed nickel-cobalt sulphide Taganito HPAL Nickel Corporation (THPAL)
The Caron process, which involves reduction roasting of the ore followed by ammonia leaching of reduced ore, is one of the ways in which nickel laterite can be treated It has been successfully used in processing the iron-rich limonitic part of the nickel laterite ore body

Mond Process The Mond process, sometimes known as the carbonyl process is a technique created by Ludwig Mond in 1890 to extract and purify nickel The process was used commercially before the end of the 19th century It is done by converting nickel oxides (nickel combined with oxygen) into pure nickel
Jun 12, 2014· Nickel is found in two types of deposits; Nickel laterites and magmatic sulfide depositsAlthough nickel Laterites make up 70% of the world’s nickel reserves, few of them become producing min Over the last 60 years magmatic sulfide nickel deposits produced 60% of the world’s nickel
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 differ
• The IGO Process is a valueenhancement refining process designed to treat high- grade nickel sulphide - concentrate (18%-20% nickel) as opposed to a low-grade “whole of ore” laterite feed • The significantly lower temperatures and pressures used in the IGO Process autoclave have lower risk
