Nickel processing - Extraction and refining | Britannica
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 production.
How is Nickel Mined - Want to Know it
Nov 04, 2012 · As nickel is commonly found with other metals, especially iron, it is mined as an ore that needs to be separated and refined to produce nickel. Nickel is often extracted from its ore by roasting at high temperatures. In some cases this is enough to separate the nickel in other cases strong chemicals are used to separate the ore.
Nickel ore oversupply looms, threatening refined prices ...
May 12, 2017 · Nickel ore oversupply looms, threatening refined prices: Russell. LAUNCESTON, Australia (Reuters) - It may be going from bad to worse for the nickel price, with conciliatory comments from the new mining minister in top ore producer the Philippines adding to the risks of the market being pushed into oversupply.
Nickel Mining and Processing: Everything you Need to Know
Nickel mining occurs through extractive metallurgy, which is a material science that covers various types of ore, the washing process, concentration and separation, stone processes and …

About nickel | Nickel Institute
Improved technologies in mining, smelting and refining, as well as increased capacities, also allow for lower-grade nickel ore to be processed. Decreasing ore grades are therefore not necessarily a sign of diminishing resources, but a reflection of innovation and improvements made …
Nickel processing | Britannica
Nickel was used industrially as an alloying metal almost 2,000 years before it was isolated and recognized as a new element. As early as 200 bce the Chinese made substantial amounts of a white alloy from zinc and a copper-nickel ore found
Cobalt extraction - Wikipedia
In the final stages, this cobalt hydroxide is redissolved and the metal is refined by electrolysis. The resulting cobalt cathodes are crushed and vacuum degassed to obtain a pure cobalt metal. Recovery from nickel-cobalt sulfide concentrates (Sherritt process)
Nickel - Wikipedia
The elements name comes from a mischievous sprite of German miner mythology, Nickel (similar to Old Nick), who personified the fact that copper-nickel ores resisted refinement into copper. An economically important source of nickel is the iron ore limonite, which often contains 1–2% nickel.
Enhanced methods for nickel recovery from low-grade ores ...
An excellent example the use of PAL on low-grade lateritic nickel ores is the Ambatovy mine in Madagascar, a joint venture between Sherritt, Sumitomo, and Korea Resources. This is one of the largest lateritic nickel mines in the world, and has the capacity to produce 60 000 tonnes of refined nickel a year, for at least 29 years.
The Worlds Top Nickel Producers
According to the International Nickel Study Group (INSG), global refined nickel production exceeded 1.9 million metric tonnes in 2013. The worlds ten largest nickel producers of that year accounted for over 60 percent of this total.

While it may be a challenge for some of the closed mines to re-open, the risks are now that they may be able to do, thereby boosting output of nickel in the worlds largest exporter of the ore, which, once refined, is mainly used to make stainless steel and other alloys.
Sulfide Ores - an overview | ScienceDirect Topics
Separation of the bulk concentrate into a nickel concentrate and a copper concentrate is usually performed when the Cu:Ni mass ratio of the bulk concentrate is greater than 0.3. These concentrates are then dried, smelted and refined in separate copper and nickel smelters and refineries. This is discussed in the next chapter.
Cobalt Metal Characteristics
Impurities (iron, nickel, copper, zinc) are removed, and cobalt is precipitated in its hydroxide form using lime. Cobalt metal can then be refined from this using electrolysis, before being crushed and degassed to produce a pure, commercial-grade metal.

THE WORLD NICKEL FACTBOOK 2018
Nickel ores are smelted and refined into primary nickel in 30 countries across the world. Thanks to usage accumulation of nickel-containing materials and the high recyclability of nickel, more and more pure nickel or nickel alloys are being recovered from nickel-containing scraps.
A New Process for Cobalt Nickel Separation
All extractions are based on the aqueous solutions with the exception of nickel which is based on organic assay, (7 mg/L and 16 mg/L nickel in Stage 1 and 2 respectively). Cobalt was extracted preferentially over nickel, but two stages and only with a large excess of organic did the raffinate finally meet the required target for Ni:Co ratio.
