Nickel processing - Extraction and refining | Britannica
In this process, the ore is mixed with special reagents and agitated by mechanical and pneumatic devices that produce air bubbles. As these rise through the mixture, the sulfide particles adhere to their surfaces and are collected as a concentrate containing 6 to 12 percent nickel.

Nickel Mining and Processing: Everything you Need to Know
The Nickel Mining Process 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 the extraction process.
concentrate nickel processing
The Long Harbour Nickel Processing Plant is a Canadian nickel concentrate processing facility located in Long Harbour, Newfoundland and Labrador. Operated by Vale Limited, construction on the plant started in April 2009 and operations began in 2014.
Processing Nickel Ores - Mine Engineer.Com
The copper concentrate is sent to the copper smelter and 99.99% copper cathode is produced in electrowinning cells. The nickel ore is sent to the nickel refinery, where a complex set of reactions is carried out. These include leaching in autoclaves using ammonia, heated to around 200 deg F at elevated pressures of 100-150 PSI.

Nickel Ore Mineral Processing
Copper nickel can be get from raw ore, then the copper concentrate with low grade nickel and the nickel concentrate with low grade copper can be separate from the mixing concentrate, the nickel concentrate will be sent into the next stop-smelting, nickel matte can be get and then it …
Nickel: smelting, producing-Metalpedia
After producing the nickel matte, further processing is done via the Sherritt-Gordon process. First, copper is removed by adding hydrogen sulfide, leaving a concentrate of only cobalt and nickel. Then, solvent extraction is used to separate the cobalt and nickel, with the final nickel …
nickel ore processing plant crushing
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 ...

Long Harbour Nickel Processing Plant, Canada
Vales objective for the nickel processing plant is to process concentrate from the mine / concentrator in northern Labrador to produce finished nickel product and associated cobalt and copper products. The project was built on a partially brownfield site near the port of Long Harbour.
Nickel - Wikipedia
Nickel is a silvery-white metal with a slight golden tinge that takes a high polish. It is one of only four elements that are magnetic at or near room temperature, the others being iron, cobalt and gadolinium.Its Curie temperature is 355 °C (671 °F), meaning that bulk nickel is non-magnetic above this temperature. The unit cell of nickel is a face-centered cube with the lattice parameter of ...
Extractive Metallurgy of Nickel, Cobalt and Platinum Group ...
The precipitate, a mixture of nickel and cobalt sulfides, is sent to a nickel–cobalt refinery for further processing. An alternative to mixed sulfide precipitation is to either treat the solution directly or to precipitate mixed hydroxide or mixed carbonates.

DOWNSTREAM NICKEL SULPHATE STUDY UPDATE
• 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
Nickel
The ore extracted from Raglan Mine is crushed, ground and processed on-site to produce a nickel-copper concentrate, which is then sent to the Sudbury Smelter for further processing. The concentrator treats approximately 1.3 million tonnes of ore yearly, resulting in more than 38,000 tonnes of nickel-in-concentrate annually.
Nickel and Cobalt Production - ScienceDirect
The primary processing of nickel and cobalt is complex, and many routes are taken to produce a salable product. These routes depend upon the original ore and the technology expertise and existing capacity of the producer. Nickel and cobalt often occur together in either oxide (laterite) or sulfide ores. Each type of ore is processed differently.
