nickel sulfide ore processing

Copper extraction - Wikipedia

Sulfide ores. Secondary sulfides – those formed by supergene secondary enrichment – are resistant to sulfuric leaching.These ores are a mixture of copper carbonate, sulfate, phosphate, and oxide minerals and secondary sulfide minerals, dominantly chalcocite but other minerals such as digenite can be important in some deposits.. Supergene ores rich in sulfides may be concentrated using ...

Processing of Nickel Laterite Ores on the Rise

Nickel sulfide ores are processed by heap leaching in Sotkama, eastern Finland (Talvivaara, 2011).The process entails the following: (a) open-pit mining of 0.2% Ni, 0.5% Zn, 0.1% Cu, and 0.02% Co sulfide ore; (b) four-stage crushing; (c) rotary kiln agglomeration with sulfuric acid;

Nickel Metal: It's Properties, History, Production & Uses

Jul 28, 2019· Sulfide ores can be separated using froth flotation and hydrometallurgical or magnetic processes to create nickel matte and nickel oxide. These intermediate products, which usually contain 40-70% nickel, are then further processed, often using the Sherritt-Gordon Process.

Extraction of Nickel and Cobalt from Sulfide Ores ...

The diminishing availability of nickel sulfide ores and the increasing demand for nickel and its compounds have led to a growing interest in laterite deposits as an alternative source for ...

Nickel: smelting, producing-Metalpedia

In hydrometallurgical processes, nickel sulfide ores undergo flotation (differential flotation if Ni/Fe ratio is too low) and then smelted. 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 ...

Nickel Ore Mineral Processing 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.

Nickel | Geoscience Australia

The concentrates are then smelted (in a furnace) to produce a sulfide 'matte' with up to 70% Ni. The final stage of processing is refining, involving pyrometallurical (heating) and hydrometallurgical (chemical) processes, which are utilised differently for nickel sulfide and lateritic nickel ores. ...

'Please mine more nickel,' Elon Musk urges as Tesla boosts ...

Jul 23, 2020· Tesla doesn't disclose which nickel miners are in its supply chain. Given Tesla's focus on sustainability, the company is likely to prefer to buy from miners of higher-grade nickel sulfide, which requires less power to process than laterite ore, said Lachlan Shaw of National Australia Bank.

(PDF) Nickel Sulfide Versus Laterite: The Hard ...

There are widespread nickel resources around the world, but divided principally between nickel sulfide or laterite (oxide) resources. Historically production has been dominated by sulfide ores but ...

Beneficiation of low-grade weathered nickel sulfide ore ...

Processing nickel sulfide minerals by flotation always presents the challenge of obtaining appropriate selectivity between nickel sulfide and other sulfides, such as pyrrhotite, pyrite, and chalcopyrite. Other minerals that can reduce the process efficiency and the concentrate quality include minerals that contain magnesium (e.g., talc).

The High Temperature Co-Processing of Nickel Sulfide and ...

The processing of nickel laterites by high pressure acid leaching (HPAL) typically uses feeds with an average nickel content not less than 1.1%–1.2% (cut-off grade 1.0%) [] though recently several nickel laterite projects have been revalued with lower nickel cut-off grades based upon the cobalt content of the ore.It may also be possible to revalue a low-grade nickel laterite deposit if the ...

Mining Industry | Copper Sulfide Ore and Flotation Process ...

1 Types of copper sulfide ore (1) Single copper mineral Its ore characteristic is relatively simple, and the only useful component that can be recycled is copper. The gangue minerals are mainly quartz, carbonate and silicate. (2) Copper-sulfur ore Called copper-bearing pyrite. In addition to copper minerals, iron sulfide can be recovered, and the main mineral of sulfur is pyrite.

Nickel processing - Extraction and refining | Britannica

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 ...

Sulfide Ore - an overview | ScienceDirect Topics

For sulfide ore processing, nickel has to be separated from the iron present in the sulfide concentrate. This is conventionally done in both the smelting and converting stages. To aid iron rejection in the smelting stage, the concentrate is first partially roasted to oxidize the iron sulfide. This is done either in a multiple hearth roaster or ...

The High Temperature Co-Processing of Nickel Sulfide and ...

The pressure oxidation of low-grade nickel sulfide concentrate with high iron sulfides content generates significant amounts of sulfuric acid that must be neutralized. This acid can be utilized to leach metal values from ores such as nickel laterites. The present study demonstrates the use of a low-grade nickel concentrate generated from Poseidon Nickel Mt Windarra ore to enable additional ...
