Beneficiation of low-grade weathered nickel sulfide ore

2019-6-10  from a low-grade (~0.3% Ni) nickel sulfide ore as an alternative row material for metallurgical uses. 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

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.

flow chart for the extraction of nickle from sulfide ore

Traditionally, nickel has been processed from sulfide ores in an approach similar to copper processing, in which the ore is upgraded to concentrates and then smelted. As sulfide ore resources dwindle, however, processing of lateritic nickel ores is becoming of greater necessity, with many recognizing nickel laterite ores as the future of the...

Nickel Sulfide Versus Laterite : The Hard Sustainability

2009-9-22  Nickel is commonly present in two principal ore types sulfide or laterite ores. Sulfide ores are typically derived from volcanic or hydrothermal processes and usually include copper (Cu) and/or cobalt, and sometimes other precious metals such as gold or platinum and palladium (generally grouped as platinum group metals or PGMs).

2020-8-17  With nickel found in two radically different types of ore, it is not surprising that the mining methods differ. Sulfide deposits are usually mined by underground techniques in a manner similar to copper, although some deposits have been mined using open

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, solvent extraction is used to separate the cobalt and nickel, with the final nickel

Guides For High-sulfide Gold Processing

2020-3-17  High sulfide gold ore refers to a certain gold ore with 20% -30% of gold wrapped by sulfide (mainly pyrite). Because most of the gold in high-sulfide gold ore exists in the form of sulfide-encapsulated gold, when using direct leaching process, the consumption of gold leaching agent and cost of gold leaching production will increase, and gold processing

The present invention relates to a new hydrometallurgical process for recovering nickel from nickel-bearing raw materials, such as sulfide flotation concentrates. In general, the process involves leaching at oxidative atmospheric pressure from nickel sulfide concentrates using a bleach medium based on

Nickel Sulfide Versus Laterite : The Hard Sustainability

2009-9-22  different locations, depending on local geographic factors. The processing of sulfide ores in this manner is known as pyrometallurgy, with copper (Cu) either an important by-product or co-product (depending on ore grades). Conversely, nickel production from laterite ores is relatively complex. Laterite mines are all open
