Sulphide Flotation - an overview | ScienceDirect Topics

The Platsol™ process was originally developed in Canada for the treatment of flotation sulfide concentrate for Polymet Mining Company in Minnesota and subsequently tested on other PGM concentrates. This process involved codissolution of base metals (copper and nickel), gold, and PGMs via addition of chloride to the autoclave.

cobalt processing | Uses, Supply, & Facts | Britannica

Mar 04, 2020· Cobalt is again eventually obtained in the metallic state by electrolysis. Cobalt concentrates from arsenide ores may be roasted in the same manner as sulfide concentrates in order to remove the arsenic as an impure arsenic trioxide. Alternatively, they can be leached and cobalt precipitated with hydrogen, as with nickel sulfide concentrates.

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 ...

Processing of Nickel Laterite Ores on the Rise

Lateritic Nickel Ore Processing. While sulfide nickel ores are processed via upgrading to concentrates and then smelting, this approach is not applicable to laterite ores. A variety of approaches are available to process nickel laterite ores, with the most prevalent approaches explained below.

Unlocking Disseminated Nickel Sulphides using the CESL ...

4 CESL Nickel Process The CESL Nickel Process offers a method of unlocking the nickel from disseminated nickel sulphide ore bodies. It is capable of treating lower grade nickel concentrates and those with a high content of magnesia. The process can also treat bulk nickel-copper-cobalt concentrates with no need for metal

Nickel and Cobalt Ores: Flotation - ResearchGate

The nickel extraction process is dictated by the mineralogical assemblage of the sulphide and oxide nickel ores from which it occurs. The rejection of pyrrhotite, which occurs commonly with ...

Cobalt Flotation Recovery

Cobalt Flotation Studies were conducted on ores from the Viburnum trend in southeast Missouri. The Viburnum trend deposits occur along the flank of the St. Francois Mountains. Ores of the Viburnum trend are characteristically complex mixtures of the sulfide minerals galena, PbS; sphalerite, ZnS; chalcopyrite, CuFeS2; pyrite, FeS2; marcasite, FeS2; and the cobalt-nickel mineral siegenite, (Ni ...

An experimental study on leaching of cobalt and nickel from a Lubin (Poland) sulfide flotation copper concentrate with oxygenated sulphuric acid solution in the presence of iron(III) sulfate is ...

Flotation of Nickel-Copper Sulphide Ore: Optimisation of ...

the flotation recovery of Ni, Cu and Co from a nickel-copper sulphide ore. The effect on flotation performance of various parameters such as pH, collector dosage, % solids and depressant dosage at different levels was investigated. Therefore, the main objective of the study was to optimize the process parameters for the flotation of base metals ...

Flotation of Nickel-Copper Sulphide Ore: Optimisation of ...

In this study, the robust Taguchi experimental design method was used to determine the optimum conditions for the flotation of nickel, copper and cobalt from a nickel-copper sulphide ore.

Nickel | BHP

Nickel sulphide ore is mined at BHP's open-cut and underground operations in the Northern Goldfields before it is crushed and concentrated at two large nickel concentrators using nickel sulphide flotation technology. The nickel concentrate is then dried and railed to the Kalgoorlie Nickel Smelter where it's continuously fed to a flash furnace.

The present invention relates to a new hydrometallurgical process for recovering nickel from nickel bearing raw materials, such as sulphide flotation concentrates. In general, the process involves the oxidative atmospheric pressure leaching of nickel sulphide concentrates using a sodium chloride/hydrochloric acid based leach media.

Copper Nickel Flotation

To confirm the results of the batch testing and provide the cooperating company with a large sample of the cobalt nickel and copper-lead concentrates for further experimentation, pilot-plant flotation tests were made. The pilot-plant was operated 24 hr a day, except for minor interruptions for repairs and disposal of tailing.
