Mining Industry Copper Sulfide Ore and Flotation Process ...

6 Copper-cobalt ore Copper mineral and cobalt-containing pyrite and other cobalt minerals. 7 Arsenic sulfide copper ore The ore has a high content of arsenic which is mainly in the form of arsenopyrite. Flotation process to solve the problem of copper and arsenic separation reduce the arsenic content in the copper concentrate as much as ...

Sulfide Ore - an overview ScienceDirect Topics

2.2.4.1 Concentration of Minerals by Comminution and Flotation. Prior to smelting the nickel and cobalt need to be concentrated from their sulfide ores. This is done by crushing and grinding the ores to liberate the nickel- and cobalt-bearing minerals from the other minerals. The ground ore is processed through two stages of flotation.

A New Process for Cobalt Nickel Separation

3.1 Basic Process for Cobalt Separation from Nickel CSIRO have developed a number of solvent extraction processes to separate nickel and cobalt together from other elements present in solution such as zinc and manganese. This technology uses a synergistic combination of two or more extractants and is thus known as SSX.

Sulfide Ores - an overview ScienceDirect Topics

Cobalt and platinum-group elements are also present either dissolved in the pentlandite or present as distinct minerals. Sulphide ores that are mined for nickel and cobalt typically contain 1.5–3 Ni and 0.05–0.1 Co. Concentration Smelting and Converting to Matte

EXTRACTING METALS FROM SULFIDE ORES

Flotation is also used to split copper and nickel sulfides and separate them from iron sulfides and gangue minerals. Cobalt sulfides appear in the nickel concentrate and the cobalt is subsequently recovered. Flotation has developed from the treatment of simple ores to the ever more complex ones that are being found today.

Nickel: smelting producing-Metalpedia

In hydrometallurgical processes nickel sulfide ores undergo flotation differential flotation if NiFe 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 ...

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.

Copper activation option for a pentlandite–pyrrhotite ...

May 30 2016 Different sulphide ores respond differently in the prospect of copper activation to thiols for froth flotation. With the BCL Selebi-Phikwe ore body pentlandite–pyrrhotite–chalcopyrite co-occur and there is the constraint of fine pentlandite dissemination in the pyrrhotite so that liberation is limited. In the presence of pentlandite pyrrhotite can even be galvanically depressed.

Nickel cobalt sulphide flotation process

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 ...

Copper-Cobalt ores - Danafloat

Sodium sulphide is conditioned in the pulp. Cobalt is floated using a combination of xanthate and dithiophosphate andor MBT. Depending on the cobalt mineralization use of an activator such as copper sulphate could provide improved metallurgy when floating with a combination of xanthate and dithiophosphate at a pH 8-9. Bulk flotation sequence ...

That means that the copper-bearing particles are initially recovered followed by carrollite in later stages of the flotation process. For cobalt the maximum final grade was observed for sample S9 with 13.0 Co and a cobalt recovery of 66.5 while the highest final recovery was observed for sample S8 with 74.4 cobalt recovery and a final ...

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 ...

WO2007039663A1 - Processing of nickel sulphide ore or ...

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 chloridehydrochloric acid based leach media.
