Most sulfide deposits have traditionally been processed by concentration through a froth flotation process followed by pyrometallurgical extraction In hydrometallurgical processes nickel sulfide ores undergo flotation differential flotation if NiFe ratio is too low and then smelted.

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.
However the poor nickel floatability into the bulk concentrate indicated that TBP can be an effective flotation reagent for differential flotation of Cu Ni bearing concentrates to preferentially depress pentlandite TBP is likely to play duel role in augmenting the copper recovery while depressing the nickel sulphide minerals.

Flotation of Nickel Abstract Froth flotation is widely used for concentration of base metal sulphide minerals in complex or One of optimum conditions for the flotation of nickel copper and cobalt from a nickel copper sulphide ore The parameters parameters for the flotation of base metals from a nickel copper sulphide ore 2 Materials and Methods 2 1.
A sequential flotation process for the recovery of high grade concentrates of copper lead and cobalt nickel from sulfide ores is provided A primary grind ore pulp is conditioned with SO 2 as H 2 SO 3 under intense aeration and the conditioned pulp subjected to sequential flotation with regrinding and conditioning of a copper rougher concentrate obtained in the first flotation step for copper.
The objective of the project described here has been to investigate the feasibility of the chlorination based process for treating copper nickel sulfide flotation concentrates from the Duluth.

Jul 26 1995018332There is presently no known successful commercial application of a pyrite arsenopyrite differential flotation process The use of sulfur dioxide for depressing sphalerite ZnS during the flotation of pyrite is well established Similarly Canadian patent 1 238 430 teaches the use of sulfur dioxide to separate copper and iron sulfides from.
Antimony Ores Separation Flotation Process Plant 1 Froth Flotation Introduction Ore Flotation Machine is mainly used to select non ferrous metals such as copper zinc lead nickel gold etc and also be used for coarse selection and selection of black metal and nonmetal.
Arsenopyrite is separated from a mixture with pyrite by contacting the mixture with a sulfitic agent providing HSO3 ions at elevated temperature and pH below about 8 for a period sufficient to impart a selective depression property to the arsenopyrite On addition of a collector the pyrite is rendered floatable enabling froth flotation to achieve a concentrate rich in pyrite and tailings.
