Get PriceExtraction Of Nickel And Cobalt From Sulfide Ores, The nickel sulfide is separated from the host rock by flotation crushing and froth floatation steps results in a highgrade concentrate that is a suitable feed to a nickelcobalt smelter Flotation Nickel Sulfide
The oxidation of nickel sulfide whose atomic fraction of sulfurx s is 040 to 044 was studied in a mixed o2n2 gas stream at 923 973 and 1023 k the oxygen partial pressure was maintained at 20 x 104 pa in the oxidation of nickel sulfide ofx s 040 and 041 a dense nio layer was formed on the sulfide surface without the evolution of so2 gas because of the low sulfur activity
Nickel given that many major nickel companies report annually on their sustainability performance such as eramet inco now vale inco wmc resources now bhp billiton norilsk nickel there is data available to examine in detail the differences in the environmental costs of nickel sulfide versus laterite
Colum flotation cells copper sulfide plant colum flotation cells copper sulfide plant flotation column cells are flotation act as three phase settlers where particles move downwards in a hindered settling environment countercurrent to a flux of rising air bubbles that are generated by spargers located near the bottom of the cell chat online daf induced air flotation plant
A sequential flotation process for the recovery of highgrade concentrates of copper lead and cobaltnickel from sulfide ores is provided sequential flotation of sulfide ores google patents the primary grind pulp is conditioned to depress lead iron and cobaltnickel sulfides by addition of sulfur dioxide preferably in the form of
Nickel sulfide ore flotation flocculant vhf venw nl copper sulphide ore flotation process xinhai copper sulfide ore has better floatability than sphalerite pyrite and another sulphide so it is more likely to float from the pulp by adsorpting collecting agent therefore flotation process is the main beneficiation method for copper sulfide ore

In nickelcopper sulfide ore processing serpentine is a common gangue mineral encountered in complex sulfide ores and can easily cause entrainment during flotation large amounts of serpentine in the flotation concentrate reduces the effectiveness of smelting often resulting in the imposition of smelter penalties on mineral processing companies
The bureau of mines investigated the flotation responses of two copper nickel ore samples from the duluth complex with the objective of recovering bulk sulfide concentrates one of the ores studied was taken from a test pit the other was taken from a test shaft the samples were quite similar except that the pit sample analyzed 035 pct cu and 011 pct ni and the shaft sample analyzed 069
The flotation recovery of ni cu and co from a nickelcopper 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
Jun 06 1972 what i claim as my invention is 1 a process for the flotation recovery of copper and nickel sulphide minerals from ore containing both such minerals by a process in which at least two conditioning steps precede flotation said process comprising conditioning a pulp of the ore in the presence of an alkaline agent to produce a conditioned alkaline pulp then in at least one further

Used as the collector for the flotation of nonferrous metal mineral which need strong collector but no selectivity it is a good collector for the flotation of oxidized sulfide ore or copper oxide and zinc oxide vulcanized by the sulfiding agentas well as coppernickel sulfide ores
Nickel sulfide minerals such as pentlandite can in general be separated from their gangue by flotation using a thiol group of collectors like xanthates and alkyl dithiophosphates in the presence of variety of activators depressants and dispersants since nickel sulfides contain other sulfides such as pyrrhotite pentlandite and chalcopyrite the enrichment of nickel is generally carried out
Flotation behavior of nickel sulfide ore in a cyclonic flotation column 775 in the flotation system the density of mineralized bubbles m is much smaller than that of the fluid and generally speaking the density of particles p that cannot adhere to bubbles is much higher than that of the fluid
