optimum conditions for the flotation of nickel, copper and cobalt from a nickel-copper sulphide ore. The parameters investigated include collector dosage, percentage solids, depressant dosage and pH. The effects of these parameters at three different levels on the recovery of Ni, Cu and Co were investigated using an L 9 Taguchi orthogonal array. The optimum conditions for the recovery of the ...
The flotation of copper-nickel ore has the following four basic processes. Directly use priority flotation or partial priority flotation process: When the copper content in the ore is much higher than the nickel content, this process can be used to select copper into a separate concentrate. The advantage of this process is that copper concentrate with low nickel content can be directly ...
The useful minerals of Jinchuan high-grade copper and nickel suphfide ores were mainly nickel and copper, whose grade were respectively 1.42% and 1.01%. The content of MgO and SiO2, main gangue components, reached 57.89%. The key to improve the separation indexes of flotation concentrate was to inhibit the gangue minerals effectively, therefore, the effects of different kinds of regulators on ...
Copper Nickel Flotation. 2020-7-21 Cyclic Copper Nickel Flotation Tests. To further clarify the flotation response of the shaft sample, several cyclic tests were carried out. A 6-min grind in the laboratory ball mill was selected for these tests, and the result was a 40-pct minus 325-mesh grind. The flotation procedure used was to condition 600 ...
Copper- Nickel Ore Flotation Process. When process copper-sulfide nickel ore, collector and frother will be used in order to better results. A basic principle of copper-sulfide nickel ore process is that it is better to let copper assimilate into nickel ore rather than the opposite. For it is easier to recovery cooper from nickel concentrate. The process has a vital advantage-receive copper ...
Separation of the bulk concentrate copper and nickel minerals is generally accomplished by flotation of the copper from pentlandite and nickel-bearing iron sulphides which report to the flotation tails. Pentlandite and iron sulphides are depressed by raising the pH up to 12 with lime and a small amount of sodium cyanide. Elevating the slurry temperature to 30-35 degrees C may improve the ...
In nickel-copper 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 [].
Nickel And Copper Flotation. All the flotation testwork was done using the Denver laboratory machine with a 15l stainless steel flotation cell The required mass of nickelcopper sulphide ore material ground to 70 passing 75 µm was weighed and placed in the flotation cell This was followed by the addition of distilled water to about Get Price. Our Products. Our products sell well all over the ...
gangue minerals, thus leading to nickel loss. Flotation Practice in Nickel Sul\de Deposits Nickel sulRde minerals such as pentlandite can, in general, be separated from their gangue by Sotation using a thiol group of collectors like xanthates and alkyl dithiophosphates in the presence of variety of activators, depressants and dispersants. Since nickel sulRdes contain other sul Rdes such as ...

After the copper, nickel and cobalt sulfides are precipitated in the suspension resulting from the attack, the precipitated medium undergoes a flotation treatment to separate these sulfides from the gangue or deads, on the one hand, and from the aqueous fraction of the suspension, on the other. To do this, a collecting agent is introduced into the suspension resulting from the precipitation of ...
An aqueous slurry of a nickel-cobalt-copper sulfidic flotation concentrate, typically containing 5 to 25% Ni, 1 to 10% Cu and 0.2 to 1.0% Co, with a particle size corresponding to a d 80 of 40 to 80 microns, is fed to an attritor mill in fine grinding step 12 to reduce the particle size to a d 80 in the range 10 to 30 microns. The slurry of finely ground sulfidic flotation concentrate is mixed ...
Froth flotation cells to concentrate copper and nickel sulfide minerals, Falconbridge, Ontario. The modern froth flotation process was independently invented the early 1900s in Australia by C.V Potter and around the same time by G. D. Delprat. Copper sulfide loaded air bubbles on a Jameson Cell at the flotation plant of the Prominent Hill mine in South Australia. All primary sulfide ores of ...

Key words: Nickel (Ni), Copper (Cu) recovery, BCL Abstract BCL operates a conventional three-stage base metal concentrator to treat run-of-mine (ROM) nickel (Ni) and copper (Cu) ore. Currently, approximately 3 million tonnes of ROM is processed annually at head grades of about 0.71% Ni and 0.65% Cu to produce about four hundred and fifty thousand (450K) tonnes of Ni/Cu concentrate

The final Cu/Ni separation flowsheet was assessed in locked cycle flotation testing and the Cu/Ni locked cycle test demonstrated substantial copper / nickel separability. An extended 10-cycle test showed good stability within three cycles, allowing reliable metal split factors to be collected over seven test cycles. The test produced a Cu concentrate assaying 13.8% Cu, which contained 52.2% of ...
There is provided a process for the recovery of nickel and cobalt values from a sulfidic flotation concentrate. The process involves forming a slurry of the flotation concentrate in a sulfuric acid solution, and subjecting the slurried flotation concentrate to a chlorine leach at atmospheric pressure followed by an oxidative pressure leach at elevated temperature under acidic conditions.
