Copper-Nickel ores
Copper-Nickel ores. Pentlandite ( (Ni,Fe)S) is the most important nickel sulphide mineral and is often associated with nickel-containing pyrrhotite and chalcopyrite. Gangue minerals can include talc and other troublesome silicates which must be dispersed and/or depressed. Recovery and separation entails floating all three sulphide minerals into a bulk flotation concentrate at …

copper and nickel flotation equipment. mineral separator nickle flotation machine,Laboratory Copper Nickel Ore Flotation mill at 60 pct solids and flotation was carried out in a standard laboratory flotation cell at about 30 pct solids Primary separation products of the pit sample were a rougher flotation...
Flotation of Nickel-Copper Sulphide Ore: Optimisation of ...
All the flotation test-work was done using the Denver laboratory machine with a 1.5l stainless steel flotation cell. The required mass of nickel-copper 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
Lime in Flotation and Recovery Processes | Graymont
Lime in Flotation and Recovery Processes. Both quicklime and hydrated lime are widely used in the flotation or recovery of non-ferrous metals, including copper, zinc, nickel and lead-bearing ores. Lime is used extensively in the recovery of gold and silver. Ores, either run-of-mine, milled, autoclaved or roasted, are combined with lime and a cyanide solution.
(PDF) A Review of the Flotation of Copper Minerals
Oxidic ore can be concentrated using flotation or, if it has a low acid demand, it may be economic to acid heap leach the stockpile. The recovery of these copper minerals by flotation or...

Nickel processing - The metal and its alloys | Britannica
Copper-nickel. The addition of copper to nickel provides a series of useful alloys. Monel metal, 67 percent nickel and the balance essentially copper, is stronger than nickel and has broad corrosion-resisting applications. Extremely resistant to rapidly flowing seawater, it …
Copper Sulphide Ore Reagents For Copper Flotation
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.
Nickel Ore Mineral Processing
Copper- Nickel Ore Flotation Process: A basic principle of copper-sulfide nickel ore process is that it is better to let the coppers assimilate into the nickel ore. Because it is easier to recovery cooper from the nickel concentrate. The process has a best advantage-get the copper concentrate that has a low nickel rate directly.
The effect of copper sulphate addition on the recovery of ...
Due to the natural pH of PGM ores in the Bushveld Complex, the copper hydroxyl species present at pH 9 can cause unselective and inadvertent activation, which, with subsequent addition of collectors, can lead to true flotation as has been observed in other systems (Nagaraj and Brinen, 1995; Fuerstenau et al. 1970).
CHLORINATION OF COPPER AND NICKEL SULFIDE …
The process involves low temperature chlorination combined with sulfur chloride conversion and selective oxidation to produce nonferrous metal chlorides, elemental sulfur, and ferric oxide in a three-stage fluidized bed reactor. The nonferrous metal chlorides may then be water leached, separated, purified, and electrolyzed to recover copper and nickel metals and to regenerate …
Sulfide Ores - an overview | ScienceDirect Topics
Copper sulfide ores must be concentrated before they can be economically transported and smelted. The universal technique for this concentration is froth flotation of finely ground ore. Froth flotation entails attaching fine Cu-sulfide mineral particles to bubbles and floating them out of a water–ore mixture.
