Copper Nickel Ore Flotation Process: A basic principle of coppersulfide 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 advantageget the copper concentrate that has a low nickel
Nov 14, 2007 · Due to the complex structure of mineralization, a combination of gravityseparation and flotation methods was applied for the concentration of nickel sulphide and oxide ores. A nickel concentrate containing 12.32% Ni was produced with 89.7% recovery and final tailings with 0.088% Ni can be disposed with 4.9% of metal loss.
Some plants use bulk flotation in an acid pH environment which is achieved using SO2 or H2SO4. Separation of the bulk concentrate copper and nickel minerals is generally accomplished by flotation of the copper from pentlandite and nickelbearing iron sulphides which report to the flotation tails.
Developments in Flotation Flotation of Nickel Sulde Minerals Collectorless Wotation It is known that chalcopyrite and pyrrhotite can be Soated without collectors III/NICKEL AND COBALT ORES: FLOTATION 3493. Figure 5 Flotation selectivity in the separation of pentlandite
Nickel sulphide ores containing pentlandite, pyrrhotite and talc have traditionally been treated by bulk sulphide flotation, an approach which seeks to maximise nickel recovery and talc rejection but which does not reject pyrrhotite.
nickel flotation machine flotation machine for ore flotation Froth flotation circuit design and basic testwork requirements News. Froth flotation is a mineral concentration process used to recover a vast array of different lead, zinc, nickel, molybdenum, tungsten, silver, gold, phosphate and potash.
Nickel Ore Processing. Nickel ore mainly consists of coppernickel sulfide ore and nickel oxide ore, beneficiation and processing of both methods is completely different. Coppernickel sulfide ore beneficiation methods, the most important is the flotation, magnetic and reelection is usually secondary dressing method.
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
FIG. 4 c is a graph plotting nickel grade against pentlandite recovery during flotation of a Sudbury area ore when both TETA/sulfite and MM are added. DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the process of the present invention for depressing arsenide in ore comprises the following steps.
Nickel processing, preparation of the metal for use in various products. Although it is best known for its use in coinage, nickel (Ni) has become much more important for its many industrial appliions, which owe their importance to a unique combination of properties. Nickel has a relatively high
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 0.35 pct Cu and 0.11 pct Ni and the shaft sample analyzed 0.69
A sequential flotation process for the recovery of highgrade concentrates of copper, lead and cobaltnickel 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 tailings from these cells is sent to another flotation cell, to recover the nickel, and the concentrate is combined with the 3% nickel concentrate to produce a 12% nickel concentrate. Most nickel ores have several recoverable metals in them and the process if commonly a multiple stream of metals recovered. The copper concentrate is sent to
The reagent practice in the flotation of nickel and copper–nickel ores depends on three basic factors: mineralogy of the ore, flowsheet employed in the treatment of a specific ore, and degree of liberation. The presence of hydrophobic gangue represents a major problem in the treatment of both nickel and copper–nickel ores.
Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel appliions, 75% pure nickel can be used without further purifiion, depending on
The invention relates to the enrichment of ores of nonferrous metals and can be used in the beneficiation of sulfide copperNickel ores. Known to be used as collectors in flotation of sulfide copperNickel ores amyl, isopropyl, isobutyl, ethyl and butyl of xanthates and Aeroflot, secondary butyl xanthate and derivatives mercaptobenzothiazoles

Apr 24, 2010 · In many stainless steel appliions, 75% pure nickel can be used without further purifiion depending on the composition of the impurities. Nickel sulfide ores undergo flotation (differential flotation if Ni/Fe ratio is too low) and then are smelted. After producing the nickel matte, further processing is done via the SherrittGordon process.
There are more than 45 different nickel minerals, but only a few are of economic importance. Table 16.1 lists some of the most important nickel minerals. Nickel, in various ores can also be found in other minerals, such as pyrrhotite and various cobalt minerals as an exsolution in isomorphic phases
The nickel grade of the ore sample used in this study was 1.35%. Approximately 96% of the nickel in the ore was in the form of pentlandite, and could be recovered by true flotation. The remaining 4% of nickel distributed in nonsulfide minerals, which could only be recovered by the entrainment mechanism or as composites with pentlandite.
(57) Abstract: The invention relates to the enrichment process, in particular to flotation separation methods of the minerals copper, Nickel and waste rock, forming part of cuprous ores with complex mineralization, highly developed border sulfide and nonmetallic minerals and the most rebellious in comparison with other types of copperNickel ores.
Froth flotation is considered to be the most widely used method for ore beneficiation. In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer.
Copper Nickel Flotation. 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.
Flotation of low grade nickel sulfide ores into a concentrate suitable for smelting, and at acceptable nickel recovery, can be challenging. Alteration of the gangue minerals can mean talc is present in considerable quantities. Talc floats naturally and can be very difficult to depress without significant nickel
A flotation separation test was carried out in the conventional manner on a coppernickel ore from the Sudbury region (Canada), containing 16.8% pyrrhotite, 1.5% copper and 1.6% nickel. The ore was ground to a fineness of 55% passing 200 mesh Tyler sieve and

With the BCL SelebiPhikwe ore body, pentlandite–pyrrhotite–chalcopyrite cooccur and there is the constraint of fine pentlandite dissemination in the pyrrhotite, so that liberation is limited.
Nickeline or niccolite is a mineral consisting of nickel arsenide (NiAs) containing 43.9% nickel and 56.1% arsenic.. Small quantities of sulfur, iron and cobalt are usually present, and sometimes the arsenic is largely replaced by antimony.This last forms an isomorphous series with breithauptite (nickel
