Apr 01 1999 This polymer was successfully used as pyrrhotite depressant during copper-nickel bulk flotation. Cationic polymers The most important groups of the cationic polymers that are used in mineral flotation include a ethylenediamine with the formula shown in Figure 14. H2N - C2H4 - NH2 Fig. 14 Ethylenediamine.
Nickel Ore Processing Highmetals KDS Technologies. For the Copper-nickel sulfide ores the main beneficiation method is flotation..
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.
gangue minerals thus leading to nickel loss. Flotation Practice in Nickel Sulde 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.
Case Study Savannah Mine Nickel Flotation With Pyrrhotite Gangue We tested a nickel sulfide ore from the Savannah mine with an on-site laboratory flotation cell. The standard flotation reagent suite was compared with the addition of 300 gpt of Pionera F-300 and an additional aeration step in a rougher flotation setting.
Sep 24 2020 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.
Jan 07 2020 2. Bulk flotation process. Bulk flotation process is used to separate ores containing less copper than nickel and the copper-nickel mixed concentrate can be directly smelted into high-ice nickel. 3. Bulk-differential flotation process. The copper and nickel are separated from the ore and then the mixed concentrate is separated as the copper.
The flotation response of gersdorffite has been determined in a series of batch flotation tests in which a sulphide sample containing about 76 gersdorffite was floated from mixtures with quartz.
An experimental technique for the differential flotation of bulk sulfide concentrates from Duluth Gabbro into copper and nickel concentrates is described. The technique utilizes a two-stage bulk sulfide flotation procedure to obtain a copper concentrate that analyzed 25 percent copper and 0.5 percent nickel and a nickel concentrate that analyzed 10 percent nickel and about 1 percent copper.
Bulk sulfide flotation for further treatment ultrafine grinding UFG or preoxidation. Table 2 shows the elemental compositions of the bore water used in the Mt Keith Operation the largest nickel flotation plant in Western Australia Peng and Seaman 2011. The salinity of this water is several times higher than that of sea water.
Nickel is the fifth most abundant element on Earth at an average bulk of 2.7. However the average nickel content of the crust is estimated at 0.008 percent. With such low content it makes it obvious why nickel mining is such an important industry and why recovery of nickel and nickel recycling is becoming increasingly significant in our.
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.
The flotation experiments were performed in a 0.5 L mineral separator MS type laboratory flotation cell to upgrade recoveries of Cu and Ni bulk flotation from mine tailing. In flotation tests an appropriate weight of the mine tailing sample was poured into 500 mL of water to prepare slurryfeed with different pulp densities from 10 to 25.

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.
Copper Nickel Bulk Flotation. Copper Nickel Pilot Plant Flotation Pilot plant flotation tests for both the pit sample and the shaft sample were done in the Bureaus TCRC flotation process demonstration plant Both samples were tested using flotation circuits that consisted of a rougher float followed by three cleaner floats plus a scavenger.
Froth flotation is a very important mineral concentration process that is used to recover a vast array of different minerals containing valuable commodities such as copper lead zinc nickel molybdenum tungsten silver gold phosphate and potash.
Differential flotation of bulk sulfide concentrates from Duluth gabbro into copper and nickel concentrates could be implemented by first destroying the hydrophobic coating with ozone and then by recovering the copper concentrate with a copper-selective collector. A number of parameters involved in the use of ozone such as the sequence and the conditioning time of ozone treatment the pulp pH.

Although pyrrhotite contains minor amounts of nickel and cobalt it represents the most important contribution to the iron and sulphide content of the flotation concentrate.
Usage mineral processing in particular flotation beneficiation of sulfide copper-Nickel ores containing platinum group metals. The technical result is an increase extraction of base and precious metals in bulk concentrate through the use of sulfhydryl collectors with enhanced flotation activity.
Jan 01 2018 The flotation circuit is designed with multiple stages consisting of bulk coppernickel flotation coppernickel separation and a separate nickel circuit bulk float and cleaning. Full Article Download 630 kb Additional chapters.
The latter may be problematic when intergrown inclusions of pentlandite or nickel in solid solution are present Rao 2000. Rejecting hexagonal pyrrhotite may be achieved by i staged flotation.
Dec 01 2013 The bulk sample was pulverized to −100 mesh and then split into 3 individual samples. Samples were prepared at two different levels of sulphur addition in order to assess the impact of bulk nickel sulphide grade on the flotation performance.
