A low grade disseminated nickel sulphide serpentinite ore from W A had a relatively high permeability after drying Various techniques indicated that the permeability resided within a fine network of fibrous vein lets and especially within coarse cracks along which the sulphides lay The ore minerals were therefore open to selective extraction by chemical leaching.

Processing Oxidised Nickel Ore With Flotation Processing Oxidised Nickel Ore With Flotation Impact of oxidation on flotation of Ni–Cu sulphide ore with respect to Impact of oxidation on the flotation of a complex Ni–Cu sulphide has been for the best papers published in.
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.
Collectors and foamers are often used for flotation of copper sulfide ores A basic principle for determining flotation process is that copper can enter nickel concentrate rather than nickel Because the nickel in the copper concentrate is lost greatly in the smelting process and the copper in the nickel concentrate can be recovered completely.
Nickel Sulphide Flotation From Serpentine MgO Depression in Ci Ni Flotation Froth Flotation Froth Flotation Sulphide amp Oxide Talc or other mineral such as serpentine of course makes a huge difference to the adopted strategy Guar gum of course is well known talc depressant.
Within 3 min During the flotation the concentration was collected after cumulative times of 2 4 6 8 and 10 min To investigate how the flotation was affected by the pulp density of a single mineral and the mixture of sulfide and serpentine sulfide and serpentine slurries (5 40 wt of the total solid by.

Commercial flotation process for mineral beneficiation at the Froth flotation cells to concentrate copper and nickel sulfide Before froth flotation can work Aguablanca Mine Lundin Mining Effects and Researching Developments of Serpentine on the.
The artificial mixed mineral flotation results (with 10 μm serpentine) showed that with the conditioning time extended from 60 s to 360 s a large amount of Mg 2+ on the mineral surface gradually dissolved into the pulp resulting in a decrease of brucite recovery (from 83 83 to 76 79 ) whereas the recovery of serpentine increased from 52.
Addition on flotation performance of a nickel sulphide ore The objectives of the study were to 1 develop an understanding of the effects of collector and depressant dosage and its interactive effects on flotation performance and 2 determine the effect of stage dosing collector and depressant on flotation.
Oct 12 2016 In this study citric acid was used as a dispersant to improve the flotation performance of hematite fines The effect and mechanism of citric acid on the reverse flotation of hematite fines were investigated by flotation tests sedimentation experiments scanning electron microscopy (SEM) zeta potential measurements and X ray photoelectron spectroscopy (XPS).
The method of flotation of sulfide copper Nickel ores including grinding and conditioning of the ore in the presence of sulfhydryl collector dithiocarbonate the introduction of the first stage of flotation oil soluble sulfonates of alkaline earth metals and of the expander and stepwise selection of sulfide mniam to the first stage of.
1 Types of copper sulfide ore (1) Single copper mineral Its ore characteristic is relatively simple and the only useful component that can be recycled is copper The gangue minerals are mainly quartz carbonate and silicate (2) Copper sulfur ore Called copper bearing pyrite In addition to copper minerals iron sulfide can be recovered and the main mineral of sulfur is pyrite.
Nickel Ore Gravity Concentration Plant Hsdsj Nickel Ore By Gravity Concentration Nickel ore by gravity concentrationickel ore processing yantai jinpeng mining equipment ickel ore divides into copper sulfide and copper oxide ore the main process for copper sulfide is flotation magnetic and gravity separation is the subsidiary process is a high technological enterprise that.
Jan 06 2016 Nickel ore dispersion before flotation using different reagents was investigated on a bench scale to improve metallurgical recovery and selectivity The nickel ore had a content of 0 8 pct nickel and 14 5 pct MgO A positive linear correlation between MgO and Ni was found Carboxy methyl cellulose both pure and combined with Na2CO3 was the best dispersant used.
A process for floating fine particles containing metal values of an iron bearing sulphide mineral ore including the steps of conditioning the aqueous pulp of ore at a pH of between about 7 and about 10 with a reducing agent which is preferably oxy sulphur compound which dissociates to form oxy sulphur ions having the general formula S n O y z− where n is greater than 1 y is greater than 2.
Other magnesium silicates such as serpentine carry nickel in solid solution limiting the recovery entitlement of nickel by flotation because serpentine is not amenable to sulfide flotation mechanisms Differences in plant flow sheets and reagent assemblages are required to effectively separate these minerals Experience from a variety of plant.
Separation of serpentine from sulfide ore in the flotation of the serpentine bearing sulfide ore especially in the flotation of the copper nickel sulfide The main gangue mineral has a much higher content of serpentine and it is prone to being clayed which seriously interferes with the flotation of nickel containing minerals[1−8] In order.
Abstract—This study investigated the effect of oxygen and micro cracking on the flotation of low grade nickel sulphide ore The ore treated contained serpentine minerals which have a history of being difficult to process efficiently The use of oxygen as a bubbling gas has been noted to be effective because it increases the pulp potential.
