Jul 28, 2019· Sulfide ores can be separated using froth flotation and hydrometallurgical or magnetic processes to create nickel matte and nickel oxide. These intermediate products, which usually contain 40-70% nickel, are then further processed, often using the Sherritt-Gordon Process.

Nickel and Cobalt | Solvay

In hydrometallurgical processes, nickel sulfide ores undergo flotation (differential flotation if Ni/Fe ratio is too low) and then smelted. After producing the nickel matte, further processing is done via the Sherritt-Gordon process. First, copper is removed by adding hydrogen sulfide, leaving a concentrate of only cobalt and nickel. Then ...

A Comparative Study of Kinetics of Flotation of a Copper ...

2. 2. Flotation Procedure 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

Copper-Nickel ores

1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air …

Advanced flotation process control system at a base metal ...

The optimum nickel and pentlandite recovery was achieved at particle size of 64.73 µm milled for 1.5 h, pH of 9.65 and using a new flotation cell. Also, collector recovered more nickel and pentlandite contents compared to PAX and SIBX collectors when optimum parameters of particle size, milling time, pH and flotation cell were considered.

1 Froth Flotation – Fundamental Principles

In the flotation of coarse fractions, the addition of copper sulphate depressed nickel flotation without affecting gangue entrainment. However, when samples were collected directly from the plant streams and floated in a laboratory flotation cell, the addition of copper sulphate increased nickel recovery without affecting gangue entrainment in ...

Nickel flotation for High Talc Ores - Strategic Met

copper-nickel sulphide ores is stage-wise flotation. The first flotation stage concentrates mainly copper minerals. The copper middling is re-floated to obtain nickel concentrate. During the industrial process of copper-nickel ore, it was observed that significant amount of nickel sulphides was lost to the tailings during the nickel flotation.

The Application of High Intensity Flotation Technology at ...

The nonferrous metal chlorides may then be water leached, separated, purified, and electrolyzed to recover copper and nickel metals and to regenerate chlorine for recycling. AB - A chlorination process for treating metal sulfide flotation concentrates is described.

A Comparative Study of Kinetics of Flotation of a Copper ...

Nickel processing - Nickel processing - Extraction and refining: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel ...

result in nickel losses into the tailings. This problem can be overcome by using depressants like car-boxymethylcellulose (CMC) and guargum deriva-tives, although their cost accounts for as much as 60% of the reagent cost incurred in the plant. Developments in Flotation Flotation of Nickel Sulde Minerals

and nickel, PAX collector was suggested for further experiments due to its long chain and ability to promote the recoveries of copper and nickel which are asso-ciated with chalcopyrite, pyrrhotite and pentlandite. 3.1.2. Effect of Collector Dosage Flotation behavior of copper and nickel from mine tailing was investigated un-

Process flowsheet development for beneficiation of nickel ore

AEROPHINE®, AERO® and AEROFLOAT® collectors (promoters) are used extensively for the flotation of sulfide minerals including copper, gold, lead, zinc, nickel, iron and many others, such as lithium. These products provide improved performance and higher selectivity than more traditional sulfide collectors and better overall metallurgical ...

NICKEL AND COBALT ORES: FLOTATION

Solvay offers a variety of unique solutions for nickel and cobalt processing. Flotation. Flotation reagents from our AERO®, AEROFLOAT® and OREPREP® brands enable the recovery of sulfide nickel/cobalt minerals from ore. AERO polymeric depressants, such as AERO 7261A, help in making a clean separation by depressing non-value sulfide minerals.

2019 New Product Nickel Ore Flotation Machine,Molybdenum ...

Flotation of nickel from this ore [3] is quite difficult and requires very high collector additions. In contrast, nickel flotation from massive ores, such as Voisey Bay (Canada) requires very little collector [4] due to the fact that nickel-bearing minerals are relatively floatable.

(PDF) Flotation of Nickel-Copper Sulphide Ore ...

Copper-nickel sulfide ore beneficiation methods: The most important is the flotation. The magnetic and the gravity separation is usually secondary dressing method. Flotation copper sulfide nickel ore: often used in the flotation of copper sulphide minerals collector and frother. Application

Nickel processing | Britannica

Flotation kinetics was studied for the flotation of Canadian nickel ore using N-hydrocinnamoyl-N-phenylhydroxylamine (HCNPHA) as the collector. The differential flotation between pentlandite and pyrrhotite of HCNPHA was compared by repeating the experiments with potassium amyl xanthate (PAX).

Potential Use of Oxygen Depleted Air In Nickel Sulphide ...

Most of the world's nickel is extracted from the mineral pentlandite, (Ni, Fe)9S8, which frequently occurs in ores containing predominantly pyrrhotite and various non-sulRdes, some of which contain magnesium (Table 1). The nickel content in such sulRde ores is generally low (0.2}3%) and varies from place to place in the same deposit. The low nickel content of the present-day nickel sulRde ...
