Separation of Co(II) and Ni(II) from chloride leach solution of nickel
Section snippets Preparation of the feed solution. The chloride leach liquor of laterite ore contained large amounts of ferrous iron (90 g/L) together with cobalt, nickel, magnesium, manganese, calcium and aluminum.The pH of this leach liquor is about − 0.5.This ferrous iron was completely removed by solvent extraction with mixture of To increase the efficiency of magnetic separation, a large particle size of ferronickel is desired. Therefore, in this study Evolution of ferronickel particles during the reduction of low-grade saprolitic laterite nickel ore by coal in the temperature range of 900–1250°C with the addition of CaO–CaF 2 –H 3 BO 3, Int.

An Overview of Nickel Utilization from Laterite Ore
The nickel–cobalt alloy is a kind of permanent magnetic material and is widely used in the field of electronic remote control, atomic energy industry and ultrasonic technology [ 6, 7, 8 ]. Besides, in chemical industry, nickel and its alloys are usually used as catalysts for hydrogenation reactions. Fig. 1.1.In order to separate Ni(II) and Co(II) from the chloride leaching solution of nickel laterite ore, solvent extraction experiments with the mixtures of organophosphorus extractants and LIX63 were performed in the pH range from 1 to 3. Among the studied mixtures, a mixture of D2EHPA and LIX63 with the molar ratio of 3:7 showed the best Separation of Co and Ni from a chloride leach solutions of laterite ore

Separation and Recovery of Iron and Nickel from Low-Grade
Nickel and iron recoveries were 96.72 and 89.08% respectively, which achieved the highly efficient recovery and utilization of iron and nickel from low-grade laterite nickel ore. The low-grade nickel laterite ore used in this study was successfully upgraded through selective reduction by industrialized rotary kilns followed by magnetic Introduction. To date, preconcentration of complex, low grade Ni laterite ores poses considerable challenges. In our previous paper (Quast et al., 2015) a review of publically available literature concerning a number of physical separation techniques for the preconcentration of Ni laterite ores that had been tested at laboratory or pilot plant scale, Preconcentration strategies in the processing of nickel laterite ores

Recovery of Valuable Metals from Nickel Smelting Slag Based on
Nickel smelting slag contains valuable metals including nickel and copper. Failure to recycle these metals wastes resources, and disposal of nickel slag in stockpiles results in environmental pollution. Nickel slag recycling is important, and metals can be recovered from slag by flotation. However, considering the complex forms in which Magnetic separation of slag milled to a diameter of 0.16 mm revealed that the content of magnetic phase was 10–20%, consisting of nickel, iron, chromium, etc. Nickel was present at the same level in both separation products, and the magnetic separation products had an iron content of 11–16%.Recycling of Nickel-Slag Tailings into Liquid Products: A Case

A Review of Nickel, Copper, and Cobalt Recovery by Chelating Ion
Copper and cobalt can be found on nickel laterite ores, and cobalt can be found also on copper ores, and many contaminants such as iron, aluminum, and magnesium are associated with these ores. In hydrometallurgical process, a purification step is necessary after leaching due to the presence of these impurities. Chelating resins A characteristic feature of serpentine oxidized nickel ores (ONO) of the Serov deposit (≈ 1 wt.% Ni) is the increased content of iron and magnesium. The main nickel-containing phases are lizardite, antigorite, clinochlore and iron oxides with the nickel content varying from 1.6 to 9.2 wt.%.Heap (percolation) leaching with aqueous H2SO4 Extraction of Nickel from Oxidized Nickel Ores by Heap Leaching

Selective extraction and separation of nickel from cobalt,
Introduction. Resource quality and economic treatment of low grade ores can be challenging for producers in mining and metallurgical industry. Global nickel and cobalt reserves are distributed in nickel–iron–copper (Ni–Fe–Cu) sulfide ores and nickel laterites (30% and 70%, respectively).The production of ferronickel concentrate from low-grade nickel laterite ore containing 1.31% nickel (Ni) was studied by the non-melting reduction magnetic separation process. The sodium chloride was used as additive and coal as a reductant.

The selective chlorination of nickel and copper from low-grade nickel
The orthogonal experiments results showed that the optimal conditions of the chlorination roasting process were the roasting time of 3 h, the roasting temperature of 450 °C, the mass ratio of AlCl 3 to ore of 1.5:1, the content of O 2 of 20%, and particle size of the ore of 96–80 μm, under this condition, an extraction rate of nickel, copper, iron, As a consequence, the separation of nickel from cobalt is a significant challenge for hydrometallurgists. Nickel laterite ore is typically processed by variations of two flowsheets; ammonia leaching of roasted ore, or direct sulphuric acid leaching, with industry favouring the latter in recent times.Selective leaching of nickel from mixed nickel cobalt hydroxide
