magnetic separation of nickel

The magnetic separation was investigated for Co2+ (9500 × 10-6 cm3 mol-1) and Fe3+ (14600 × 10-6 cm3 mol-1) ions and for Cr3+ (6200 × 10-6 cm3 mol-1) and Al3+ (−2 × 10-6 cm3 mol-1) ions. The metal ion solutions were spotted on a silica gel support, and exposed to a magnetic field of 410 kOe2 cm-1 intensity × gradient. The Co2+ ions move farther toward the maximum field than the Fe3+ ions.

Efficient magnetic separation offseted the poor settleability and filterability of the precipitate. After magnetic separation of iron residue, the nickel solution was qualified and the dried iron residue contained more than 52% Fe and less than 0.6% Ni, indicating a promising alternative process for treatment of bulky residues of iron precipitate.

magnetic separation of nickel - … Magnetic separation of iron precipitate from nickel. After magnetic separation of iron residue, the nickel solution was qualified and the dried iron residue contained more than 52% Fe and less than 0.6% Ni, indicating a promising alternative process for treatment of bulky residues of iron precipitate.

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 applications, which owe their importance to a unique combination of properties. Nickel has a relatively high

Coal-based direct reduction of nickel slag and magnetic separation of iron are effective methods of secondary resource utilization. The growth characteristics of metallic iron particles in this process are of great significance for subsequent grinding and magnetic separation process. The nickel slag is mixed with coal powder and other additives in a certain proportion, and then subjected to a ...

Magnetic separation has some limitations. It cannot separate iron and steel from nickel and magnetic stainless steels. Also, composite parts containing iron will be collected which could contaminate the melt. Hand sorting may be used in conjunction with magnetic separation to avoid these occurrences.

Nickel Ore Processing. Nickel ore mainly consists of copper-nickel sulfide ore and nickel oxide ore, beneficiation and processing of both methods is completely different. Copper-nickel sulfide ore beneficiation methods, the most important is the flotation, magnetic and re-election is usually secondary dressing method.

The process of deep reduction and magnetic separation was proposed to enrich nickel and iron from laterite nickel ores. Results show that nickel–iron concentrates with nickel grade of 6.96%, nickel recovery of 94.06%, iron grade of 34.74%, and iron recovery of 80.44% could be obtained after magnetic separation under the conditions of reduction temperature of 1275 °C, reduction time of 50 ...

This number will change as the magnet is integrated into a piece of separation equipment. By manipulating the north and south magnetic poles on the magnets thru placement and the use of steel pole pieces or back plates, the magnetic field is enhanced and directed into the product flow area for optimum separation.

Starting with a mixture of any of the above minerals it may be determined whether or not they can be separated by high tension, magnetic, or gravity methods and whether any one, or a combination of “Electromagnetic Separation” methods is required.If the minerals appear in different columns they may be separated by high tension and/or magnetic methods alone.

Eriez High Intensity Magnetic Filters. The magnetic collection of fine particles requires a high-intensity, high-gradient magnetic field. An electromagnetic matrix-type separator, referred to as a magnet filter, has proven to be the most effective method of separation.

Magnetic separation of nickel ore. Nickel is silvery white metal, because of its good mechanical strength and ductility, refractory high temperature resistance, and has the very high chemical stability, no oxidation in the air and other feature. Therefore, it is very important non-ferrous metal raw material, is used in the manufacture of stainless steel, high nickel alloy steel and alloy ...

quantity of slag produced per year, the recovery of nickel from the EAF slag will add benefits to the entire process. The target of the current work is to investigate the possibility of nickel recovery from EAF slag by magnetic separation.

Magnetism is a class of physical phenomena that are mediated by magnetic fields. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments. Magnetism is one aspect of the combined phenomenon of electromagnetism.

§ 4.2.1 Magnetic Separation of Free Metals. As discussed in the section on asteroid resources, asteroids are rich in free nickel-iron metal granules. The Moon has trace but extractable quantities of these granules as well, left over from asteroid impacts and preserved on the waterless, rustless Moon.

Is Nickel Magnetic? The element Nickel (Ni) is one of the few ferromagnetic metals. Ferromagnetic means they are attracted to magnets and can be magnetized themselves. Most metals aren’t magnetic with the exception of iron, nickel, cobalt, gadolinium, neodymium and samarium.

Mar 20, 2014· MAGNETIC SEPARATION:This is based on differences in magnetic properties of the ore components. If the ore particles are magnetic and the non-magnetic material is gaungethis method is used.
