Nickel processing Extraction and refining Britannica

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 production. The specific processes taken depend on whether the ore

Nickel processing Britannica

A new source, New Caledonia in the South Pacific, came into production about 1877 and dominated until the development of the copper-nickel ores of the Copper Cliff–Sudbury, Ontario, region in Canada, which after 1905 became the world’s largest source of nickel. By the late 1970s, production in Soviet Russia had exceeded that in Canada. By the early 21st century, China had become the world leader

Nickel Wikipedia

In hydrometallurgical processes, nickel sulfide ores are concentrated with flotation (differential flotation if Ni/Fe ratio is too low) and then smelted. The nickel matte is further processed with the Sherritt-Gordon process. First, copper is removed by adding hydrogen sulfide, leaving a concentrate of cobalt and nickel. Then, solvent extraction is used to separate the cobalt and nickel, with the final nickel content greater

Nickel Ore an overview ScienceDirect Topics

The smelting of ferronickel using lean nickel ores usually starts with roasting (calcining) of the ore mixture with limestone (~one third of the ore), anthracite (~1/10 of the ore amount), and recycled dust. Roasting is carried out in rotary kilns (~3 m in diameter, ~75 m in length, with a hot zone length of 9 to 12 m in the case of lean ore processing). The treatment temperature should not exceed 850°C to avoid stacking

Nickel Geoscience Australia

After mining, nickel ores are further processed to upgrade their nickel contents from 1-4% typical of the ores to concentrates with grades in the range 10-20%. Concentration involves crushing the ore and separating nickel-bearing from other minerals using various physical and chemical processing methods. The concentrates are then smelted (in a furnace) to produce a sulfide ‘matte’ with up to 70% Ni. The

The Direct Nickel Process :: Total Materia Article

Three primary processes are used to extract nickel from laterite ore. Conventional pre-concentration techniques are not feasible for nickel laterites as the majority of the nickel is distributed in the iron oxides and clays. This is different from the sulphide ores as the nickel occurs in a discrete mineral. The limonitic ores are processed using acid leaching (hydrometallurgical), the

Ore grade has a direct effect on mine investment costs expressed in US$ per annual tonne of nickel. Consider two identical ore bodies, one containing 1.25% Ni ore and the other containing 2.5% Ni ore. Achievement of an identical annual production of nickel in ferronickel requires that the 1.25% Ni ore be mined at twice the rate of the 2.5% Ni

Uses of Nickel Supply, Demand, Production, Resources

Nickel ore from the Sudbury Igneous Complex. The massive nickel ore consists of the minerals pentlandite and pyrrhotite, which surround fragments of igneous, sedimentary, and metamorphic rocks that were ripped from the walls of the crater by the impact of an extraterrestrial body.

Nickel is a silvery-white metal with a slight golden tinge that takes a high polish. It is one of only four elements that are magnetic at or near room temperature, the others being iron, cobalt and gadolinium.Its Curie temperature is 355 °C (671 °F), meaning that bulk nickel is non-magnetic above this temperature. The unit cell of nickel is a face-centered cube with the lattice parameter of
