Nickel

Overview

Nickel is a silverywhite 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 355 176;C (671 176;F), meaning that bulk nickel is nonmagnetic above this temperature. The unit cell of nickel is a facecentered cube with the lattice parameter of 0.352 nm, giving an atomic radiusof 0.124 nm. This crystal structure is stable to pressures of at least 70 GPa. Nickel belongs to th

Flotation reagents from our AERO174;, AEROFLOAT174; and OREPREP174; 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 nonvalue sulfide minerals.

Nickel processing Britannica

The nickel content of laterites varies widely at Le Nickel in New Caledonia, for example, the ore delivered to the smelter in 1900 contained 9 percent nickel; currently it contains 1 to 3 percent. Mining. With nickel found in two radically different types of ore, it is not surprising that the mining methods differ.

CopperNickel Studies and Nonferrous Mining Minnesota

Minnesota Issues Resource Guides CopperNickel Studies and Nonferrous Mining. This guide is compiled by staff at the Minnesota Legislative Reference Library on a topic of interest to state legislators. It introduces the topic and points to sources for further research. It is not intended to be exhaustive.

What Is Nickel Smelting? (with picture)

Feb 13, 20200183;32;Nickel smelting is the process that nickel ore goes through to eventually remove impurities and leave just the nickel metal. While the ores can come from different stones and sources, they have two categories lateritic, or rocks found in tropical climates and which contain nickel; and sulfidic ore, which is mined from underground.

Nickel processing Extraction and refining Britannica

Being free of sulfur, laterite nickel deposits do not cause a pollution problem as do the sulfide ores, but they do require substantial energy input, and their mining can have a detrimental effect on the environment (e.g., soil erosion). The range of process options is limited by the nature of the ore.

Nickel mining in New Caledonia

Nickel mining in New Caledonia is a major sector of the New Caledonian economy. The islands contain about 7,100,000 tonnes of nickel which is about 10% of the world's nickel reserves. With the annual production of about 107,000 tonnes in 2009, New Caledonia was the world's fifth largest producer after Russia (266,000), Indonesia (189,000), Canada (181,000) and Australia (167,000).

Gold, nickel and copper mining and processing.

This chapter examines cancer risk related to the mining of gold, nickel and copper. The human carcinogenicity of nickel depends upon the species of nickel, its concentration and the route of exposure. Exposure to nickel or nickel compounds via routes other than inhalation has not been shown to increase cancer risk in humans.

Copper recovery from nickel laterite with highiron

The waste product from the hydrometallurgical processing of nickel laterite ores can contain valuable metals, making their recovery economically viable. However, the highimpurities content, mainly iron, makes the process technically unfeasible. As a result, the separation of metals from the leach solution must be selective.
