Nickel: smelting, producing-Metalpedia
Nickel: smelting; Extraction and purification; Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel applications, 75% pure nickel can be used without further purification, depending on the composition of the impurities.

What Is Nickel Smelting? (with picture) - wiseGEEK
2-5-2020 · 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 mining in New Caledonia - Wikipedia
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 worlds nickel reserves. With the annual production of about 107,000 tonnes in 2009, New Caledonia was the worlds fifth largest producer after Russia (266,000), Indonesia (189,000), Canada (181,000) and Australia (167,000).
Nickel - Wikipedia
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 ...
