Nickel Ore - an overview ScienceDirect Topics

Investment costs of mines vary considerably between mining operations. This is due to differences in ore grades, mine sizes, mining methods, topography and ground conditions. The costs for constructing an underground mine are considerably higher than those for constructing an open-pit mine, expressed per annual tonne of mined nickel.

2021-2-15  The rise in nickel mining is attributed to the Kambalda region in the Eastern Goldfields of Western Australia. Nickel ore grades in the 1960s had 4% nickel but within a decade the nickel ore grade in Australia fell to 2%. Over the last 20 years, low grade laterite or sulphide deposits have posted an average ore grade of about 1.2%.

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.

Processing of Nickel Laterite Ores on the Rise

The SX-EW Method. SX-EW, or the Solvent Extraction – Electrowinning approach to lateritic ore beneficiation, is a hydrometallurgical method that relies on leaching, extractants, and electrowinning to produce nickel from ore. This process is often referred to as Leach Solvent Extraction – Electrowinning for its employment of a leaching step.
