Commodity Nickel - Everything you need to know about Nickel

Nickel was discovered by Axel von Cronstedt, who believed he was extracting copper but instead found a silver-white metal which he named nickel. Initially nickel could only be extracted from the very rare Kupfernickel but later on it would be obtained as a by-product from cobalt blue production.

Environmental Impacts of Nickel Mining and Processing ...

Nickel deposits are typically found in low-grade ores (~1-2% nickel) thus making it highly energy intensive to extract and refine the metal. This leads to high emissions of greenhouse gases into the atmosphere and the use of large amounts of energy derived predominantly from fossil fuels ( 2 ).

How do we extract minerals? - USGS

The primary methods used to extract minerals from the ground are: Underground miningSurface (open pit) miningPlacer mining The location and shape of the deposit, strength of the rock, ore grade, mining costs, and current market price of the commodity are some of the determining factors for selecting which mining method to use.

Mond process - Wikipedia

The Mond process, sometimes known as the carbonyl process, is a technique created by Ludwig Mond in 1890, to extract and purify nickel.The process was used commercially before the end of the 19th century, and particularly by the International Nickel Company in the Sudbury Basin. This process converts nickel oxides into nickel metal with very high purity being attainable in just a single step.

Nickel Ore - an overview | ScienceDirect Topics

Scrubbing is the chemical removal of nickel that has co-extracted with the cobalt. Solvent extraction does not remove impurities, for example, iron, arsenic, lead, manganese and calcium. Solvent extraction is used to extract cobalt from the leaching solution into an organic extractant, leaving a nickel-rich, cobalt-lean electrolyte.

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.
