Nickel element extraction, mining technique – flash,
The mining methods differ with respect to the type of ore being mined. Since nickel is composed in two types of ores, both of them are mined differently. The sulfide ores are mined using underground mining methods though open-pit mining can also be done in early stages. The laterite ores are mined through applying earth-moving operation techniques.

Nickel Ore - an overview | ScienceDirect Topics
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 ore.

Nickel mining in Australia – history, top locations and,
15-02-2021· 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%.
Copper-Nickel ores - Danafloat

Geology and mining — MineFacts
The choice of mining method is made after consideration of a number of parameters, such as the placing of the ore body, the geology, geometry, rock mechanical conditions and the environment and surroundings. The form and appearance of the ore, which becomes apparent through prospecting, is of vital importance when selecting a mining method.

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.
