2020-8-17  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

Nickel mining in Australia history, top locations and

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%.
