  • Nickel Mining and Processing: Everything you Need to Know

    Although nickel is documented being used as far back as 3500 BC by Syrians who used a small amount and in 235 BC by the Chinese who minted coins from nickel, nickel mining itself is relatively new compared to other mined materials. Dating back to 17th century Germany, nickel was discovered in a red-colored ore that German miners believed was copper. When their analyzation revealed it to be ...

    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: 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.

    New Caledonia has the longest history of mining in the Pacific islands. Nickel was found in New Caledonia in 1864 by the engineer Jules Garnier. It was distributed in the ore layers which cover about one third of the area of the main island of New Caledonia. The nickel concentration was inhomogeneous and also varied with the depth. Whereas its usual concentration was 2–5 percent, it could reach 10–15 percent in scattered deposits of green garnierite. Those areas were developed first using primitive man

    Nickel laterites are a very important type of nickel ore deposit. They are growing to become the most important source of nickel metal for world demand (currently second to sulfide nickel ore deposits). Nickel laterites are generally mined via open cut mining methods. Nickel is extracted from the ore by a variety of process routes. Hydrometallurgical processes include high-pressure acid leach (HPAL) and heap leach, both of which are generally followed by solvent extraction - electrowinning (SX-EW) for rec

  • Nickel Geoscience Australia

    After mining, nickel ores are further processed to upgrade their nickel contents from 1-4% typical of the ores to concentrates with grades in the range 10-20%. Concentration involves crushing the ore and separating nickel-bearing from other minerals using various physical and chemical processing methods. The concentrates are then smelted (in a furnace) to produce a sulfide ‘matte’ with up ...
