MINING AND PROCESSING : 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. Usage of large …

Nickel processing | Britannica

With nickel found in two radically different types of ore, it is not surprising that the mining methods differ. Sulfide deposits are usually mined by underground techniques in a manner similar to copper, although some deposits have been mined using open pits in the early stages. The mining of laterites is basically an earth-moving operation, with large shovels, draglines, or front-end loaders extracting the nickel-rich strata and discarding large boulders and waste material. The ore …

Lateritic nickel ore deposits - Wikipedia

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…

Hydrometallurgical processes include high-pressure acid leach (HPAL) and heap leach, both of which are generally followed by solvent extraction - electrowinning for recovery of nickel. Another hydrometallurgical routes is the Caron process, which consists of ...

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 ...

Raglan Nickel Copper Mine, Quebec - Mining …

Mining methods. Mining is predominantly conventional shovel-and-truck open pit with an underground mine at Katinniq. The first open pit mine in Zone 2, had a stripping ratio of 4:1 and benches in waste are 10m high while those in the ore are 5m high. Underground mining uses a single-pass mechanised cut-and-fill method in 8–10m-wide by 5m-high panels. Backfill is supplied from the open pits ...

01.10.2010· The extent of mining method and Australian average Ni ore grade are shown in Fig. 12, including economic resources over time. As can be observed, Australia's Ni resources continue to grow substantially, due to the progressive inclusion of low grade laterite ores in the 1990s. As noted by Schodde (2010), although there have been recent Ni sulfide discoveries, these effectively only replace …

How clean can the nickel industry become?

mining method, processing route, and type of generated waste will bring its own challenges for meeting ESG requirements. For smelters or refiners, the type of input material and the presence of impurities will determine the use of certain chemicals, and consequently emission of CO 2 and SO 2 gases. In general, three main aspects will be considered important by electric-vehicle (EV) OEMs: the ...

Nickel: smelting, producing-Metalpedia

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 …

06.09.2019· The ore is mixed with calcium oxide and silica, producing a slag. This makes it possible to separate silver, a mixture of materials rich in copper, nickel and cobalt and a scorifiable residue. This mixture rich in copper, nickel and cobalt is what is technically called “speiss”. Getting from this mixture to the pure metal is a complex process.
