Nickel is a hard silver-white metal with a high melting point and can withstand very low temperatures. Nickel is rarely found in the earth in its pure form; it mixes well with other metals to make many useful alloys. Nickel is malleable and ductile (can be beaten and drawn out into a wire) and is rust-resistant. Nickel is magnetic, although not as strongly as iron.

The size, grade, morphology and depth of the ore deposits determine whether they are mined by underground or open-pit methods. Lateritic nickel deposits are generally mined from open pits by strip mining, due to the shallow depth of most deposits and their clayey nature. The overburden is removed and generally deposited in the pit created from earlier mining.

Laterite-hosted nickel deposits form by the weathering of ultramafic rocks and are a near-surface phenomenon related to tropical climates. Although Australia holds large resources of lateritic nickel, very large deposits of this type also occur in Indonesia, New Caledonia, Philippines, Cuba and Brazil.

Nickel is not as well known as other metals but it plays an important, if invisible, role in modern life. When mixed with other metals nickel helps to create amazing alloys that are strong, won't rust, can withstand high and low temperatures and can be easily shaped into anything from thin wires to flat sheets. For example, nickel is one of the metals added to iron to make stainless steel - an extremely useful product. The Earth's magnetic field is due to the iron and nickel in its core.

Most mined nickel derives from two types of ore deposits that form in very different geological environments: magmatic sulfide deposits, where the principal ore mineral is pentlandite [(Ni,Fe)9S8], and laterites, where the principal ore minerals are nickeliferous limonite [(Fe,Ni)O(OH)] and garnierite (a hydrous nickel silicate). Magmatic nickel sulfide deposits form when magmas derived from the Earth’s mantle ascend into the crust, in some cases reaching the Earth’s surface, and crystallise into iron-magnesium-nickel-rich mafic and ultramafic rocks containing concentrations of Ni-rich sulfide minerals. In some deposits the Ni is associated with concentrations of platinum-group elements (PGEs) and copper, which increase the value of the nickel ore deposits. For example, the Noril’sk Ni-Cu-PGE deposit in Russia is estimated to have a value of approximately $1 trillion, representing one of the most valuable deposits in the world. Most of Australia’s nickel sulfide resources occur in Western Australia within ultramafic lava flows of Archean age. Other countries with major resources of nickel sulfide deposits include South Africa, Canada and Russia.

Western Australia has the largest nickel resources with 96% of total Australian resources, contained within nickel sulfide and lateritic nickel deposits. Queensland is the second largest with 4.5% (lateritic nickel), followed by Tasmania with 0.2%. Currently, all nickel is accessible for mining.

Underground extraction uses a variety of standard mining methods, and may be combined with open-pit mining simultaneously at the same deposit in order to access both shallow and deep parts of the deposit.

The ancient Chinese used nickel alloys (calling them 'paktong'); however, it was 1751 before nickel was first isolated by a Swedish chemist, Alex Cronstedt.

The sampling of some curious green-stained iron-rich rocks from the shores of Lake Lefroy in the Eastern Goldfields of Western Australia in 1947 represents an important event in the evolution of the nickel industry of Australia. Follow-up exploration led to the discovery in 1966 of the first major nickel sulfide deposit in Australia, heralding the initiation of Australia's nickel mining industry, an industry which has defined five world-class deposits (> 1 Mt contained nickel).

A best-selling customer and tech team favorite, these American-made end mills deliver high performance paired with the quality and durability the words 'Made In The USA' are synonymous with. Featuring a 10% premium micrograin carbide, a versatile 37° helix and a ZrN coating for increased lubricity, these end mills are ideal for machining aluminum and other non-ferrous materials. Available in a wide range of sizes and equipped with a unique geometry designed to prevent 'gumming' of the aluminum to the carbide (reducing chatter and preventing most failures), these end mills provide the power and versatility your aluminum milling applications demand.

In the 19th century, nickel was popular for making items such as cutlery. In 1889, James Riley gave an historic speech to the Iron and Steel Institute of Great Britain, declaring that tests had shown that a steel containing nickel gave the alloy almost unbelievable strength. From then on, nickel alloy steels became vital materials for a whole range of uses.

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 to 70% Ni. The final stage of processing is refining, involving pyrometallurical (heating) and hydrometallurgical (chemical) processes, which are utilised differently for nickel sulfide and lateritic nickel ores.
