Nickel is commonly present in two principal ore types—sulfide or laterite. Sulfide ores are typically derived from volcanic or hydrothermal processes and usually include copper (Cu) and/or cobalt (Co), and often precious metals such as gold (Au) or platinum (Pt), palladium (Pd) and rhodium (Rh) (the platinum group metals or PGMs) (Naldrett, 2002, Hoatson et al., 2006).
Nickel allergy is a condition in which contact with items containing nickel causes an itchy rash and possibly blisters at the site of contact. The top photo shows a positive patch test (on the left), after a patch containing nickel was left on the skin for 48 hours.

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.

The Amazon is considered to have great potential for mineral assets, namely copper, tin, nickel, bauxite, manganese, iron ore and gold. As a result, governments are providing tax incentives for large-scale projects, in order to boost development. As extractive technologies improve, it is likely that the scale of Amazon mining will increase.
Nickel is a silvery-white metallic element found in the earth's crust. It can be combined with other elements to form nickel compounds. Because of its unique properties, nickel has many industrial uses. Most nickel is used in metal alloys because it imparts useful properties, such as corrosion resistance, heat resistance, hardness, and strength.
