Nickel (element #28, symbol Ni) is a silvery shiny, metallic element. It can be hammered into thin sheets, which means it is malleable. Nickel was discovered in 1751 by Axel Fredrik Cronstedt. Iron, cobalt and nickel (numbers 26, 27 and 28 on the Periodic Table) are the only three elements known to be ferromagnetic (the strongest type of ...

Calcination is the process of heating a solid material in order to cause chemical separation of its components. The diversity of chemical separation lends calcination to accomplishing a range of objectives, from the removal of chemically bound (crystalline) water, to the volatilization of contaminants from a source material, thermal decomposition, and even …

The fraction of nickel in pentlandite (nickel ore) is only 5.5 × 10 −3 g Ni/g ore. To supply 1 g of pure nickel to an industrial process requires that at least 181 g of pentlandite be dug. If the nickel mine is underground, the upper layers of topsoil and clay are also excavated, perhaps a forest is also cut and biotic material degraded.
