Lateritic nickel ore deposits - Wikipedia
Lateritic nickel ores formed by intensive tropical weathering of olivine-rich ultramafic rocks such as dunite, peridotite and komatiite and their serpentinized derivatives, serpentinite which consist largely of the magnesium silicate serpentine and contains approx. 0.3% nickel.
Properties and applications of electroless nickel
The magnetic properties of electroless nickel are of ex-treme importance as they have been responsible for one of the single largest applications for high phosphorus deposits, i.e. as an underlayer for magnetic coatings in the production of memory discs. The magnetic response of electroless nickel varies greatly with phosphorus content, as shown in Figure 5.4 The ferromagnetism associated with ...
