PENTLANDITE
The ore from which
we get Nickel. Things as small as the coins in our pockets, and as large
as the trans-continental train, we find things made with Nickel. Due to
its strength and resistance to corrosion the steel industry uses
nickel to make stainless steel. The corrosive effects of salt on our roads
encouraged the use of stainless steel on the bodies of buses. Surgical
instruments, pots and pans, knives and forks are stainless. The Royal
Canadian Mint makes coins for dozens of Countries around the world.
Nickel and another mineral,
Cadmium are combined to make nickel cadmium batteries.
The hardness of Pentlandite
is 3.5 - 4 and the S.G. is 4.5 - 5.0. The mineral Pentlandite may contain
over 3000 different minerals.
