THE ALLOY THAT TIME FORGOT
Early on, ore was separated into "a mixed copper-nickel ore, copper pyrites, pyrrhotite and diorite rock," with nickel content 1.28-8.12% and copper 0.49%-15.71% between 1892-991. It was at Creighton, mined from 1901, that pyrrhotite with a 2.3:1 nickel copper ratio was discovered and became synonymous with Monel's natural composition.
