It has revolutionized a 110-year old metal refining process known as the "Mond Process" or the "
carbonyl process" when applied to nickel and iron, and generically known as the "vapour metallurgy process," when applied to other elements.
Some years after this footage was shot the family moved to Clydach, Mr Priddey having obtained a job at 'the Mond' - a nickel carbonyl refinery opened in 1902 and built by Ludwig Mond, inventor of the nickel
carbonyl process. By 1910, half the village was employed at this refinery.
Very pure nickel (>99.99%) is produced by Inco Ltd using the well-established
carbonyl process which depends on the formation and decomposition of nickel carbonyl gas (Boldt, 1967).
