8 MacArthur, John Stewart
[br]b. December 1856 Hutchesontown, Glasgow, Scotlandd. 16 March 1920 Pollokshields, Glasgow, Scotland[br]Scottish industrial chemist who introduced the "cyanide process" for the commercial extraction of gold from its ores.[br]MacArthur served his apprenticeship in the laboratory of Tennant's Tharsis Sulphur and Copper Company in Glasgow. In 1886 he was appointed Technical Manager of the Tennant-run Cassel Gold Extracting Company. By 1888 he was advocating a treatment scheme in which gold was dissolved from crushed rock by a dilute solution of alkali cyanide and then precipitated onto finely divided zinc. During the next few years, with several assistants, he was extremely active in promoting the new gold-extraction technique in various parts of the world. In 1894 significant sums in royalty payments were received, but by 1897 the patents had been successfully contested; henceforth the Cassel Company concentrated on the production and marketing of the essential sodium cyanide reagent.MacArthur was Managing Director of the Cassel Company from 1892 to 1897; he resigned as a director in December 1905. In 1907 he created the Antimony Recovery Syndicate, and in 1911 he set up a small plant at Runcorn, Cheshire, to produce radium salts. In 1915 this radium-extraction activity was transferred to Balloch, south of Loch Lomond, where it was used until some years after his death.[br]Principal Honours and DistinctionsInstitution of Mining and Metallurgy Gold Medal 1902.Bibliography10 August 1888, jointly with R.W.Forrest and W.Forrest, British patent no. 14,174. 13 July 1889, jointly with R.W.Forrest and W.
