John Stewart MacArthur

John Stewart MacArthur was a chemist from Glasgow.[1] He is credited with the development of the MacArthur-Forrest cyanidation process in 1887, used to extract gold in South Africa. His patent for the process was voided. The long lasting legal issues about the cyanidation patents Macarthur turned to other businesses. He was interested in vanadium extraction from ore containing significant amounts of radium. From this enterprise he turned to the production of radium. He first started the Radium Works in Halton in 1911.In 1915 he moved it Balloch, West Dunbartonshire to and renamed it to Loch Lomond Radium Works.[2][3] MacArthur died 16 March 1920.[4]
