Arthur Yates, metallurgist, became a member of the Chemical and Metallurgical Society of South Africa in 1899 and remained a member after the Anglo-Boer War (1899-1902), when the society was renamed the Chemical, Metallurgical and Mining Society of South Africa. In the membership list for 1905 his address is given as Benkoelen (now Bengkulu), Sumatra, Indonesia. However, he seems to have returned to the Witwatersrand soon afterwards. As co-author with S.J. Truscott* he contributed a paper on "A proposed method of treating sand residue dumps" to the society's Journal (1905/6, Vol. 6), followed by "Notes on the use of the filter press for clarifying solutions" (with Truscott as co-author; 1906/7, Vol. 7, pp. 3-5). Subsequent papers by him dealt with "Grading assays and grinding efficiencies" (Journal, 1908/9, Vol. 9, pp. 187-) and "The smelting of gold precipitates and bullion with oil fuel" (Journal, 1908/9, Vol. 9, pp. 429-).
