H. Livingstone Sulman, a British chemist or metallurgist, published his first paper, "The examination of commercial glycerine", in The Analyst in 1886, with Edward E. Barry as second author. His next paper, "Improvements in gold extraction", appeared in the Transactions of the Institution of Mining and Metallurgy (Britain) in 1895 and was also issued as a pamphlet (London, 1895, 32p). It dealt with the recently introduced McArthur-Forrest cyanide process. That same year Sulman came to South Africa and as a visitor delivered "Notes on the behaviour of the haloid elements in conjuction with the cyanide process" at the May meeting of the Chemical and Metallurgical Society of South Africa in Johannesburg. His paper was published in the society's Proceedings (Vol. 1, pp. 109-122). However, before the paper was even delivered the president of the society, William Bettel*, criticised it in the South African Mining Journal. Unfortunately Bettel could not attend the meeting at which Sulman read his paper, having broken his leg in an accident. Sulman said that he could not understand the reason for Bettel's premature and hostile criticism and the chairman of the meeting called the president's conduct "most unprofessional".
In 1897 Sulman and Frank L. Teed described "The Sulman-Teed (bromo-cyanide) process of gold extraction" in the Journal of the Society for Chemical Industry. At that time he had settled in the Cape Colony. In 1905, with Hugh Kirkpatrick Piccard and John Ballot*, he was working on an improved method of concentrating ores. The next year he and Piccard applied for a patent relating to this process. Sulman and Picard later wrote a book on The theory of concentration processes involving surface tension (1920), dealing with the process of flotation and the phenomenon of capillarity.
