Clement Dixon, consulting mining and metallurgical engineer, was the son of John James Dixon and his wife Hannah Elizabeth Dixon. He studied at the New Zealand Government School of Mines at Waihi, and qualified as superintendent of milling, cyaniding and assay plants. He subsequently served on the School's council, while working as a mining engineer and as representative of the Johannesburg-New Zealand Venture Syndicate, before coming to South Africa in 1893. In the Transvaal he was awarded a diploma as mine manager after passing the necessary government examinations. He worked as manager of mines and metallurgical works and as consulting engineer on the Witwatersrand, and served with the British forces during the Anglo-Boer War (1899-1902). In 1905 he was general manager of the West Bonanza Gold Mining Company at Klerksdorp. That same year he renewed his licences for 50 claims on the farm Kaffirskraal No. 198.
Dixon was initially as associate and later a member of the (British) Institution of Mining and Metallurgy. In 1898 he became an associate of the Chemical and Metallurgical Society of South Africa. After the war, in 1902, he was elected a member of the renamed Chemical, Metallurgical and Mining Society of South Africa and subsequently served briefly on its council. In June 1902 he delivered the first post-war paper to members of the society, "Notes on the treatment of slimes by filter presses", which was published in its Journal (Vol. 3(2), pp. 13-15).
Moving to Rhodesia (now Zimbabwe) some time before 1908, Dixon worked in Bulawayo for five years as mining engineer and as representative for Messrs Farrar Bros of Johannesburg and London, and the Anglo-French Matabeleland Co. Thereafter he set up in private practice as a consulting engineer to various companies and syndicates. He became a member of the North of England Institute of Mining and Mechanical Engineers, was elected a Fellow of the Royal Colonial Institute, served on the executive council of the Rhodesian Chamber of Mines, was a town councillor of Bulawayo, served as president of the Rhodesian Association for the Destruction of Flies and Mosquitoes, and made professional visits to Australia and New Zealand. He joined the Rhodesia Scientific Association, and served as its president for 1916/7. By 1914 he was still a member of the Chemical, Metallurgical and Mining Society of South Africa, and a corresponding member of its council.
Dixon was married to Mary Emmeline Hume, with whom he had a son. He died of pneumonia on the island Cyprus in 1924.
