Claude Vautin

Claude Theodore James Vautin (1855—1939) was a metallurgist and chemist. He developed, jointly with James Cosmo Newbery, the Newbery-Vautin chlorination process of extracting gold from pyrite ores, and held numerous other patents. Sometimes described as British, he was Australian-born and spent the first part of his career in Australia, and some years in South Africa, but subsequently lived in England. His career was marred by his conviction, in April 1899, of intent to defraud and obtaining money by false pretences.
