John Collett Moulden died on December 19th, 1937, at the age of 64.
He was born in Australia and received his early training at the Adelaide School of Mines. In 1891 he came to London for a three-year course at the Royal School of Mines, and obtained his Associateship in mining in 1894. In the following year he was granted an Associateship in metallurgy, accompanied with the award of the ‘Bessemer’ medal for that year. He then returned to Australia and began a private practice at Kalgoorlie.
In 1896 he was appointed chief chemist to the Broken Hill Block 14; he was promoted to assistant general manager after a few months and in 1899 he became manager of the Broken Hill Junction Silver and Lead Mining Co. Two years later he went to Cockle Creek, near Newcastle, N.S.W., as assistant manager and chief metallurgist in the Sulphide Corporation’s works, and in 1906 he was made acting-manager. The Corporation then transferred him to Broken Hill as acting-manager of their Central mine. In the same year, however, he came again to England as general manager of the Central Zinc Co., Ltd., at Seaton Carew, Durham. Later he was appointed general manager of the Sulphide Corporation in London, and he maintained that association until his death. He was a director of several companies.
Mr. Moulden was elected a Member of the Institution in 1910, and was a Member of Council from 1917 to 1929, serving as Vice-President from 1921-23.
