A. D. Carmichael
Archibald Drummond Carmichael (born 24 February 1859) was an industrial chemist who made important advances in processing mine tailings to recover valuable metals. History Carmichael was born in Lanarkshire, Scotland, and educated in Glasgow. He studied chemistry under Professor Dittmer at the Andersonian College ("The Place of Useful Learning"), and gained experience at city analysts Wallace, Tatlack, and Clarke. He worked at Charles Tennant's " St Rollox" laboratories adjacent the Monkland Canal for 14 years, rising to the level of chief technical chemist. In 1889 left for Victoria, Australia, where he found employment with Felton, Grimwade & Co and with the Australian Explosives and Chemical Company. He joined the Metals Extraction Company, and was sent to Broken Hill with metallurgist Askin Nicholas to troubleshoot one of Junction North mine's processes. In 1894 he joined Broken Hill's Block 10 Company as assayer, then in October 1896 joined "The Proprietary" (BHP). Ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lanarkshire
Lanarkshire, also called the County of Lanark ( gd, Siorrachd Lannraig; sco, Lanrikshire), is a historic county, lieutenancy area and registration county in the central Lowlands of Scotland. Lanarkshire is the most populous county in Scotland, as it contains most of Glasgow and the surrounding conurbation. In earlier times it had considerably greater boundaries, including neighbouring Renfrewshire until 1402. Lanarkshire is bounded to the north by the counties of Stirlingshire and Dunbartonshire (this boundary is split into two sections owing to Dunbartonshire's Cumbernauld exclave), to the northeast by West Lothian and Mid Lothian, to the east by Peeblesshire, to the south by Dumfriesshire, and to the west by Ayrshire and Renfrewshire. Administrative history Lanarkshire was historically divided between two administrative areas. In the mid-18th century it was divided again into three wards: the upper, middle and lower wards with their administrative centres at Lanark, Hamil ...

Zinc Corporation
Consolidated Zinc was an Australian mining company from 1905 to 1962. History The company's initial operations focused on extracting zinc from mine tailings of the Broken Hill Ore Deposit at Broken Hill, New South Wales, Australia. The company was founded in Melbourne on 9 September 1905 as the Zinc Corporation Limited, to exploit residual zinc concentrations with an estimated value of $12 million in the 6 million tons of mine tailings deposited from mining activities over the previous 20 years. Key figures involved in the effort included William Baillieu and William Sydney Robinson. Also involved was future U.S. president, but then a mining engineer working for Bewick, Moreing and Company, Herbert Hoover, who inspected the tailing dumps in the group's investigations prior to formation of the company. Other investors in the new company were Clark & Robinson (William Clark, Lionel Robinson and Company), and Arthur Terrell. They established concentrating mills at Broken Hill ...

Tailings
In mining, tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction (gangue) of an ore. Tailings are different to overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed. The extraction of minerals from ore can be done two ways: placer mining, which uses water and gravity to concentrate the valuable minerals, or hard rock mining, which pulverizes the rock containing the ore and then relies on chemical reactions to concentrate the sought-after material. In the latter, the extraction of minerals from ore requires comminution, i.e., grinding the ore into fine particles to facilitate extraction of the target element(s). Because of this comminution, tailings consist of a slurry of fine particles, ranging from the size of a grain of sand to a few micrometres. Mine tailings are usually produced from the mill in slurry form, which i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Register (Adelaide)
''The Register'', originally the ''South Australian Gazette and Colonial Register'', and later ''South Australian Register,'' was South Australia's first newspaper. It was first published in London in June 1836, moved to Adelaide in 1837, and folded into '' The Advertiser'' almost a century later in February 1931. The newspaper was the sole primary source for almost all information about the settlement and early history of South Australia. It documented shipping schedules, legal history and court records at a time when official records were not kept. According to the National Library of Australia, its pages contain "one hundred years of births, deaths, marriages, crime, building history, the establishment of towns and businesses, political and social comment". All issues are freely available online, via Trove. History ''The Register'' was conceived by Robert Thomas, a law stationer, who had purchased for his family of land in the proposed South Australian province after be ...

Leslie Bradford
Leslie Bradford (9 March 1878 – 20 June 1943) was a mining engineer in Australia credited with several important inventions in the treatment of metal-bearing ores. History Bradford was born in India, a son of George A. Bradford, Minister of Salt in the Indian Government, and was educated at Bishop Cotton's school. In 1892 he moved with his parents to Adelaide, South Australia, where he studied for four years at the School of Mines, and was their youngest student to gain diplomas for mining, metallurgy, and chemistry. In 1897 he gained employment with the Block 14 Company of Broken Hill as assistant assayer, and the following year was put in charge of that section. In 1898 he joined BHP at their treatment works in Port Pirie, and in 1899 was appointed their chief assayer and metallurgist. While at Port Pirie he developed a process of separating sulphide ores by froth flotation, earlier investigated by G. D. Delprat and Charles Vincent Potter. Bradford's breakthrough was the us ...

The Barrier Miner
''The Barrier Miner'' was a daily broadsheet newspaper published in Broken Hill in far western New South Wales from 1888 to 1974. History First published on 28 February 1888, ''The Barrier Miner'' was published continuously until 25 November 1974. Copies are available on microfilm and online via Trove Digitised Newspapers. The paper was revived briefly in 2005; an index to births deaths and marriages has been prepared which also notes additional publication dates between 16 December 2005 and 31 July 2008. The paper closed down for a second time in 2008 with the managing director, Margaret McBride stating that "...due to commercial reasons the paper would no longer service Broken Hill and the region...". ''The Barrier Miner'' served the growing mining community of Broken Hill, when the area was found to have lead ore and traces of silver. It was not until late 1884 or early 1885 that rich quantities of silver were found and the Broken Hill Proprietary Company (BHP) was floated ...

Refractory
In materials science, a refractory material or refractory is a material that is resistant to decomposition by heat, pressure, or chemical attack, and retains strength and form at high temperatures. Refractories are polycrystalline, polyphase, inorganic, non-metallic, porous, and heterogeneous. They are typically composed of oxides or carbides, nitrides etc. of the following materials: silicon, aluminium, magnesium, calcium, boron, chromium and zirconium. ASTM C71 defines refractories as "...non-metallic materials having those chemical and physical properties that make them applicable for structures, or as components of systems, that are exposed to environments above ." Refractory materials are used in furnaces, kilns, incinerators, and reactors. Refractories are also used to make crucibles and moulds for casting glass and metals and for surfacing flame deflector systems for rocket launch structures. Today, the iron- and steel-industry and metal casting sectors use appr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
