Calamine (mineral) enough was known of metallic zinc to make brass solder directly by combining copper and spelter (zinc ingots). In 1738 a patent was granted to William Champion, a Bristol brass founder, for the large-scale reduction of calamine to produce spelter. In 1684 a paper presented to the Royal Society touched on the medicinal and veterinary properties of the compound when in finely powdered form. Calamine (mineral) Calamine is a historic name for an ore of zinc. The name "calamine" was derived from "lapis calaminaris", a Latin corruption of Greek "cadmia (καδμία)", the old name for zinc ores in general. The
Thermo Electric Ore Reduction Corporation Mill the Hodgkinson River scattered over the surface as bunches in quartzose boulders or in drifts interspersed with coarse gravels. In 1900, 91 pounds of molybdenite was also discovered. This was said to contain some of the finest specimens of molybdenite discovered anywhere in Australia. Wolfram is composed of a heavy gray-white metallic element, with pure wolfram being used mainly in electrical applications and is also the ore from which tungsten is refined. In 1899 wolfram was returning £38 per ton. Other than along the Hodgkinson, wolfram has been located in north Queensland at Bamford Hill approximately west-south-west of Cairns in
