· In the early morning of 22 January 2007 the survey team on the site of a fluorspar mining operation in northern Derbyshire was disturbed by the noise of plastic barrels being propelled across the mine site and on to the public road. Within halfanhour the residents of the nearby village of Stoney Middleton found their doorsteps awash with a mixture of tailings and rainwater. The flood ...
Fluorspar is a mineral cargo which is mined and then is subjected to a washing process. The mineral consists of finely divided particles and is occasionally shipped at a too high moisture content, of the order of 9 to 10 per cent. In such a form the mineral is liable to liquefy during ocean transport and this liquefaction may result in shift of cargo. Under extreme circumstances this shift of ...

· Fluorspar (the commercial name for fluorite or CaF2) may just be the most important but leastknown industrial mineral. Among other appliions, it's most commonly used in manufacturing aluminum, steel, concrete and toothpaste. It's also the precursor ingredient for hydrofluoric acid, which is vital to the manufacture of all fluorocarbons, which are used in refrigerators, air conditioners and ...
Flotation of Fluorspar. The thickened tailing from the barite section is subjected to twostage conditioning in order to effect depression of the gangue in the first conditioner using depressant 60.

sampling. It is the most accurate method of sampling a tailing deposit, but it is usually too expensive to use. This method is used chiefly to confirm the results of auger sampling. Auger drills used for sampling tailing deposits are similar to wood augers. They obtain a sample by boring a vertical hole to the desired depth and on being withdrawn
