New techniques in the characterisation of complex gold ores

Ores from the Pilbara region of Western Australia are examined as examples of complex gold ores with varying mineralogy and metallurgical behaviour. Three main ores have been investigated, including the Kitchener ore, as an example of an atypical complex quartz carbonate ore, the North Shaw ore, as an example of a typical complex refractory

Aug 07, 20130183;32;With some borax, heat, and a little know how, its possible to extract pure gold from a sample of ore. This is because using borax as the flux reduces the melting point of all the elements in a piece of ore, including gold. While out in the field, a gold prospector can grind and wash a piece of ore, then mix it with borax in a plastic bag.
