The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold Here is practical, timely information on Placer Mining Methods and equipment used in placer gold recovery Included is detailed information on equipment, practices, recovery factors, efficiency, design, and, where available, costs Selected gold recovery operations are described in detail In addition, the reported efficiency and reliability of various types of equipment used today is Placer Mining Methods Mineral Processing Most gold mined in Australia today cannot be seen in the rock, it is very fine grained and mostly has a concentration of less than 5 grams in every tonne of rock mined The feasibility of mining low concentrations of gold largely depends on the price of gold Gold is bought and sold every day on international gold marketsGold Geoscience Australia
