miller process of refining gold from ore

  • wohlwill process

    the resulting gold is 99.999% pure, and of higher purity than gold produced by the other common refining method, the miller process, which produces gold of 99.95% purity. for industrial gold production the wohlwill process is necessary for highest purity gold applications. when lower purity gold is required refiners often utilize the miller .

  • refining

    the term is broad, and may include more drastic transformations, such as the reduction of ore to metal for which see refining metallurgy . the refining of liquids is often accomplished by distillation or fractionation; this process is useful, for example, for isolating different fractions of petroleum.

  • miller process

    the miller process is an industrial-scale chemical procedure used to refine gold to a high degree of purity 99.95% . it was invented by francis bowyer miller patented 1867 . this chemical process involves blowing a stream of pure chlorine gas over and through a crucible filled with molten, but impure, gold.

  • gold parting

    in the modern period chlorination using the miller process, and electrolysis using the wohlwill process are the most widely used methods of refining gold by removing silver and platinum. these latest processes have been employed for over 100 years.

  • isakidd refining technology

    the current efficiency of the refining process depends, in part, on how close the anodes and cathodes can be placed in the electrolytic cell. this, in turn, depends on the strhtness of both the anode and the cathode. bumps and bends in either can lead to short-circuiting or otherwise affect the current distribution and also the quality of .
