    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. The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis.

This part treats the strategy of beneficiation as a combination of several processes. Joining together these units make possible to develop an appropriate flowsheet whose objective is to recover gold and the precious metals present in the ore. Perhaps, one of the greatest challenges in the gold mi
  • Gold Processing Methods & Gold Ore Extraction

    Of all the methods of extracting gold & processing it from its ore, I used a few to evaluate two principal flowsheets in this case study. The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration. Tests that mirror each of these unit operations were utilized to evaluate the principal flowsheets. This page offers a comparative review of gold recovery
