  • The role of silies in gold processing

    The results from several previous chapters are drawn together and examined again in a silie rich gold ore. The results of a leaching test in an acidic chloride system on an oxide gold ore and ground products in different systems verified both the effect of different grinding methods on leaching of gold and extent of pregrobbing in good agreement with the results on pure silies. Finally ...

  • Sudan

    In 1988, about 78,000 metric kilograms of gold ore were mined in Sudan. In late 1990, Sudan and two French mining companies formed a joint venture company to exploit gold reserves in the Khawr Ariab wadi in the Red Sea Hills. Chrome ore was mined in the Ingessana Hills in Al Awsat. In the late 1970s, output was reportedly more than 20,000 tons a year, of which more than four .
