Banro corporation recently announced in its press release that it will be adopting Maelgwyn Mineral Services proprietary Leachox™ process to enhance the recoveries in its 43-101 compliant Feasibility Study. According to the press release the flow sheet comprises the following main steps:

  • Production of sulphide concentrates by flotation (conventional process)
  • Fine-grinding the flotation concentrate
  • Contacting the fine milled product with oxygen in Aachen reactors™ (proprietary equipment) to effect the partial oxidation of sulphides, which will in turn liberate the refractory gold making it amenable to conventional cyanidation.
