Zinc precipitation from eluates should not require deaeration as oxygen should be removed from the eluate as part of the cyanide degradation reaction, which will occur at elevated temperature in contact with

  • Technology of recovery of associated gold from

    Possible sources of gold are hydrothermally altered ores, some part of rock spoil banks, and rejects of iron ore treatment. In dry and, in particular, wet magnetic separation of ores magnetic concentrates partially freed from sulfides and gold accumulates in the rejects.Sensor-Based Ore Sorting Technology in ,As a high Gold recovery is a condition for the economic feasibility of a sensor-based ore sorting installation, it becomes clear why previous COLOR-based gold ore sorting attempts have often failed . The development has led to two pilot installations: one at Björkdals Mine in Sweden [ 81 ], and the other one, in combination with an XRT-baser sorter, at Corrego do Sitio Mine in Brasil [ 82 ].
