May 15, 2017259080121794905The data obtained indicated that most of the silver present in fresh CLC tailings could be extracted using a hot acidic saline solution (Romero et al., 2003) and that the same amount was extractable from tailings that had been bioleached at 30 C. Much less silver was extracted from CLC tailings that had been bioleached at 45 C, which may have been due to more being

Sep 11, 2014The gold and silver tailings were generated from conventional mining operations between 1992 and 1999. The original mining operations recoveries were poor (< 30%) and considerable amounts of ore were placed in the dam. The dam has an estimated 5,137 million metric tonnes of ore, grading 3.8 g/t gold and 38.6 g/t silver.
