CIL Gold Loss Characterization within Oxidized Leach Tails

This procedure is more appropriate for oxidized leach tails because it takes account of the mineralogy of the ore during the procedural development of diagnostic leach tests. The findings are useful to understand the source of the problem gold losses, and at the same time to optimize the operation for better gold recovery.
