Diagnostic leach test procedure
WebNov 24, 2011 · Diagnostic leaching is essentially about selecting the chemical reaction and conditions that will dissolve a specific mineral so its presence in ore can be quantified and its likely processing behaviour estimated. It is a process that requires applying knowledge of the mineral’s chemistry and trying different reagents, often with an eye to ... WebThis 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.
