LeachWELL GC is a technical grade catalyst that has been formulated for intensive cyanidation of Knelson and other gold concentrates. Recoveries above 99.9% within a few hours are common when using LeachWELL GC. Residues can therefore be safely discarded. Advantages. Intensive cyanidation of concentrates offers far greater security.

Following the 3% annual growth scenario Back to Normal, aviation will have contributed 0.09 ± 0.04 °C to global warming by 2050 (figure 2 ). More than half of that warming will be caused in the next three decades, contributing a 6%–17% share to the remaining 0.3 °C–0.8 °C to stay within a 1.5 °C–2 °C target.

An Acacia intensive leach reactor is used to dissolve gold contained in the concentrate, and this gold is then recovered from solution by electro winning. The concentrate is currently being tabled using a Gemini table.
