Through testing, gravity separation, and leaching using the Clean Mining / CSIRO non-toxic process, Radio Gold Mine in Southern Cross Australia has achieved 95% gold extraction with the bulk of recovery occurring within the first 4 to 5 hours.
Following successful leach testing results of other global mining clients with 80% – 90% leaching recovery, Clean Mining, part of the Clean Earth Technologies Group, is building momentum in its efforts to being the genuine non-toxic alternative to cyanide and mercury in gold processing.
The Radio Gold Mine ore (quartz vein hosting gold in granite) drew 67% of the gold with gravity, and 95% gold recovery was achieved with the use of the non-toxic Clean Mining tank leaching process.
Additionally, the bulk of gold recovery peaked at 4 hours, indicating fast leaching kinetics along with low reagent consumption. Using Clean Mining’s non-toxic processes, Radio Gold Mine is now progressing to the design phase of their processing plant in Southern Cross for 2021.
