This episode of Mining Now takes us to Perth, Australia, where we continue our interview with Mineral Process Control Business Manager Nathan Edwards. In this part 2 episode, he explains how gold cyanidation works and how their products, such as Leachwell and Assay Tabs, help in this process.
LeachWELL 60X is a reagent-grade catalyst formulated for fast cyanide leach gold assaying. When used with 5% cyanide the dissolution rate of gold, copper, and silver is increased more than sixtyfold. The leach rate for gold under appropriate conditions, for example, is approximately 1 µm per minute!
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.
Assay Tabs have been formulated for fast cyanide leach gold assaying. Each Assay Tab weighs approximately 10 g and contains the appropriate amount of reagents (~75 % NaCN and ~25 % LeachWELL) to facilitate a 1-hour leach when used according to our instructions. The leach rate for gold for example is approximately 1 micron per minute!
Three-tier Bottle Roll Machine
MPC has also produced two versions of a three-tier bottle roll machine. One version was constructed to be flat-packed for shipment by air. The machines consisted of 15 x 3m long rollers in three layers of 5. The rollers were Linatex coated and each roller was driven by a long-life O-ring sealed chain. The machine has a capacity of around 250 x 4.5L jars. The air freight version capacity is slightly less. It can also accommodate 2L as well as 1L jars.
