Typical applications are leaching of gold ores with cyanide, chemical and wastewater treatment processes where large amounts of gases are required to be dissolved in fluids. The reactor is especially efficient for high rate oxidation of sulphides, since the slurry (solution stream) is accelerated at the gas addition point and this increases shear rates in the subsequent flow mixing zone.

· At current gold prices this is worth about US$600. Both smelter treatment charges and oxidation or bio-leach costs are at least $200/t of concentrate and payables/recovery in the 90% range, so a minimum GSR for effective downstream processing is around 0.5. Clearly this is a function of gold price, but in the current gold price and cost ...
