dc.description.abstractJet reactor technology was applied to the leaching of gold from refractory ores. By bringing gold-bearing ores into contact with cyanide, using a high-pressure jet reactor prior to agitation, bold recovery is increased and leach time dramatically reduced. The increase in dissolution kinetics can be ascribed to the high-pressure jet stream, coupled with microcracking of the particles due to the high velocity collisions within the reactor chamber. Initial tests using a free milling ore with a head-grade of 5 g Au/ton and particle size of 80% passing 75 μm demonstrated 99% recovery after only 2.5 hours of contact time.
