As mineralogy has become more complex in the long history of gold processing, the process routes and equipment used had to adapt to the changing conditions. Starting with atmospheric leaching, complex sulphide mineralogy has led to the development of pressure oxidation autoclaves (POX) as well as bioleaching process routes. Agitation systems have picked up the challenge of serving all of the existing process requirements for CIL, CIP, POX and bioleaching applications. Be it high temperatures or high pressures and demanding chemical-physical requirements to the material of construction, agitation systems always have to cope with the same challenges: achieving the required mass transfer, providing proper gas dispersion, blending the diverse feed stream and of course achieving highest availability and reliability. This presentation and technical paper will provide the latest state-of-the-art technologies and improvements of agitation systems that render possible the next step towards a new generation of gold processing plants.
