The Rosebery concentrator operates on a 12hour, seven day, continuous shift roster. Throughput varies from 75 to 85 tonnes per hour. The milling circuit is preceded by two parallel roll crushers in closed circuit with five millimeter single deck vibrating screens. The ore then passes into a twostage grinding circuit, consisting
· For closedcircuit appliions, it is generally better to use higher feed rates ( up to 80–100 t/h for a Knelson Concentrator XT30) to maximize gold production rather than unit recovery. Opencircuit appliions, such as recovery from flashflotation concentrates or scavenging goldroom tailings, would use much lower feed rates.
gravity separation: fl knelson concentrator " The combination of the RG100 with the Knelson MD12 concentrator is an excellent match. Even the most stubborn clays are disintegrated by the autogenous scrubbing action in the drum section (assuming correct feed rate), and this plant combo is excellent for processing of eluvial and alluvial ...
