As we know, the gold extraction process takes advantage of the tremendous physical affinity that activated carbon has for gold. However the degree of ‘activity’ is often overlooked or untested on site. Carbon activity can range from 20-40% prior to regeneration and up to 70-90% post regeneration. A lot of variability tends to occur in activity levels. The calculator puts this into perspective. As little as a 5% increase in activity can have a significant impact on the bottom line. With HEAT Systems Rotary Kilns you can be assured that your activity levels are maximised following every regeneration.
