Ball mill operation in cip circuit

Apr 20, 2021

The Higginsville Mill flowsheet (shown below) is a conventional CIP gold circuit with quaternary crushing and ball milling with a gravity recovery circuit on the cyclone underflow. Grinding is followed by leaching with a production capacity of 1.4Mtpa. The gravity recoverable gold from the mineralization, which is recovered through a Knelson
