The typical HIGmill flow sheet for regrind circuits is simple and straightforward. Regrind feed from flotation goes to a scalping cyclone. The cyclone overflow bypasses the HIGmill and the cyclone underflow is pumped into the mill, where the target product size is produced in a single pass. As there are no recirculating loads, the pumps,
