Abstract

As part of a systematic programme for correlating mineral engineering process variables1,2, flotation machines are now being investigated. There is no need to stress the engineering importance of the flotation process. First applied more than fifty years ago for the recovery of fine sulphide minerals from Australian gravity plant tailings, to-day it is the only method for treating the major base metal sulphide ores, and is becoming of increasing importance for non-metallic ores and coal. As a mineral engineering operation, it is often second only to fine grinding in power consumption. Despite this, empiricism largely prevails from choice of equipment to control of process variables.
