Abstract

A method of monitoring the operation of a froth flotation process having an input stream consisting of raw feed, a first output stream consisting of frothed product to be reclaimed and a second output stream consisting of tailings to be discarded, comprises determining the solids content of at least the input and the tailings stream and varying the process conditions, such as the amount of flotation reagent added in response to the readings attained. The readings are preferably effected by turbidity measurement of samples withdrawn from the streams which are diluted in proportion to reduce their solids content prior to turbidity measurement. <IMAGE>
