A METHOD FOR AUTOMATIC COLLECTOR CHEMICAL CONCENTRATION CONTROL IN A FROTH FLOTATION PROCESS

摘要

The invention relates to a method for automatic control of at least one collector chemical or flotation chemicals in a froth flotation process in a froth flotation system. In the method there is determined a rate of introduction of ore tonnages into the flotation system. An initial flow rate of a collector chemical or other flotation chemicals is provided to the flotation system based on ore feed rate (t/h) or metal content in the feed (wt%). Slurry samples are extracted from tailings from at least one flotation cell in the series and/or flotation feed with recycled process water. The slurry samples are filtered and a resulting liquid sample is analyzed to determine a concentration of the collector chemical. The residual concentration is utilized for to determining an updated flow rate of the collector chemical or other flotation chemicals to the flotation system.
