ABSTRACT:
A flotation concentrate in the form of a water suspension is treated with a reagent that nullifies the effect of previously used collectors. The suspension is filtered, and subjected to a mechanochemical treatment that includes chemical conditioning of the mineral surfaces and producing fresh surfaces by grinding with grinding bodies which additionally provide ions that promote selectivity. Grinding efficiency is controlled by the amount of material fed to the mill. The quantity of pulp flowing to the filter is determined and the supply of collector reagent to the filter and the rotary speed of the mill are regulated in response to the flow values.
