The following flotation reagent mixing system is typical for the flotation reagent mixing systems: A-208, Xanthate and Sodium Silicate.
The reagent mix tanks, for the above mentioned reagents, are located on the basement floor. Feed chutes from the main operating floor carry dry or wet reagents to each mix tank. Either reclaim or fresh water is added to the mix tank with the reagent, the reagent is mixed with an agitator, and then it is pumped up to its respective day tank on the upper operating floor for distribution. Parallel metering pumps regulate the flow of the reagent from the holding tank to the various feed points. One pump is run while one pump is generally held on stand by. An overflow line from the day tank allows flow back into the mixing tank. Pressure gauges are mounted near the bottom of each mixing tank, and have been calibrated to indicate level in the tanks. Pressure gauges have been installed at the transfer pump discharge lines. The holding tanks have level gauge glasses and high level float switches, the latter alarming the mill control panel annunciator. The 110 volt starters for ….Read more
