Flotation reagent dosing

Flotation is one of the most common processes for mineral recovery and one of the most important, in which minerals float attached to bubbles thanks to the dosing of chemical reagents suitable for each mineral.

For mineral recovery to be efficient, a precise system is required that includes metering pumps and suitable accessories to achieve the recovery that metallurgy requires; The more complex the metallurgy and the operating conditions, the more specific the design of the dosing system must be: from a dosing pump with accessories for local control to an automatic reagent preparation skid with self-calibrating dosing.
