For a correct concentration of the desired metal, it is necessary to maintain alkalinity in the solution containing the mineral and to correct the acidic pH of the waters derived from said mineralogical processes.
CALCIUM OXIDE
It acts in the flotation processes, controlling the pH of the system and as a precipitant. It is used mixed together with other agents such as: foaming, activators, precipitators.
CALCIUM HYDROXIDE
In this case, it acts as a regulator of the pH of the water generated in the process prior to its discharge into the river bed, allowing in turn the separation of the metals contained in those waters for reuse.
