When water is used in disciplines like manufacturing and ,mining,, this often changes, with the water being too ,acidic, or ,alkaline, to use again or dispose of safely. pH control systems create reusable water by returning those levels to normal; if the pH is five or below (i.e. too ,acidic,), alkalis like lime are added; if it’s six or above (too ,alkaline,), acids (like sulfuric acid) are put in.

The authors propose the use of acidic mine drainage to neutralize alkaline flotation leachate. The conducted experiments indicated that it is possible to reduce the pH from ~12 to values close to neutral by using a volume of acidic mine wastewater four times smaller than that of flotation wastewater.

“Mining wastewater often contains substantial magnesium and aluminium concentrations. This means that we can create hydrotalcites utilising common contaminants that are already present in the wastewater, by simply adjusting their concentrations and adding alkaline compounds to …
