Acid curing and agglomeration for heap leaching

The acid consumption in column leaching decreased from 2.7 to − 0.5 kg/t. A negative acid consumption in leaching means that the acid concentration in the leachate (overflow) was larger than that in the initial feed solution. The acid added in agglomeration was likely not completely consumed in acid curing.
