Fly ash (FA) is the principal industrial waste byproduct from the burning of solid fuels. FA is a powdery solid that is constituted mostly of unburned carbon (UC), metal oxides (Si, Fe, Ca, and Al), and other inorganic substances. UC is an inexpensive source of activated carbon that plays an important role in FA adsorption capacity.

In that study, fly ash was milled with CaO in a dry planetary ball mill. It was found that Pb elution from fly ash could be inhibited by 93% by MC treatment as compared to untreated fly ash. This effect may have been the result of the high surface energy of the ground particles, which caused the formation of insoluble compounds.
