Suppressing Heavy Metal Leaching through Ball Milling of Fly Ash

Jul 8, 2016 . Abstract: Ball milling is investigated as a method of reducing the leaching concentration (often termed stablilization) of heavy metals in municipal solid waste incineration (MSWI) fly ash. Three heavy metals (Cu, Cr, Pb) loose much of their solubility in leachate by treating fly ash in a planetary ball mill, in.

Ammonia Release Characteristics from Coal Combustion Fly Ash

showed that the residual ammonia on the treated ash was less than 1 ppm based on the ash mass. The ammonia-free ash was then mixed with ground NH4HSO4 or (NH4)2SO4 in a ball mill for 15 hours at a determined mass ratio of the ash and the salts. The purity of ammonium salts was 98%, and the salt crystals were.
