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 which collisions between balls and fly ash drive various physical processes, as well as

[[abstract]]Water-extracted municipal solid waste incinerator (MSWI) fly ash was treated by a process of wet ball milling, using desalinated water as the milling solution. We investigated the influence of the milling process on the partitioning and leaching characteristics of lead (Pb) and the particle size distribution.

This paper reports the synthesis of a solid-form geopolymer by ball-milling of raw materials of varying compositions together in the solid state. This resulted in the formation of ready-to-use geopolymeric precursors, which on ‘just the addition of water’ led to the development of solid-form geopolymeric binder with enhanced reactivity and properties.
