Claim:
A method, comprising: (a) receiving, at a site of end use and from a manufacturer at a remote location, a free-flowing, particulate sorbent, the particulate sorbent particles having a first size distribution when received on site; (b) introducing the particulate sorbent into a chamber of an agitated media attrition mill, the agitated media attrition mill being located on site; (c) while in the chamber, reducing the sizes of the introduced particulate sorbent by inter-particle collisions to produce milled sorbent particles having a second size distribution, wherein the second size distribution is smaller than the first size distribution, and wherein a desired particle size of the milled sorbent particles is a size of less than about 15 microns; and (d) thereafter introducing, on site, the milled sorbent particles into a contaminated flue gas stream to remove one or more contaminants.
