The type of limestone treatment system used depends on the amount and ionic state of the iron in the AMD. Three groups of AMD are considered here (1) low iron AMD, (2) ferric iron AMD, and (3) ferrous iron AMD. Low Iron AMD. Low iron AMD is the easiest to treat. Limestone beds (Figure 8) and pulverized limestone (Figure 9) can be effectively used.
