Table 6. Sulfur species in the 12 <strong>fly</strong> <strong>ash</strong>es (percent weight).Fly <strong>ash</strong> Sulfate S Sulfide S Total S<strong>ash</strong>es were also characterized by greater amounts <strong>of</strong> Na, Ba, <strong>and</strong> Sr, whileA1 <strong>and</strong> Fe were lower as compared with the amounts in the Illinois Basinsamples. These findings are similar to those reported in the <strong>coal</strong> <strong>and</strong> <strong>fly</strong><strong>ash</strong> literature, in which higher levels <strong>of</strong> Ba, Ca, Mg, Na, <strong>and</strong> Sr have beengeneral ly associated with western l ignite <strong>coal</strong> s ( Abernathy, 1969; Furr etal., 1977; Gluskoter et al., 1977; <strong>and</strong> Natusch et al., 1977).The specific gravities reported in Table 2 for the Illinois Basin <strong>fly</strong> <strong>ash</strong>esare close to the specific gravity <strong>of</strong> pure quartz (GO2), which is 2.65.The higher specific gravities <strong>of</strong> the two lignite <strong>fly</strong> <strong>ash</strong>es W2 (3.0) <strong>and</strong> W3(3.1) were probably due to the low carbon content (Table 4) <strong>and</strong> thedominant mineral s--periclase (MgO), with a density <strong>of</strong> 3.58 <strong>and</strong> anhydri te(C~SO~), at about 2.92.The trace constituent concentrations in the <strong>fly</strong> <strong>ash</strong>es (Table 6) wereextremely variable. Arsenic in the I1 linoi s Basin samples (11-19) rangedfrom 21 to 360 mg/kg; Co varied from 38 to 88 mg/kg. Zinc was the mostvariable, ranging from 90 to 2,100 mg/kg. In spite <strong>of</strong> the variable nature<strong>of</strong> <strong>fly</strong> <strong>ash</strong>, the Illinois Basin samples can be broadly characterized <strong>ash</strong>aving greater trace constituent concentrations than the three westernsamples have. These trace constituents are (in order <strong>of</strong> decreasing averageconcentrations in the solid) Zn, Ni, Rb, Cs, Cr, Co, U, Ge, Mo, V, Li, Cd,TI, Sm, Pb, Be, Eu, Tb, Ga, Ce, As, Cu, Lu, <strong>and</strong> Sc. Many<strong>of</strong> theseelementshave been cited in the literature as generally occurring in greaterconcentrations in eastern Paleozoic <strong>coal</strong>s <strong>and</strong> their <strong>ash</strong>es than in western<strong>coal</strong>s <strong>of</strong> Mesozoic <strong>and</strong> Terti ary-age (Abernathy, 1969; Gl uskoter et a1 . ,1977; Natusch et al., 1977; <strong>and</strong> Page et al., 1979). The averageconcentrations <strong>of</strong> Hf, Sb, Se, Ta, Th, W, <strong>and</strong> Yb in the <strong>fly</strong> <strong>ash</strong>es were notfound to correlate with <strong>coal</strong> type in this study.

This system is based on the chemicalcomposition <strong>of</strong> the solid waste <strong>and</strong> the pH <strong>of</strong> an askdistilled water mixture(I:) Seven <strong>of</strong> the nine Illinois Basin <strong>fly</strong> <strong>ash</strong>es were alkaline Modicsilts (Fig. 4). Fly <strong>ash</strong>es fitting into the Modic field have a sialiccornponent (% weight <strong>of</strong> Si02 + A1 203 + TiOz), which indicates that theseelements consist <strong>of</strong> a combination <strong>of</strong> from >48% to 88% <strong>of</strong> the total mass.The ferric cornponent (% weight <strong>of</strong> Fez03 + S03) is from 0 to 23%, <strong>and</strong> theCalcic component (CaO + MgO + Na?O + K20) is from 0 to 29%.
