| Özet |
| Twelve Turkish lignites and the corresponding ashes were leached in sulfuric acid (pH 1.0, 25 °C) for 14 days. Asphaltite from Silopi amended the coals. The conditions mimic treatment in the effluent from bioleaching of sulfidic mineral concentrates, but the results are equally valid for an isolated leaching process. The extended time meant that we approached equilibrium and maximum extraction. The coals have limited neutralizing capacity. H2SO4 (1.0–2.0 l, 1 M) was needed to stabilize 1 kg coal at pH 1.0 (liquid:solid ratio 10:1), but the coal-ashes required 18.0–24.0 l/kg dry solid, which is the neutralizing equivalent to CaO. Leaching of dominant inorganic phases consume acid, but our interest is merely to remove trace elements present as dopants. We removed large fractions of Mg and Mn, but Al, K and Na extractions were limited by the presence of stable minerals and bimetallic oxides. The formation of the … |
