More than 90% of zinc can be leached with the diluted H2SO4 solution at the temperature above 250\u00B0C. Fe(II) merges into the solution while most of Fe(III) remains in the solid residue. The hematite precipitation of the ferric sulphate solution was carried out. The reaction was ascertained to be first?order with respect to Fe(III). The apparent kinetic constant was determined to be 0.01 min-1." . . . "5"^^ . "Vallov\u00E1, Silvie" . "2009-06-04+02:00"^^ .
