Am. Fallman, Leaching of chromium and barium from steel slag in laboratory and field tests - a solubility controlled process?, WASTE MAN, 20(2-3), 2000, pp. 149-154
Differences in concentrations in leachates and leaching conditions were fou
nd in laboratory and field tests on electric are furnace steel slag. Solid
phases were assumed to control the leachate concentrations of chromium and
barium. Geochemical modelling was used to indicate solubility controlling s
olid phases. The mineral BaSO4(c) and solid solutions of Ba(S,Cr)O-4 were p
redicted to control the concentrations of barium and chromium in the leacha
tes, respectively. These solids were not expected to be present as primary
minerals in the steel slag but were rapidly formed, within 6 h. (C) 2000 El
