Abstract

A series of detailed column sorption experiments have been conducted to investigate metal attenuation (Cd2+, Co2+, Cu2+, Mn2+, Ni2+, Zn2+) and acid neutralization in a synthetic wastewater by Fe-, Ti- and Al-containing industrial by-products. The industrial by-products comprised magnetite ore processing residue, titanium-containing blast furnace slag, blast furnace slag, steel slag, magnetite-containing titanium dioxide processing residue and red mud. The estimated range of metal sorption capacities for the six industrial by-products was: Cd2+ 278-6811 mg/kg; Co2+ 127-6052 mg/kg; Cu2+ 442-53566 mg/kg; Mn2+ 95-5594 mg/kg; Ni2+ 158-6213 mg/kg; and Zn2+ 151-6710 mg/kg. The acid neutralization capacity varied from 4.5-8.9 mol H+/kg for the six industrial by-products. Industrial by-products, particularly steel slag and red mud, are potentially useful for the amelioration of acid drainage, or the attenuation of heavy metals and acidity in mining or industrial wastewaters.
