Abstract

Thiobacillus ferrooxidans and Thiobacillus thiooxidans significantly enhances heazelwoodite (Ni3S2) dissolution. In pure cultures, heazelwoodite was more efficiently leached by T. ferrooxidans in the absence of alternative energy sources and in cultures supplemented with iron(II) and sulphur. In the other cultures, pure T. thiooxidans cultures reached greater extractions in the presence of iron(III). Under all experimental conditions, mixed cultures were more efficient than pure cultures. Nickel extraction in mixed cultures can be analysed as a cooperation of the mechanisms involved in the pure cultures of T. ferrooxidans and T. thiooxidans. (C) 2001 Elsevier Science Ltd.
