There is growing interest in the bacterial leaching of low-grade ore bodies in the Australasian region. Operational aspects of local heap leaching have been described by Andersen and Allman (1968). The experimental approach to this process frequently employs the use of percolation leaching columns (Madsen et al., 1975; Bruynesteyn et al., 1977; Le Roux and Mehta, 1978; Murr and Brierley, 1978). The results to be presented arise from laboratory leaching studies on copper porphyry ores from Bougainville Island, Papua-New Guinea. The detailed mineralogy of these rock types have been described by Lawrence and Savage (1975). Espie (1971) has described the Bougainville Copper Project mining operation.
