Abstract Interest in low-grade Ni-laterite ores has increased recent years; however, the laterite process proven technically difficult and costly, development of alternative low-cost biotechnologies for Ni solubilization been encouraged. In this context, first time, a sample Brazilian ore was subjected to microbial bioleaching using heterotrophic Burkholderia sp. strain. Experiments were perfor...

a r t i c l e i n f o chemostratigraphy of two contrasting Deccan Traps weathering profiles – an ancient, deeply weathered laterite, and a younger (Quaternary), more moderately weathered saprolite – are used to reconstruct different aspects of basalt weathering. Precision of the HFSE analyses is demonstrated through a report of the long-term concentrations and ratios determined in United States...
