Bioleaching and chemical leaching as an integrated process ...

2007-5-1  Considering bioleaching and chemical leaching as integrated processes, the overall leaching time is reduced as compared to that observed by Pani et al. (2003) for the complete bioleaching of ZnS; nevertheless the residence time is still relatively large. As a result, this route would be most suitable for small expansions in RLE plants, such as those in the range of 20,000 zinc tons per year, without the

Abstract Two step leaching experiments were carried out to extract nickel, vanadium, and molybdenum present in spent refinery catalyst. A bioleaching process was applied in the first step. Pulp density, initial Fe(II) concentration, initial pH, particle size, and temperature were varied to optimize the bioleaching process. Ni, V, and Mo were leached out with maximum recoveries of 97%, 92% and ...

The bioleaching process can be fully integrated with downstream metals recovery processes. For example, solvent extraction and electrowinning (SX-EW) can be applied to produce LME A-grade copper cathode, and precipitation processes can be employed to produce metal intermediates (such as hydroxides, carbonates or sulfides).
