Review of Biohydrometallurgical Metals Extraction from

Most studies were focused on the extraction of manganese and only a few studies included the extraction of ancillary elements. Lee et al. investigated manganese, cobalt and nickel release by manganese-reducing bacteria (not identified). Efficient recovery of metals (75%80% after 48 h of incubation) was achieved during anaerobic leaching at

Solvent Extraction Solutions WOMP

A bleed stream of copper raffinate is neutralized to remove acid and copper and the cobalt is recovered by precipitation. The SX circuit comprises three extraction stages and two stripping stages. The raffinate bleed is treated through a two-stage iron removal circuit, with the first stage removing the majority of the acid, iron and manganese.
