Bioleaching

Bioleaching is leaching where the extraction of metal from solid minerals into a solution is facilitated by the metabolism of certain microbes microbes Bioleaching is a process described as the use of microorganisms to transform elements so that the elements can be extracted from a material when water is filtered

Dubnium

Surprisingly the behavior on extraction from mixed nitric and hydrofluoric acid solution into methyl isobutyl ketone differed between dubnium tantalum and niobium Dubnium did not extract and its behavior resembled niobium more closely than tantalum indicating that complexing behavior could not be predicted purely from simple
