Recovery of Rhenium from Low Concentrated Bioleaching Solutions by Solvent Extraction


Recovery of Rhenium from Low Concentrated Bioleaching Solutions by Solvent Extraction

Helbig, T.; Scharf, C.

The r4-project "Theisenschlamm" focuses on the recovery of elements of strategic economic importance (like Rhenium or Molybdenum). The first step within the research approach is bioleaching of the Theisenschlamm, which is a waste material of the former copper shale processing in the Mansfeld region (Germany). As a next process step the project partners investigate different element selective separation methods to recover the valuable elements from the bioleaching solution. An efficient rhenium recovery from synthetic (bioleaching) solutions is achieved using solvent extraction with teriary amines. It could be shown that rhenium can be enriched in the organic phase and that a good selectivity over zinc, copper, cobalt, germanium and iron(III) is obtained.
