During the (bio)leaching both wanted and unwanted metals are dissolved.
The metals of interest are recovered and further processed into usable
metal half products like bars, sheets etc. However, often a (waste)
stream with dissolved residual metals and high salt concentrations
remains that must be treated in order to reuse the water or release into
Traditionally, the combined waste of the mines results in large basins
with high concentrations of metals remaining in a more or less unstable
form. These so-called tailings dam can be an environmental hazard,
posing a considerable liability risk for mining companies.
In WP3 of the BioMinE project we are looking into the application of
biotechnology to recover as much as possible of the valuable metals.
Technology will be developed or improved to remove remaining metals and
when required sulfate from the bleeds from the processes. The final goal
is to obtain as much as possible socio-economic benefits. Summarised,
the drivers of WP3 are as follows:
