The specific objectives established for BIOCriticalMetals are the following:

1. To sample and characterize mine waste tailings and associated microorganisms from tungsten and massive sulphide deposits from different climate contexts;

2. To assess the bioleaching process using microorganisms to mobilize critical metals W, In, Ga, Te and Mo from mine waste tailings for further processing (i.e. biosorption and accumulation);

3. To evaluate the bioaccumulation development for biosorptive leachate treatment with bacteria for W, In, Ga, Te, Mo;

4. To develop experimental reactors for selected cases focused on the use of microbial consortiums.
