"The objective of the overall innovation project BiotaMet is to develop and market a climate-friendly nature-based more efficient 2-step bioleaching technology that would secure the supply of raw materials from EU’s local ores and mine wastes that due to strong organo-metallic complexes are missing cost-efficient metals extracting methods. The objective of the specific feasibility study named MetLeach that was performed via SME-Phase 1 was to evaluate the technological and economic possibilities in widening the usage of the innovative technology on vast underground resource - European polymetallic black shales containing organic compounds and on low-grade mine wastes.
The project addressed the possibilities to expand the market in EU of an innovative new metal extraction technology developed by Estonian SME. Using a new team of different microorganisms on the ore in a cooperation that results with the generation of methane gas and metals dropping into the water solution generates a new more cost-efficient way to extract metals from low-grade ores.
Simultaneously the European deposits of black shale ores contain significant reserves of base and highly valuable rare and precious metals (Mo, Re, V, Ni, Zn, Cu, Ag, Zn, Pb, Co, Bi, Au, Pt, Se, Pd, Sn, etc.) of which Europe is the main consumer in the World. As the conventional metallurgy methods are with low efficiency and negative environmental impact for recovering valuable metals from European black shales, the industry and scientists have turned to biohydrometallurgy.
The outcome of BiotaMet project is strongly supporting the second pillar from 3 pillars that are presented in The European Commission’s Raw Materials Initiative – foster sustainable supply of raw materials within the EU via cost-effective and climate friendly technologies thus boosting overall resource efficiency in the Union. The outcome is also supporting a third pillar of the given Initiative - Resource efficiency and supply of ""secondary raw materials"" through recycling, as technology being developed can be used to maximise the cost-efficiency of extracting metals form mine wastes and electronic waste"
