and high-tech metals but also high contents of organic matter that handicap metal recovery by conventional techniques. Three world class black shale deposits were chosen as targets of the R&D... biotechnological processes for "eco-efficient’’ exploitation of black shale ores. Such ores contain base, precious and "high-tech" metals (Cu, Ni, Zn, Ag, Co, Pt, Pd, V, etc.) but also high contents......
