Black shales – an unconventional source of noble metals and rhenium

open access: yesЗаписки Горного института
The content of noble metals and rhenium in the Lower Paleozoic black shales of the eastern Baltic paleobasin in Russia was estimated. Shales are enriched in platinoids (PGM to 0.12 g/t) and rhenium (to 1.54 g/t).
