The demand for responsibly sourced cobalt has increased dramatically as a result of the global transition to ‘fossil-free’ electromobility. However, distribution, mineralogical expressions and mechanisms concentration Co in different types hydrothermal ore deposits remain poorly constrained, inhibiting resource assessments exploration. Here we report other metal concentrations ores from active ...

Tailings are a residual material stream produced in the mineral processing of ores. They may contain major sulphide content that increases risk acid rock drainage (ARD) but also host valuable metals. Tank bioleaching is technically viable method to treat tailings. However, significant pyrrhotite cause increased and oxidant consumption result longer retention times process. In this work, non-oxi...
