Structural and electrical characterisation of silicon and other semiconducting nanoparticle networks for use in sensor and photovoltaic applications
… generated through incomplete oxidation of sulphidic ores, are primarily responsible for thiocyanate formation. In addition, thiocyanate generated during these processes has been identified to mobilise both base metals and precious metals, forming highly stable and soluble complexes with …

Formation of thiocyanate in bioleaching residues and its effect in PGM recovery
… generated through incomplete oxidation of sulphidic ores, are primarily responsible for thiocyanate formation. In addition, thiocyanate generated during these processes has been identified to mobilise both base metals and precious metals, forming highly stable and soluble complexes with …

Acid biodesulphurisation of coal discards using a heap leaching approach
… significant environmental risks. The presence of sulphidic minerals, particularly pyrite, in these wastes can lead to the formation of acidic runoffs, known as acid rock drainage (ARD), when exposed to moisture and oxygen. While physical separation can effectively remove sulphides from fine coal …

Evaluation of three carbon sources for the biological treatment of acid mine drainage through process modelling
… are the industries mining coal and metalbearing sulphidic minerals, which gives rise to the production of acid mine drainage (AMO). AMO is generated from both active and abandoned mining areas. The metal sulphides in the metal tailings are oxidised to produce large amounts of dissolved metals, …

A multifarious comparative ecotoxicological approach on a catchment scale from three mine wastelands for improved environmental management and risk assessment: integrating abiotic, biotic and agroecosystem approaches
… environmental impacts associated with mining of sulphidic minerals. To avert this, suitable handling of mine overburden material, waste rock, open pits and tailing storage facilities (TSF) is needed. This study addressed the risks associated with metal mobilization from the waste, including those …
