The reprocessing of hydrometallurgical sulphidic tailings by bioleaching: the extraction of metals and the use of biogenic liquors
(Elsevier, 2022-01)
Mineralurgical and metallurgical processes generate a large amount of harmful residues. These wastes usually contain a considerable fraction of sulphides and a low percentage of target metals. Due to their characteristics, the ...

Polyurethane foam as biomass support for removal of thiosalts from flotation process water
(Elsevier, 2021-08-01)
Water recycling is a common practice in sulphide ore processing plants by flotation. Inherent thiosalts accumulation in process water often causes efficiency drop and environmental issues for wastewater discharging. Passive ...

Valorisation of a flotation tailing by bioleaching and brine leaching, fostering environmental protection and sustainable development
(Elsevier, 2019-10)
Flotation tailing is a problematic mining waste, because contains sulphides that exposed to oxidising conditions generate acidic drainage and the subsequent metal mobilisation. In this study, a flotation tailing produced ...

The BRISA process as a path for efficient copper recovery from waste PCBs
(Elsevier, 2021)
In the present work, a two-stage biohydrometallurgical process for copper extraction from waste PCBs is developed. The main goal of this study is to check whether to separate the chemical leaching of copper with ferric ...

Copper recovery from unground printed circuit board by biogenic ferric at high solid/liquid ratio
(Elsevier, 2022)
In this work, the recovery of Cu from large waste printed circuit board (PCB) pieces by biogenic ferric sulphate at high solid to liquid ratio was studied. PCB parts were packed in a column and biogenic ferric was constantly ...
