Addendum to “Process development for elemental recovery from PGM tailings by thermochemical treatment: preliminary major element extraction studies using ammonium sulphate as extracting agent” [Waste Manage. 50 (2016) 334–345]
(Elsevier, 2017)In a recent paper, a promising two-stage process for the extraction of major elements from Platinum Group Metals (PGM) was presented (Mohamed et al., 2016). This process involved solid-solid thermochemical treatment of ... -
Ammonium sulphate and/or ammonium bisulphate as extracting agents for the recovery of aluminium from ultrafine coal fly ash
(Elsevier, 2017)We recently showed that the selective extraction of aluminium from the amorphous phase of a South African ultrafine coal fly ash can be achieved via thermochemical treatment with ammonium sulphate for 1 h followed by aqueous ... -
Process development for elemental recovery from PGM tailings by thermochemical treatment: preliminary major element extraction studies using ammonium sulphate as extracting agent
(Elsevier, 2016)Mine tailings can represent untapped secondary resources of non-ferrous, ferrous, precious, rare and trace metals. Continuous research is conducted to identify opportunities for the utilisation of these materials. This ...
