Degradation of cyanides in wastewater from gold mining: A review of literature
(ARPN Journal of Engineering and Applied Sciences, 2019)Among the persistent chemical compoundsin the residual discharges are the highly toxic cyanides used in the industrial sector and in particular the mining industry for the extraction of gold, frequently appearing in low ... -
Enhancement of the adsorption of hexacyanoferrate (III) ion on granular activated carbon by the addition of cations: a promissory application to mining wastewater treatment
(Corporación Universidad de la Costa, 2020-07-27)The influence of the addition of cations on the adsorption of [Fe(CN)6] 3− on granular activated carbon (GAC) was evaluated. The tests were performed at three pH values (3, 8.2, and 13) to determine the repulsion or ... -
Ultraviolet light-mediated activation of persulfate for the degradation of cobalt cyanocomplexes
(Universidad de la Costa, 2020-03-06)The ultraviolet light activation of persulfate (PS) was evaluated for the degradation of cobalt cyanocomplexes, which are considered as some of the most recalcitrant compounds present in mining wastewater. The influence ...
