Kinetics of cupric leaching of pyrite in 4 M NaCl solutions Cinétique de la lixiviation cuivrique de la pyrite dans des solutions de NaCl 4M
(Taylor & Francis, 2020)
Cupric chloride leaching is an attractive alternative for the treatment of pyritic refractory gold ores. In this context, the kinetics of pyrite dissolution was studied in cupric chloride solutions containing 4 M NaCl. ...
Dynamic simulation of the carbon-inpulp and carbon-in- leach processes
(Brazilian Journal of Chemical Engineering, 2007)
Carbon-in-leach and carbon-in-pulp are continuous processes that use activated carbon in a cascade of large agitated tanks, which have been widely used to recover or concentrate precious metals in gold extraction plants. ...
Simulation study of the optimal distribution of cyanide in a gold leaching circuit
(Minerals Engineering, 2006)
The mineral industry has been using cyanidation to recover gold from ores for more than a century; however, a systematic study of the best reactant addition strategy in a cascade of agitated leaching tanks is not available ...

Initial Studies about Gold Leaching from Printed Circuit Boards (PCB's) of Waste Cell Phones
(Elsevier, 2015-02)
Excessive consumption of mobile phones, a decrease in their life time and therefore, an increase in the generation of this type of electronic scrap, is noted in recent years. Printed circuit boards (PCB´s) from waste cell ...
Dynamic Simulation of the Carbon-Inpulp and Carbon-In-Leach Processes

Gold recovery from waste electrical and electronic equipment by electrodeposition: A feasibility study
(Elsevier B.V., 2015-10-01)
Due to rapid technological progress, the replacement of electronic equipment is very often necessary, leading to huge amounts that end up as waste. Printed circuit boards (PCBs) constitute a unique section among Waste ...
Gold and silver cyanidation from a residue produced by leaching dead-roasted copper white metal
(2010)
The present work discusses the gold and silver recovery by cyanidation front I solid leach residue produced by a new alternative of processing copper matte or white metal. The leach residue contains mainly hematite, cupric ...
