Mineralization of cyanide originating from gold leaching effluent using electro-oxidation: multi-objective optimization and kinetic study
(SPRINGER, 2020-01-01)
Abstract: This study examines the electro-oxidation (EO) of cyanide originating from an industrial plant´s gold leaching effluent. Experiments were carried out in a laboratory-scale batch cell reactor. Monopolar configuration ...

Leaching of pure chalcocite with reject brine and mno2 from manganese nodules
(2020-11)
Chalcocite (Cu2S) has the fastest kinetics of dissolution of Cu in chlorinated media of all copper sulfide minerals. Chalcocite has been identified as having economic interest due to its abundance, although the water ...
Avaliação de espécies metálicas presentes em materiais construtivos na deposição úmida
(Universidade Tecnológica Federal do ParanáCuritibaBrasilBacharelado em QuímicaUTFPR, 2016-06-23)
The trace metals are a great environmental problem, for all environment inclusive the human being. Those species can bio accumulate in trophic chain. At this context, the constructive materials are made by inorganic raw ...

The effect of chloride ions and A. ferrooxidans on the oxidative dissolution of the chalcopyrite evaluated by electrochemical noise analysis (ENA)
(2009-12-28)
It is believed that the dissolution of chalcopyrite (CuFeS2) in acid medium can be accelerated by the addition of Cl- ions, which modify the electrochemical reactions in the leaching system. Electrochemical noise analysis ...

Manure plume modeling in feedlot pen soils
(Springer Verlag Berlín, 2019-10)
The generation of large amounts of manure by confined cattle feeding operations (feedlot) in reduced areas is a concern due to its potential to act as pollutant for ground and surface water. Studies have revealed that ...
