Recovery of lead and cadmium ions from metal-loaded biomass of wild cocoyam (Caladium bicolor) using acidic, basic and neutral eluent solutions
(Pontificia Universidad Católica de Valparaíso, 2006)
Metal sulfide precipitation: Recent breakthroughs and future outlooks
(MDPI, 2021)
The interest in metal sulfide precipitation has recently increased given its capacity to efficiently
recover several metals and metalloids from different aqueous sources, including wastewaters
and hydrometallurgical ...
Selective electrochemical recovery of gold and silver from cyanide aqueous effluents using titanium and vitreous carbon cathodes
(Elsevier Science BvAmsterdamHolanda, 2004)
Study of a pilot plant for the recovery of metals from spent alkaline and zinc-carbon batteries with biological sulphuric acid and polithionates production.
(Planta Piloto de Ingeniería Química, 2014-04)
The recovery of Zn and Mn from spent alkaline and Zn-C batteries with a biohydro-metallurgycal process was studied in a pilot plant that consists in an air lift bio-reactor with a sulfur packed bed where Acidithiobacillus ...
Biosorption of chromium(III) by Sargassum sp biomass
(Univ Catolica De ValparaisoValparaisoChile, 2002)
Changing the conventional clarification method in metal sulfide precipitation by a membrane-based filtration process
(Elsevier, 2021)
The metal sulfide precipitation process is a widely studied technology used to recover metals or remove pollutants from different aqueous sources. However, the conventional clarification stage used to separate the generated ...
Recovery of metallic markers sprayed on soybean plants
(2015-01-01)
To understand aspects related to the application of plant protection products, the analysis of spray deposits using metallic markers is a simple and low cost alternative. However, choose the appropriate marker is a challenge. ...
Sulfate removal rate and metal recovery as settling precipitates in bioreactors: Influence of electron donors
(Elsevier B.V., 2021-02-05)
Four down-flow structured bed bioreactors were operated targeting biological sulfate-reduction and metal recovery. Three different electron donors were tested: glycerol (R1), lactate (R2), sucrose (R3), and a blend of the ...
Enhanced bio-recovery of aluminum from low-grade bauxite using adapted fungal strains
(2020-01-01)
Filamentous fungi have been proved to have a pronounced capability to recover metals from mineral ores. However, the metal recovery yield is reduced due to toxic effects triggered by various heavy metals present in the ...
Towards field trace metal speciation using electroanalytical techniques and tangential ultrafiltration
(2016-05-15)
In this work we propose a trace metal speciation methodology to determine the total, free and ultrafiltered (<1 KDa) metal fractions using electrochemical methods (SCP and AGNES) and tangential ultrafiltration (UF) experiments ...
