By electrochemical experiments, high metals removal has been achieved: in particular, by Zn and Mn electrodeposition, it was possible to achieve about 93-99% Zn and Mn removal (as MnO2), with a relatively low energetic consumption. The principle of the heavy metals selective sequential precipitation is the combined application of sodium hydroxide solution and hydrogen sulfide produced by sulfate-reducing bacteria. For the hydrogen sulfide production the sulphate-reducing bacteria of genus Desulfovibrio was used. The selective sequential precipitation process reaches the selective precipitation of chosen metals with 99% efficiency – Fe, As, Al and Mn in the form of metal hydroxides, Cu and Zn as metal sulfides.Consejo Nacional de Ciencia, Tecnología e Innovación Tecnológica - ConcytecengEDP SciencesE3S Web of Conferencesinfo:eu-repo/semantics/openAccesshttps://creativecommons.org/licenses/by-nc-nd/4.0/heavy metalsAcid Mine-1Drainage-1https://purl.org/pe-repo/ocde/ford#2.07.05-1Application of innovative remediation processes to mining effluents contaminated by heavy metalsinfo:eu-repo/semantics/conferenceObjectreponame:CONCYTEC-Institucionalinstname:Consejo Nacional de Ciencia Tecnología e Innovacióninstacron:CONCYTEC20.500.12390/877oai:repositorio.concytec.gob.pe:20.500.12390/8772024-05-30 15:59:38.414https://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccesshttp://purl.org/coar/access_right/c_14cbinfo:eu-repo/semantics/closedAccessmetadata only accesshttps://repositorio.concytec.gob.peRepositorio Institucional CONCYTECrepositorio@concytec.gob.pe#PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE#<Publication xmlns="https://www.openaire.eu/cerif-profile/1.1/" id="ef892460-3388-46ba-8b4b-27be71de61ab"> <Type xmlns="https://www.openaire.eu/cerif-profile/vocab/COAR_Publication_Types">http://purl.org/coar/resource_type/c_1843</Type> <Language>eng</Language> <Title>Application of innovative remediation processes to mining effluents contaminated by heavy metals</Title> <PublishedIn> <Publication> <Title>E3S Web of Conferences</Title> </Publication> </PublishedIn> <PublicationDate>2013</PublicationDate> <DOI>https://doi.org/10.1051/e3sconf/20130125001</DOI> <SCP-Number>2-s2.0-85016467601</SCP-Number> <Authors> <Author> <DisplayName>Ubaldini S.</DisplayName> <Person id="rp02319" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Luptakova A.</DisplayName> <Person id="rp02317" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Fornari P.</DisplayName> <Person id="rp02320" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Yoplac E.</DisplayName> <Person id="rp02318" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> </Authors> <Editors> </Editors> <Publishers> <Publisher> <DisplayName>EDP Sciences</DisplayName> <OrgUnit /> </Publisher> </Publishers> <License>https://creativecommons.org/licenses/by-nc-nd/4.0/</License> <Keyword>heavy metals</Keyword> <Keyword>Acid Mine</Keyword> <Keyword>Drainage</Keyword> <Abstract>The scope of the paper was to demonstrate the technical feasibility of the remediation processes by electrowinning and selective sequential precipitation, for toxic metals removal from acid mine drainage.
