A green electrorefining process for production of pure lead from methanesulfonic acid (MSA) medium was studied. The conductivities of lead - MSA solutions have been measured and modeled to characterize the electrorefining medium. The effects of current density, electrode spacing, electrorefining temperature, lead concentration, free-MSA concentration and electrorefining time on the electrorefining process were investigated. The cell voltage and specific energy consumption of the electrorefining process increase with an increase of current density, electrode spacing and electrorefining time, and decrease with an increase of electrorefining temperature, lead concentration and free-MSA concentration. The operating parameters of the electrorefining process for production of pure lead from MSA medium in this study have a widely acceptable range as follows: current density 150–250A/m2, electrode spacing 3.0–6.0cm, electrorefining temperature 293.5–313.5K, lead concentration 60–150g/L and a free-MSA concentration 100g/L. The cathodic current efficiency was in excess of 99% and the specific energy consumption was below 110kWh/t-Pb. The lead content of the cathodic lead was in excess of 99.99%.</description><identifier>ISSN: 1383-5866</identifier><identifier>EISSN: 1873-3794</identifier><identifier>DOI: 10.1016/j.seppur.2016.06.050</identifier><language>eng</language><publisher>Elsevier B.V</publisher><subject>Conductivity ; Current density ; Current efficiency ; Electrodes ; Electrorefining ; Energy consumption ; Lead ; Lead (metal) ; Mathematical model ; Mathematical models ; Methanesulfonic acid ; Voltage</subject><ispartof>Separation and purification technology, 2016-10, Vol.170, p.199-207</ispartof><rights>2016 Elsevier B.V.</rights><lds50>peer_reviewed</lds50><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c521t-13e37637aa9ca79307f6270b4d0e801339eca6e996c8163d66869db9cc0b32bd3</citedby><cites>FETCH-LOGICAL-c521t-13e37637aa9ca79307f6270b4d0e801339eca6e996c8163d66869db9cc0b32bd3</cites><orcidid>0000-0002-0027-2095</orcidid></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktohtml>$$Uhttps://www.sciencedirect.com/science/article/pii/S1383586616308760$$EHTML$$P50$$Gelsevier$$H</linktohtml><link.rule.ids>314,776,780,3537,27901,27902,65306</link.rule.ids></links><search><creatorcontrib>Jin, Bingjie</creatorcontrib><creatorcontrib>Dreisinger, David B.</creatorcontrib><title>A green electrorefining process for production of pure lead from methanesulfonic acid medium</title><title>Separation and purification technology</title><description>•The conductivities of lead - MSA solutions were investigated.•A mathematical model for the conductivities of lead - MSA solutions was developed.•Electrorefining process for production of >99.99% lead from MSA medium was studied.•The operating parameters of electrorefining process have a widely acceptable range.•The CCE and SEC were >99% and <110kWh/t-Pb, respectively.
