===Manganese electrolysis===
During the [[electrowinning]] of manganese, the addition of [[selenium dioxide]] decreases the power necessary to operate the [[electrolytic cell|electrolysis cells]]. China is the largest consumer of selenium dioxide for this purpose. For every tonne of manganese, an average 2&nbsp;kg selenium oxide is used.<ref name="usgs">{{cite web|title= Selenium and Tellurium: Statistics and Information|url= http://minerals.usgs.gov/minerals/pubs/commodity/selenium/|publisher= United States Geological Survey|access-date= 2012-05-30|archive-date= 2012-05-08|archive-url= https://web.archive.org/web/20120508085217/http://minerals.usgs.gov/minerals/pubs/commodity/selenium/|url-status= dead}}</ref><ref>{{cite journal|doi= 10.1016/j.electacta.2011.06.111|title= Studies of the reduction mechanism of selenium dioxide and its impact on the microstructure of manganese electrodeposit|date= 2011|last1= Sun|first1= Yan|last2= Tian|first2= Xike|last3= He|first3= Binbin|last4= Yang|first4= Chao|last5= Pi|first5= Zhenbang|last6= Wang|first6= Yanxin|last7= Zhang|first7= Suxin|journal= Electrochimica Acta|volume= 56|issue= 24|pages= 8305–8310 |display-authors=3}}</ref> <!--http://www.asianmetal.com/report/en/2008mn_en.pdf-->
