WANG, C.; LI, S.; WANG, H.  and  FU, J.. Selenium minerals and the recovery of selenium from copper refinery anode slimes. J. S. Afr. Inst. Min. Metall. [online]. 2016, vol.116, n.6, pp.593-600. ISSN 2411-9717.  http://dx.doi.org/10.17159/2411-9717/2016/v116n6a16.

Since it was first identified in 1817, selenium has received considerable interest. Native selenium and a few selenium minerals were discovered several decades later. With the increasing number of selenium minerals, the occurrence of selenium minerals became the focus of much research. A great number of selenium deposits were reported all over the world, although few independent selenium deposits were discovered. Selenium is obtained mainly as a byproduct of other metals, and is produced primarily from the anode mud of copper refineries. This paper presents a comprehensive review of selenium minerals, as well as the treatment of copper refinery anode slimes for the recovery of selenium. Our focus is on the selenium minerals, including their discovery and occurrence, and the distribution of selenium resources. In addition, the main methods of recovering selenium from copper anode slimes are summarized.

Keywords : selenium; selenium minerals; anode slimes.
