Abstract

Procedure for separating selenium from mercury in its recovery from the raw minerals that contain metals, heating the raw minerals in oxidizing conditions mixed with additives, which in the heat treatment carried out under these conditions, agglomerates the selenium in an easily soluble form while Mercury is distilled, after which the dissolution treatment is carried out with dilute acid and the dissolution residue is separated from the solution from which the selenium is recovered, further characterized by the addition of alkaline earth metal compound to the basic crude mineral that forms with selenium in the heat treatment alkaline earth selenites easily soluble.
