Selenium can be dissolved in cyanide to form selenium cyanide. Tellurium mineral decomposes the cyanide and absorbs the dissolved oxygen, thus affecting the cyanide leaching of gold [12]. The carbonaceous minerals (graphite, organic matter) in gold ore have the adsorption effects on dissolved gold, forming "preg-robbing effect" [13].

The optimised stepwise process (Scheme 13) involves the treatment of alkyl halides (or tosylates) with KSeCN, in situ generated from potassium cyanide and elemental selenium. The resulting selenocyanates are then converted into the corresponding diselenides, which are finally reduced to 1-alkaneselenols by using H 3 PO 2 as reducing agent.
