摘要： The present invention provides both reagents and a process for removing heavy metals from a caustic fluid stream by the addition of reagents which are not corrosive or deleterious. Specifically, the present invention is directed to removing heavy metals from a Bayer liquor in an aluminum processing plant. The reagents, dithiocarbamate and dithocarbonate groups, are added individually or in combination thereof to the Bayer liquor for the removal of heavy metals, such as zinc. The reagents form a complex with the heavy metal for the precipitation of the metal from the fluid stream. Once a complex is formed, the Bayer liquor is held in a quiescent state for a period of time sufficient for settling out of solution the precipitate. After settling out of solution, the precipitate is separated and removed and the Bayer liquor is then further processed into alumina.
