Abstract

Procedure for de-dessensification of speisses and similar materials, characterized by a heating of the crushed speiss in a temperature range of 500-800º, preferably between 600-700º, with calcined lime, moving it at the same time to air for the formation of arsenate calcic; the sintering of the product of roasting with soda and leaching with water of the formed sodium arsenate, as well as the elimination of the residual arsenic content (together with copper and nickel) by dilute sulfuric acid, from the residue of the soda lye, the process also comprising the operations of precipitation with soda solution of the metals dissolved in this way and heating of the precipitate with soda and water leaching of the formed sodium arsenate.
