Abstract: This invention relates to a method for toxicity comprehensive elimination of chrome residues, comprising adding water to chrome residues, wet-grinding the same to a thick liquid, letting it react with dilute hydrochloric acid, and letting the filtrate obtained react with an additive containing barium, with sulfuric acid or magnesium sulfate, and with cream of lime or soda, so as to realize a comprehensive extraction and utilization of various elements. The hydrochloric acids can be circulated, and the filter residues can be used for iron-smelting and brick-making. By means of this method, it is possible not only to completely and permanently eliminate the toxicity of the residues, but also to realize a comprehehsive utilization of the residue resources.
