摘要： Provided is a process for the comprehensive recovery of metal cobalt, ruthenium and aluminum from a waste catalyst Co-Ru/Al 2 O 3 in a Fischer-Tropsch synthesis. First, a waste catalyst is subjected to hydrocarbon removal, and reduction treatment, to effectively separate a cobalt slag in an alkali fusion step, and then the cobalt slag is subjected to the steps of acid leaching, cobalt precipitation with oxalic acid or ammonium oxalate, reduction of cobalt oxalate, dissolution of metal cobalt with nitric acid, etc., to obtain Co(N0 3 ) 2 ·6H 2 O. A ruthenate which is dissolved by steps such as alkali fusion, and leaching with deionized water, is subjected to the steps of reduction with ethanol, dissolution with concentrated hydrochloric acid, distillation under reduced pressure, etc., to obtain a ²-RuCl 3 ·xH 2 O product with a high purity. Aluminum hydroxide is prepared from a meta-aluminate solution by CO 2 carbonation, by controlling the parameters such as reaction temperature, flow rate of CO 2 , pH value at the end point of the reaction, etc., and the aluminum hydroxide is calcined to obtain aluminum oxide with a product quality achieving the quality requirements of first-class aluminum oxide in the Chinese national standard. The resulting product has a high yield, wherein cobalt is ‰¥ 97%, ruthenium is ‰¥ 95%, and aluminum is ‰¥ 92%.

摘要： The method of the invention provides means of destroying highly stable metal cyanide ions found in a solution, and converting the cyanide to harmless by-products. Contrary to conventional methods which merely complex the cyanide into a mechanically or physically removable complex, the present method destroys the cyanide found in the sample. The invention is directed to a method of destroying cyanide comprising providing a highly alkaline solution containing a metal cyanide ions; and subjecting the solution to electro-oxidation.
