A review on ruthenium recovery from ruthenium-containing waste catalysts

It is of special significance to recover ruthenium from spent ruthenium catalysts in China. The sources of ruthenium-containing waste generally include waste catalyst, nuclear waste, alloy materials, and so on. Based on the literature and relevant domestic patents, several important methods to recover ruthenium from the waste catalysts are described. and the advantages and disadvantages ofeach method are also analyzed. These methods are oxidation distillation, melting reduction precipitation, ion exchange, adsorption, capture, extraction. Among them, oxidation distillation is the most mature and widely used. Selective adoption method and extraction method are promising, because they have the advantages of high selectivity, high recovery rate and low pollution.
