    • The present invention concerns a process for the recovery of a noble metal from an inorganic and/or organic residue in the form of a tellurium amalgam characterised by adding a solvent having a boiling point above 120°C to the residue, removing by distillation water and other residual solvents having boiling points below the boiling point of the added solvent, adding the tellurium or reducible tellurium compound, and then refluxing at atmospheric pressure before separating the amalgam of the noble metal.
      The process of the present invention also allows the simultaneous recovery of the tertiary phosphine as its oxide from a residue containing a tertiary phosphine by the further stages of concentrating the mother-liquors remaining after separation of the amalgam of the noble metal, recovering the added high boiling point solvent and isolating the tertiary phosphine in the form of its oxide by precipitation with water.
    • 本发明涉及从碲汞齐形式的无机和/或有机残余物中回收贵金属的方法,其特征在于向残余物中加入沸点高于120℃的溶剂,通过蒸馏水除去和 沸点低于添加溶剂沸点的其他残留溶剂,添加碲或可还原碲化合物,然后在大气压力下回流,然后分离出贵金属的汞齐。 本发明的方法还允许从含有叔膦的残余物中同时回收作为其氧化物的叔膦,通过进一步浓缩在分离贵金属的汞齐之后留下的母液的步骤,回收添加的高 沸点溶剂,并通过用水沉淀分离其氧化物形式的叔膦。
