    摘要: Processes for the recovery of ruthenium from materials containing ruthenium or ruthenium oxides or from ruthenium-containing noble metal ore concentrates, with the steps of A. the introduction of the material into a highly alkaline alkali hydroxide melt in the presence of nitrate as oxidising agent with the formation of an oxidised melt residue with water-soluble ruthenate (RuO4)2-, B. the dissolution of the oxidised melt residue obtained in water, C. the addition of a reducing agent, D. the precipitation of the metals formed, can also be used for separating off selenium. Optionally, ruthenium is separated off by distillation, instead of precipitation, following step B, with the steps of 5C the treatment of the ruthenate-containing solution with an oxidising agent, 5D distilling off of the RuO4 obtained, 5E taking up of the RuO4 from step 5D in hydrochloric acid. By way of further subsequent purification steps, processes for the recovery of ruthenium targets are obtained.

    摘要: A method recovers noble metals from noble metal-containing compositions and includes steps of (i) providing a noble metal-containing composition containing an adsorption agent that is based on an inorganic material and is functionalized by organic groups and has at least one noble metal adsorbed to it, and (ii) ashing of the noble metal-containing composition provided in step (i) in order to adjust a residual carbon content of at most 10% by weight, relative to the total weight of the noble metal-containing composition after ashing, to obtain an ashed composition.
