Document Type and Number:
Japanese Patent JP2014511943
Kind Code:
A
Abstract:
The invention relates to the provision of noble metal-containing mixtures for a process for processing them by heating the mixture, preferably for processing them by means of an ashing process. This provision is characterized by the following measures: (a) moistening of the noble metal-containing mixture to be processed, (b) introduction of the moistened noble metal-containing mixture into at least one container which serves as diffusion barrier for water, and (c) introduction of the loaded container into a heat-resistant chamber together with at least one upper refractory mat. The noble metal-containing mixture is preferably moistened in the presence of a porous material and the chamber is closed by means of a heat-resistant covering. The invention further provides a processing process comprising the provision of noble metal-containing mixtures and also the heat-resistant chamber loaded with noble metal-containing mixtures itself. The process of the invention enables simple, clean recovery of noble metals in high yield from noble metal-containing mixtures.
