Precious metal refining services
Spent catalysts containing precious metals are sent to a metals refinery where the precious metal is extracted from the catalyst. The catalyst is destroyed in this process. The metals refinery produces solutions of precious metal salts that are subsequently used in the production of fresh catalysts.
This recycling minimizes precious metal loss. Evonik takes care of the entire precious metal cycle, from management of the precious metal account to coordination of refining activities. Evonik has a well established global network of metal refiners for recovery and refining of precious metals. This process is transparent to the customer, for whom Evonik is simply a convenient one-stop service point for all his refining needs. Our web site carries an interactive calculation tool. Taking the entire precious metal cycle and catalyst productivity into account, this web-based tool gives you an impression of the value that catalysts from Evonik can deliver.
