Precious metals are widely being used in various industries because of their specific physical and chemical properties. Conventional methods for the recovery of low concentrations of dissolved precious metal ions from solution phases include solvent extraction, chemical precipitation and ion exchange. These methods have significant disadvantages, including incomplete metal recovery, high capital costs, high reagent and energy requirements, and other waste products that require disposal. In this talk, a sorption-based recovery method is proposed as an alternative separation technology to overcome such disadvantages. To make the proposed method competitive, required specification of sorbents is discussed. Especially, strategies for design of powerful sorbents are suggested with some successful application cases.
