Precious metals are widely being used in various industries because of their specific physical and chemical properties. Conventional hydrometallurgical 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 need a large volume of solution to be handled including metal-bearing solutions and organic solvents. In this talk, a biosorption-based recovery method is proposed as an alternative separation technology to overcome such a disadvantage. To make the proposed method competitive, required specification of sorbents is discussed. Especially, strategies for design of powerful biosorbents are suggested with some successful application cases. |
