Silver recovery by ion exchange |
| abstract |
The present invention according provides a method of recovering silver from silver containing halide solutions, comprising the steps of: (a) providing an ion exchange column comprising a weak anion exchange resin; (b) introducing the silver containing halide solution to the ion exchange column to absorb silver in the weak anion exchange resin; (c) washing the loaded ion exchange resin with a first washing solution to rinse off absorbed zinc and optionally at least part of copper; (d) washing the loaded ion exchange resin with a second washing solution to rinse off remaining copper; and (e) optionally washing the loaded ion exchange resin with a third washing solution to rinse off absorbed lead; and (f) eluting the loaded ion exchange resin with an eluent to remove silver from the resin and to obtain a silver containing solution. |
