摘要 |
<p>A process for recovering zinc from a zinc containing material, the process including the steps of: leaching the zinc containing material with an alkaline lixiviant comprising an aqueous mixture of NH3 and NH4CI, or ionic equivalent, having a NH4CI concentration of between about 10g/L and about 150g/L H20 and a NH3 concentration of between 20g/l H2O and 250 g/L H2O, to produce a zinc containing leachate; stripping ammonia from the leachate to produce a stripped liquor which includes a zinc containing precipitate, the stripped liquor having a NH3 concentration of between 7 and 30g/L H2O; and recovering the zinc from the stripped liquor.</p> |
