METHOD OF LEACHING COPPER AND ARSENIC FROM COPPER DROSS |
摘要 |
<p>A process for leaching copper and arsenic from copper dross containing copper arsenide and separated from molten lead bullion comprises leaching the dross with an aqueous ammoniacal solution containing arsenate as the predominant anion under oxidizing conditions to obtain a leachate, removing copper from the leachate to obtain a raffinate and re-cycling raffinate to the leaching stage, and removing a bleed of raffinate from the circuit and precipitating a substantially insoluble arsenic compound from the raffinate bleed to remove arsenic from the circuit.</p> |
