摘要 |
<p>To extract arsenic from smelting intermediates containing arsenic, to outside the system in stable form. A method of processing non-ferrous smelting intermediates containing arsenic comprises: a leaching step of performing oxidation leaching of a mixture slurry in the acidic region to obtain a leaching solution, the mixture slurry being a mixture of a non-ferrous smelting intermediate containing arsenic in sulfide form and a non-ferrous smelting intermediate containing arsenic and copper as metal; a solution adjusting step of adding an oxidation agent to the leaching solution to oxidize trivalent arsenic to pentavalent arsenic and obtain an adjusted solution; and a crystallizing step of converting arsenic in the adjusted solution to scorodite crystals.</p> |
