FLOTATION SEPARATION OF ARSENOPYRITE FROM PYRITE. |
摘要 |
<p>Arsenopyrite is separated from a mixture with pyrite by contacting the mixture with a sulfitic agent providing HSO3- ions at elevated temperature and pH below about 8 for a period sufficient to impart a selective depression property to the arsenopyrite. On addition of a collector the pyrite is rendered floatable, enabling froth flotation to achieve a concentrate rich in pyrite and tailings rich in arsenopyrite.</p> |
