Recovery of sulfur and iron oxide from pyritic materials |
| abstract |
IRON SULFIDE BEARING MATERIAL IS LEACHED WITH HYDROGEN CHLORIDE AND THE LEACH SOLUTION IS MAINTAINED SATURATED WITH HYDROGEN SULFIDE BY INTRODUCING AND PASSING HYDROGEN SULFIDE THERETHROUGH. THE PH CONDITIONS ARE CON- TROLLED TO RECOVER IRON VALUES ALONE IN THE LEACH LIQUOR OR WITH ZINC AND LEAD VALUES. ZINC AND LEAD VALUES MAY ALSO BE RECOVERED UNDER CONTROLLED CONDITIONS. |
