RECOVERY OF SOLID MAGNESIUM SULFATE HYDRATE |
摘要 |
<p>A process for recovering solid magnesium sulfate hydrate from a source of magnesium sulfate in solution includes the steps of providing a source of magnesium sulfate in solution that is derived from part of a process associated with the leaching of a metal containing ore or concentrate; adding sulfuric acid to the magnesium sulfate solution to salt out the magnesium sulfate as magnesium sulfate hydrate crystals in a salting process, and partially diluting the sulfuric acid; recycling the diluted sulfuric acid for use in the process of leaching the metal containing ore or concentrate; and recovering the solid magnesium sulfate crystals.</p> |
