RECYCLING OF SOLIDS IN OXIDATIVE PRESSURE LEACHING OF METALS USING HALIDE IONS |
| 摘要 |
The invention provides a recycling step in an oxidative pressure leaching process for recovery of metals using halide ions, in which a portion of the leached solids are recycled back to the feed to the autoclave, to allow two or more passes through the high temperature leaching step.
