Recycling of solids in oxidative pressure leaching of met-als 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. |
