RECOVERY OF NICKEL IN LEACHING OF LATERITE ORES |
| 摘要 |
<p>The invention provides a process for the leaching of a laterite ore or concentrate for the recovery of value metals, at least one value metal being nickel. The laterite ore or concentrate is subjected to a leaching step in acidic mixed chloride solution to leach nickel from the laterite ore. Nickel is extracted with an oxime at a lower pH than other processes for extraction of nickel from solution, especially after separation of iron and cobalt values.</p> |
