| 简介 |
A hydrometallurgical method for lateritic nickel ore comprises leaching the raw material by means of a strong acid in high-pressure pipelines to improve the leaching rate of various valuable components in the raw material; adding a complexing agent to more effectively leach valuable components such as dissipated, scarce, rare-earth or noble metals from the raw material into the solution. The waste residue produced by reinforced leaching meets standards for raw materials of building materials, the leaching solution and waste water are recycled, so that no waste water is discharged in the entire process, thereby basically achieving comprehensive recycling of the raw material with no discharge of solid, liquid or gaseous waste and with zero emissions. |
