Nickel Ores Process

The Direct Nickel Process DNi is an atmospheric hydrometallurgical processing route designed to treat all types of nickel laterite ores in a single flow sheet to produce a number of final saleable products. The key to the Process is the use of nitric acid as the leaching agent and the subsequent use of a patented recovery and recycling process.

    Mar 29 2021 Abstract Nickel is mostly extracted from sulfide ores however laterite ores account for over 60 pct of all nickel resources in the world and despite its predominance there is no well-established process to extract nickel from such ores. Nickel in laterites is hosted in many different compounds such as oxides hydroxides and silicates minerals. The sulfation-roasting-leaching process has.

    Whether high-grade or low-grade nickel ores need to be processed after mining in order to upgrade their nickel content from 1-4 Ni to 10-20. Concentrating the nickel ores usually takes place close to the mine site and involves chemical and physical processes to crush the ore and separate the nickel-bearing and gangue minerals.
