nickel sulphide ore upgrading

Enhanced methods for nickel recovery from low-grade ores and ...

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.

Upgrading nickel in laterite ores by flotation - CORE

Nickel is sourced from sulphide and laterite ores. While 70% of the nickel resources are contained in laterites, these ores are often complex and expensive to treat using conventional methods. Therefore, upgrading the nickel content in laterite ores ahead of any recovery processes is economically desirable.

Sulfide Ores - an overview | ScienceDirect Topics

13.5 Heap Leaching of Nickel Sulfide Ore. An alternative to intensifying the rate of leaching of concentrates is to heap leach the whole ore. This has the significant advantage of eliminating the concentration of the sulfides, which is the step that has the lowest recovery on route from ore to metal. Nickel sulfide ores are processed by heap leaching in Sotkama, eastern Finland (Talvivaara, 2011 ).
