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.
Nickel Mines stock opened the day at A$1.03 after a previous close of A$1.04. The latest price was A$0.99 (25 minute delay).
