Nickel Mining and Processing: Everything you Need to Know

Apr 10, 2014 ... Dating back to 17th century Germany, nickel was discovered in a red-colored ore that German miners believed was copper. When their analyzation revealed it to be something else, they dubbed the material “kupfernickel”, which means “Old Nick's Copper” or false copper. It wasn't until nearly 200 years...

Beneficiation of low-grade weathered nickel sulfide ore for ... - Cetem

In this paper, an alternative beneficiation process was developed to recover nickel minerals from low- grade weathered ores. The studied sample, 0.3% Ni grade, is essentially composed of nickel sulfides. (pyrrhotite and pentlandite); magnetite and silicates (mostly talc and amphibolites) are the primary gangue minerals.
