Roasting and Leaching Behavior of Nickel Laterite Ore
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. …

Copper Concentrates
Copper concentrates are solid mining products transported in bulk. The need for classifications of these materials, for the human health and environmental hazard categories set out in the HME criteria, was assessed following the UN-GHS 4th revision and the ICMM guidance (2013)1 on HME assessment of ores and concentrates.

Nickel processing | Extraction & Refining Techniques
Ores Sulfides. Canadian ores are sulfides containing nickel, copper, and iron. The most important nickel mineral is pentlandite, (Ni, Fe) 9 S 8, followed by pyrrhotite, usually ranging from FeS to Fe 7 S 8, in which some of the iron may be replaced by nickel. Chalcopyrite, CuFeS 2, is the dominant copper mineral in these ores, with small …
