A study of millerite from Cu-Ni-PGE footwall veins, Sudbury, ON: crystal-chemistry, morphology, & geological implications
Millerite (-NiS) is a common accessory mineral in magmatic Cu-Ni-PGE deposits, such as those occurring in Sudbury, Ontario, Canada. In such localities, millerite develops as platy crystals, often forming large, cleavable masses. This is in stark contrast to the more widespread occurrence of …

An Investigation of Ni and Cu Isotopic Fractionation in Basal Duluth Complex Cu-Ni-PGE Mineralization, Northeastern Minnesota
Cu-Ni-PGE magmatic sulfide-style mineralization occurs along the western margin of the Duluth Complex in northeastern Minnesota. Previous studies have demonstrated a notable fractionation of 60Ni and 58Ni in terrestrial materials, including both primary and secondary phases, with a total range of …

Mineralogical effects on the dense medium separation of low grade nickel sulfide ore
… ores are mined, to increase the feasibility of mining such ores. Two nickel sulfide deposits were chosen as case studies in order to understand differences in DMS efficiency for different ores. The first is the Main Mineralised Zone (MMZ) of the Nkomati Nickel deposit in Mpumalanga, South Africa, …

Water Quality Impact on Flotation Response: A Focus on Specific Ions and Temperature
… the need to recycle process water within the mining industry. This recycling however causes an accumulation of ions in the process water which may affect plant processes since processing routes are water-intensive. Seasonal temperature differences affect the water quality through variation of …

Petrofabric investigation of the sulfide-rich basal zone of the Duluth Complex
… (SKI) of the 1.1 Ga Duluth Complex hosts significant Cu–Ni–PGE sulfide deposits concentrated within its basal contact zone. Although the geochemical signatures of these ores are well documented, the physical mechanisms responsible for focusing sulfur-rich melts remain unclear. This study …

Emplacement of sharp-walled sulphide veins during reactivation of impact-related structures at the Broken Hammer Mine, Sudbury, Ontario
Broken Hammer is a hybrid, Cu-Ni-Platinum Group Element (PGE) footwall deposit in the North Range of the ca. 1.85 Ga Sudbury impact structure. The sulphide vein system and associated low sulphide PGE mineralization were mined as an open pit operation over a 15-month period, providing a unique …
