The hydrogeochemistry of the Nickel Rim mine

31.01.2000· Since tailings deposition ended at the decommissioned Nickel Rim Ni–Cu mine near Sudbury, Ontario (), the water table has fallen from the tailings surface to about 1 m below the surface.The diffusion of gas-phase O 2 into the unsaturated zone has caused the oxidation of sulfide minerals in the shallow tailings. Sulfide oxidation is indicated by the microscopically observable

Mt Keith Nickel Project Tailings storage upgrade

Processing of nickel ore commenced at Mt Keith in 1994. To date, two conventional paddock storage type tailings cells have been used to store tailings, and the proponent has approval to construct an additional two cells. In 1990, a feasibility study into centralised thickened discharge disposal was initiated at Mt Keith, with subsequent engineering and environmental investigations for a "best

Nickel Investment Opportunities: 5 Junior Mining

"Nickel is primarily sold for its use as refined metal (cathode, powder, briquette, etc.) or ferronickel. Around 65% of Nickel consumed by the Western world is used to make austenitic stainless steel, 12 % goes into super alloys used in aerospace engineering and combustion turbines like those found in electric power generation stations. The remaining 23% of nickel is divided between alloy

The results of high-temperature XRD for the pyrrhotite tailings in air (Fig. 3 and Table 6) have shown that the phase of pentlandite remains up to 425 ºC, and pyrrhotite – 535 ºC. New

Mine Tailings - an overview | ScienceDirect Topics

Waters draining abandoned mines, mine spoils, and tailings deposits are often characterized by low pH and elevated concentrations of soluble metals (particularly iron) and sulfate (Table 3). These are generically referred to as AMD waters (or acid rock drainage in North America). Acidity in such waters derives from the presence of soluble aluminum, manganese, and iron (mineral acidity) as well

When floatability differences happens to the various nickel element of the raw ore, then nickel ore can be recoveried further from tailings after the copper and nickel been mixing flotation. Copper- Nickel Ore Flotation Process. When process copper-sulfide nickel ore, collector and frother will be used in order to better results. A basic

Already there are concerns over the environmental impact of the planned battery nickel factories, especially on how the plants could safely dispose of their waste, known as tailings. Developers of the Morowali plant said it should be possible to neutralise tailings by removing toxic materials from them and that they are currently preparing an environmental impact assessment.

Measurement of the Density of Sedimenting mine tailings by

mine tailings (i.e. finely crushed rock) with coarser particles. Calibration measurements were performed two types of sludge are shown in Table 1. The coefficients for water were calculated by combining the values for H and O interpolated from standard tables [8]. To differentiate between solids and water, the dual-source technique uses Eq. 4 and 5 where the denominator contains the
