Nickelcopper separation is performed at pH 12; thus, the nickel and copper concentrates were highly alkaline. Therefore, when the overflows of the copper and nickel concentrate thickeners and fines thickener were combined, the feed to the thickener overflow became alkaline. The process water and thickener overflow generally had lower temperature relative to the flotation feeds. This is to be ...

The Raglan concentrator flowsheet. Situated in the Nunavik territory of Northern Quebec, Canada, the Raglan nickelcopper mine is part of Falconbridge's Integrated Nickel Operations (INO). Commercial production began in 1998, following the investment of around C550m in the mine, concentrator and infrastructure. In June 2005, Falconbridge merged with its parent company, Noranda, with the ...
C. COPPER ORES FROM BIHAR Indian Copper Complex of Hindustan Copper Ltd., are working out the copper ore deposit in Mosabani and Surda areas and processing at their Maubhandar concentrator and smelter. In addition they have set up two more concentrators at Mosabani and Maubhandar. The copper ore contains appreciable amounts of nickel which is
2 days ago · Nickel processing Nickel processing Extraction and refining: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of highertemperature refractories and the increased cooling required to accommodate the higher operating temperatures in .
