In the processing of nickel typically lateritic ores or sulfidic ores are first crushed and milled to a fine powder Water is added to create a pumpable slurry which is treated with reagents during the flotation process in order to concentrate the nickel Smelting processes the concentrate further creating nickel rich matte while impurities are removed as slag
the storage and recycle of plant process water However there may be a need to treat bleed streams of some process effluents to prevent a buildup of various impurities Solid wastes from nickel sulfide ores often contain other metals such as copper and precious metals and con sideration should be given to further process ing for their recovery
Nickel deposits are typically found in low grade ores 1 2% nickel thus making it highly energy intensive to extract and refine the metal This leads to high emissions of greenhouse gases into the atmosphere and the use of large amounts of energy derived predominantly from fossil fuels 2
Brazil based Vale reported increased production of iron ore and nickel in the third quarter while nickel and copper production declined due to labour disruptions Iron ore production was up by % to million tonnes due to better weather in the Northern System increased production at the Vargem Grande dry processing plant and Itabira
The possibilities of extracting valuable components and producing selective good quality concentrates from hard to beneficiate crude ores are considered for the disseminated copper nickel ores from the Norilsk district The stated aim is achieved by a combined technology including beneficiation and hydrometallurgical processes Beneficiation is aimed at producing a rich copper concentrate and
Copper minerals and ores are found in both igneous and sedimentary mining of copper ores is carried out using one of two methods Underground and open pit mining If the ore is primarily sulfide copper minerals such as chalcopyrite the ore is crushed and ground to liberate the valuable minerals from the waste gangue minerals
the storage and recycle of plant process water However there may be a need to treat bleed streams of some process effluents to prevent a build up of various impurities Solid wastes from nickel sulfide ores often contain other metals such as copper and precious metals and consideration should be given to further processing for their recovery
