  • nickel and cobalt ores: flotation 911 Metallurgist

    The maximum grade of nickel achieved by flotation is around 28% Ni. Problems Associated with Sulfide Mineral Flotation. The main problem encountered is selectivity of pyr rhotite and also in some cases chalcopyrite during flotation. A clean and satisfactory separation of pentlandite from pyrrhotite by flotation is difficult.

    Nickel was used industrially as an alloying metal almost 2,000 years before it was isolated and recognized as a new element. As early as 200 bce the Chinese made substantial amounts of a white alloy from zinc and a copper nickel ore found in Yunnan province. The alloy, known as pai t'ung, was exported to the Middle

  • Concentration of Useful Minerals from Asteroids

    We can therefore expect that asteroids contain a range of potentially useful minerals, including nickel iron, silicate minerals, and hydrated minerals or ices. We can also expect that these minerals will be mixed together, and will need to be separated from each other before they will be useful. We will therefore need

  • Mineral processing Energy EXchange

    Comminution, separation and concentrate drying account for most of the energy use in the mining and mineral processing sectors. Comminution is the most energy intensive of greenhouse gas emissions. These consequences are especially significant for the most production intensive metals, like copper, gold and nickel.

    Oct 9, 2017 The separation process for nickel is highly dependent upon the type of ore. Nickel sulphides, such as those found in the Canadian Shield and Siberia, are generally found deep underground, making them labor intensive and expensive to extract. However, the separation process for these ores is much

    Sulphide type nickel deposits are usually, although not always, found hundreds of metres underground resulting in an underground mining operation to extract them. Sulphide ores are much easier to process as they can be concentrated through physical separation by flotation. Laterite deposits are usually located closer to

    Nickel is mined by open pit or underground methods, then the rock is crushed and ground up, and the nickel sulphide ore is separated from the waste rock using froth flotation. At a refinery, the ore is then heated and treated with various chemicals to separate out the nickel. Nickel briquettes the final product of processing
