  • how is nickel ore separated from nickel

    Nickel ore, which accounts for 73 percent of the world's overall nickel resources, has the tendency to transform into slurry during voyage, causing the vessel to lose balance and capsize. According to Intercargo, nickel ore is prone to a phenomenon called liquefaction, in which the water separates from the ore due to moisture and ever-changing temperature in the sea.

    1 天前· Nickel requires higher smelting temperatures (in the range of 1,350 °C [2,460 °F]) in order to produce an artificial nickel-iron sulfide known as matte, which contains 25 to 45 percent nickel. In the next step, iron in the matte is converted to an oxide, which combines with a silica flux to form a slag.
