  • Processing of Nickel Laterite Ores on the Rise

    The Move to Nickel LateritesLateritic Nickel Ore ProcessingConclusionSulfides have long supplied the bulk of the global appetite for nickel. But dwindling resources combined with the need to mine at greater (and subsequently less economic) depths to obtain sulfide ores has many miners looking at nickel laterites. Additionally, nickel is expected to see growth in demand as developing economies spur a greater need for stainless steel. Similarly, demand is expected to grow as a result of nickel’s use in lit在feeco上查看更多信息
  • High Quality (and Safe) Nickel Plating : 7 Steps (with

    Nov 02, 2013· Nickel plating can be used for a variety of different things. It creates a corrosion resistant coating that will protect the base metal from oxidizing and rusting. It is frequently used in processing to prevent contamination with iron. It can increase the hardness and thus the durability of mechanical parts and tools.

  • Electroplating Process Steps your electrical guide

    For nickel plating, the solution is made of 180 240 gm of nickel sulfate, 36 gm of nickel chloride and 24 gm of boric acid per 1000 cc of solution. The anode is of pure nickel. Nickel does not deposit well on iron and steel articles. Therefore, the article is first coated with a film of copper and then nickel is deposited on the copper plating.

    SectionsIntroductionPal and Caron ProcessesSherritt Gordon ProcessNickel Chloride ProcessExtraction by Chelate FormationBibliographyThe nickel and cobalt metallurgy processes begin with an initial treatment of the mineral, re-concentrating it through crushing and flotation/gravity and obtaining a “speiss”, rich in cobalt and nickel. The process begins by adding the sulfide-associated mineral to a reactor with sulfuric acid and pressurised air. This procedure removes the sulphides to obtain nickel (II) sulfate and cobalt (II) sulfate in solution. In this first dissolution stage, the sulfide is removed.
