  • Direct extraction of nickel and iron from laterite ores

    1/12/20130183;32;1. Introduction. Over the past 30 years laterite ores have become increasingly more important as a source of nickel metal (Dalvi et al., 2004).Several methods of nickel extraction from laterite ores have been piloted and some were put into full operation, including acid leach with sulphuric, nitric and hydrochloric acids, ammonia leach and the pyrometallurgical process (Superiadi, 2007).

    After mining, nickel ores are further processed to upgrade their nickel contents from 1 4% typical of the ores to concentrates with grades in the range 10 20%. Concentration involves crushing the ore and separating nickel bearing from other minerals using various physical and chemical processing methods.

  • Nickel processing Britannica

    The mining of laterites is basically an earth moving operation, with large shovels, draglines, or front end loaders extracting the nickel rich strata and discarding large boulders and waste material. The ore is loaded into trucks at the face, as would be the case in an open pit, and hauled to the smelter.

  • Extraction of Nickel QS Study

    Main ore is Pentlandite; Nickel is extracted from ores through the Mond procedure, in which nickel oxides are purified throughout several steps into pure nickel metal. It is placed with hydrogen and carbon monoxide gases at 122 degrees Fahrenheit, which converts it to impure nickel. Nickel is also a magnetic metal below 653 degrees Fahrenheit.

  • 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 nickels use in litSee more on feecoLive Chat
