  • Lateritic nickel ore deposits - Wikipedia

    Silicate type (or saprolite type) nickel ore formed beneath the limonite zone. It contains generally 1.5-2.5% nickel and consists largely of Mg-depleted serpentine in which nickel is incorporated. In pockets and fissures of the serpentinite rock green garnierite can be present in minor quantities, but with high nickel contents - mostly 20-40%.

  • Nickel Metal: It's Properties, History, Production Uses

    2019-07-28  Nickel is primarily extracted from the nickel sulfides pentlandite, pyrrhotite, and millerite, which contain about 1% nickel content, and the iron-containing lateritic ores limonite and garnierite, which contain about 4% nickel content. Nickel ores are mined in 23 countries, while nickel is smelted in 25 different countries.

    Nickel occurs occasionally free in nature but is mainly found in ores. Its chief ores are pentlandite and pyrrhotite (nickel-iron sulfides), garnierite (nickel-magnesium silicate), millerite (nickel sulfide) and niccolite (nickel arsenic). Nickel is taken from its ores by roasting and reduction processes which produce a metal of over 75% purity.

    2020-10-01  At present, laterite nickel ore contains more than 70% of nickel resources, while about 60% of industrial nickel production is derived from nickel sulphide ore [7,8]. Although nickel-laterite ore contains a large amount of nickel‑iron resources, low-grade nickel laterite ore has not been used effectively due to its complex mineralogical characteristics. With the sharp decline of nickel ...

These deposits develop from the mechanical and chemical breakdown of high temperature igneous rocks known as ultramafic rocks. These deposits consist of a predictable weathering profile that includes five “zones”: The un-weathered ultramafic bedrock, the weathered bedrock or “saprolite”, a clay-rich layer, limonite zonSee more on geologyforinvestorsPublished: 2014-06-12
