  • Nickel processing Extraction and refining Britannica

    From laterite ores. Being free of sulfur, laterite nickel deposits do not cause a pollution problem as do the sulfide ores, but they do require substantial energy input, and their mining can have a detrimental effect on the environment (e.g., soil erosion). The range of process options is limited by the nature of the ore.

    Ore Deposits. Typical nickel laterite ore deposits are very large tonnage, low-grade deposits located close to the surface. They are typically in the range of 20 million tonnes and upwards (this being a contained resource of 200,000 tonnes of nickel at 1%) with some examples approaching a billion tonnes of material.

  • Lateritic Bauxite Deposits Our Largest Source of

    Oct 17, 2019· Laterite is formed when heavy tropical rainfall results in intense weathering of rock and soil. After many millions of years what is left is called a “laterite”, which can be either iron-rich, or in extreme cases, aluminium-rich. Most of the world’s aluminium is mined from lateritic bauxite deposits.

    It also interferes with the processing of the ore as individual grains need to be crushed in order to liberate ore minerals from gangue intergrowths. Grades of cobalt in laterite deposits vary widely in the range 0.1 to 1.5% Co. Topography plays an important role in the formation of laterite deposits.

  • Bauxite The Aluminum Association

    Bauxite ore is the world’s primary source of aluminum. Bauxite is a rock formed from a reddish clay material called laterite soil and is most commonly found in tropical or subtropical regions. bauxite is broken up and taken out of the mine to an alumina refinery. Once mining is complete, the topsoil is replaced and the area undergoes

  • INCO R&D: Goro Laterite Development Canadian Mining

    Apr 01, 2002· The laterite nickel ore at Goro is composed of two layers–limonite and saprolite–between a cover of leached material and the bedrock below. The 10-20-m-thick cover has its own two layers: brittle iron oxide crust covers a high-hematite zone. Beneath these is the 10-m-thick limonite layer, which grades about 1.5% Ni.
