  • Laterite Ore an overview ScienceDirect Topics

    Laterite Ore. Laterite ores are formed by the process of weathering and normally found in tropical regions where weathering extracts and deposits it in layers at varying depths below the ground surface. From: The Utilization of Slag in Civil Infrastructure Construction, 2016. Related terms: Iron Oxide; Titanium Dioxide; Ilmenite; Smelting; Leaching

  • Extraction of Nickel, Cobalt and Iron from Laterite Ores

    Lateritic ores are formed by prolonged weathering of ultramafic rocks. The laterite deposits exhibit graded layers of ore, with high iron, low nickel ore on top and low iron, high nickel ore below. The low iron (< 15 % Fe) ores containing 1.7 — 2.3% Ni are treated by pyrometallurgical processes to produce ferronickel or matte. High iron (> 35 % Fe) limonitic ores can be treated by high pressure leach using sulfuric acid. An alternative process

  • THE KINETIC PROFILE OF IRON DISSOLUTION FROM LATERITE

    Laterite ore was obtained from a mining site in South East Sulawesi Province. The ore was dried in the oven at 100 °C to remove the moisture prior to grinding and milling. The equipment to grind and mill the ore are jaw crusher and ball mill, respectively. The size of dried, ground, and milled laterite ore is 100 mesh (150 micron). The hydrochloric

  • Development of the iron-focused laterite (ARFe) process

    Laterite ores typically contain less than 2% nickel and consist of finely disseminated minerals, which are used to classify the ore into several key zones based on their degree of geological weathering and associated depth below ground level. Laterite resources commonly contain large quantities of iron-rich minerals, typically referred to as

  • Lateritic nickel ore deposits Wikipedia

    Limonite type laterites (or oxide type) are highly enriched in iron due to very strong leaching of magnesium and silica. They consist largely of goethite and contain 1-2% nickel incorporated in goethite. Absence of the limonite zone in the ore deposits is due to erosion. 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

  • Genesis of lateritic iron ore from banded iron-formation

    Lateritic weathering of metamorphosed Proterozoic banded iron-formation (BIF), locally named itabirite in Brazil, produced large deposits of iron ore. At the Capanema iron-ore mine in the Quadrilatero Ferrifero in Minas Gerais state (southeast Brazil), the BIF is a bedded metasedimentary rock composed essentially of layers of hematite/kenomagnetite alternating with layers of quartz.

  • RECOVERY OF NICKEL IN LEACHING OF LATERITE ORES

    A process for the leaching of a laterite ore or concentrate for the recovery of value metals, such values including iron, cobalt and nickel, comprising the steps of: a) subjecting laterite ore or concentrate to a leaching step with a lixiviant comprising hydrochloric acid and magnesium chloride to leach value metals from the laterite ore or concentrate, followed by a liquid/solids separation

  • Nickel processing Extraction and refining Britannica

    The specific processes taken depend on whether the ore is a sulfide or a laterite. In the case of sulfides, the reaction of oxygen with iron and sulfur in the ore supplies a portion of the heat required for smelting. Oxide ores, on the other hand, do not produce the same reaction heats, making necessary the use of energy from other sources for smelting.
