laterite nickel ore

    Lateritic nickel ore deposits, Processing of Nickel Laterite Ores on the RiseNickel processing, From laterite or 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 (eg, soil erosion) The range of process options is limited by the nature of the oreThe nickel laterite challenge, Jun 21, 2012· Nickel occurs in essentially two ore types; magmatic sulphides and ('wet' or 'dry') laterit The sulphides typically are found hundreds of metres below ground with ,Nickel Laterite, Nickel Laterite Groundradar is the world leader in ground penetrating radar applications to nickel laterite exploration and resource definition Staffs have conducted large-scale radar projects on over 60 deposits on six continents, in environments ranging from the Amazon jungle to ,Ni, May 26, 2011· Until now, the world nickel supply has been predominantly from sulfide deposits According to Gleeson and others (2003), Dalvi and others (2004), and Mudd (2010), laterites contain about 70 percent of world nickel resources, have been mined for more than 100 years, and account for about 40 percent of world nickel production.

    Impacts of Laterite Mining of Nickel and Iron Ores on ,, p 2 Impacts of Laterite Mining of Nickel and Iron Ores on Watersheds PREMISE Open pit, contour or strip mining of laterites involves removing 1 to 2 meters of topsoil to be able to extract the laterite, limonite and saprolite deposits which occupy the soil strata from 3 to 25 meters below the groundNickel Statistics and Information, The bulk of the nickel mined comes from two types of ore deposits: laterites where the principal ore minerals are nickeliferous limonite [(Fe,Ni)O(OH)] and garnierite (a hydrous nickel silicate), or; magmatic sulfide deposits where the principal ore mineral is pentlandite [(Ni,Fe) 9 S 8]lateritic nickel ore deposits, Lateritic nickel ore deposits chemeurope Typical nickel laterite ore deposits are very large tonnage, lowgrade 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 Thus, typically, nickel laterite ore deposits contain ,Laterite | geology | Britannica, nickel processing: Laterites Other important classes of ore are the laterites, which are the result of long weathering of peridotite initially containing a small percentage of nickel Weathering in subtropical climates removes a major portion of the host rock, but the contained nickel ,Nickel Laterite's Integral Role in the Coming Nickel Boom ,, Sep 13, 2018· Currently, the sulphide ore mainly feeds class 1 nickel users, and the laterite ores mainly feed the stainless steel industry (which, by the way, currently accounts for 2/3 of the global nickel demand) Nickel Laterite Ore Processing Nickel laterite ore processing depends on the zone from which the ore is mined.

    Treatment of Nickel, 1 Nickel and cobalt can usually be solubilized from laterites using sulphuric acid at atmospheric pressure, just below boiling point However, this generally requires a massive quantity of acid, which can render the process uneconomic The main reason for this is that for limonitic ores in particular, theProduction of ferronickel from nickel laterites in a DC ,, a) laterite ore fines and dusts (even less than 100 µm), b) partially calcined laterite ores, and c) nickel-containing slags Tests were conducted in a 50 kW furnace with an outside diameter of 600 mm, and a refractory lining thickness of 114 mm The refractory material had a 96% MgO contentHIGH PRESSURE SULPHURIC ACID LEACHING OF LATERITIC ,, from the lateritic nickel ore sample With the increase of acid/ore ratio, dissolution ratio values of Ni and Co increased up to acid/ore ratio of 03, and above 03, lower dissolution ratio values were obtained Although leach residues obtained after leaching at acid/ore ratio of 03 contained mainly hematite, quartzNickel Laterite Ore Deposits: Weathered Serpentinites ,, Nickel laterite ores account for over 60% of global nickel supply They are the product of intensive deep weathering of serpentinites under humid tropical conditions Nickel is concentrated to over 10 wt% and is hosted in a variety of secondary oxides, hydrous Mg silicates and smectitFigure 1 from Nickel laterite processing technologies ,, A review has been completed of current and proposed processing technologies for nickel laterite or Although future supplies of nickel depend on laterite ores, their processing is inherently energy intensive and expensive as, unlike sulphide ores, they cannot be significantly upgraded, meaning the entire ore needs to be treated in the process.
