Salinity in Nickel Laterite Processing - SGS
the various ore types are the moisture, aluminium, iron and silica content. The silica content of the Cawse ore is mainly present as iron-rich quartz, whereas in Bulong and Murrin Murrin ore, it is incorporated into clays. In lateritic deposits, the nickel and cobalt do not usually occur in distinct minerals. Along with manganese, they are released
Laterite - Wikipedia
Laterite is a soil and rock type rich in iron and aluminium and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock.Tropical weathering (laterization) is a prolonged process of chemical weathering which produces ...
Microbial Treatment of Lateritic Ni-ore for Iron ...
06-02-2012· Lateritic nickel ore when subjected to treatment with anaerobic dissimilatory iron (III) reducing bacterial consortium show phase changes in iron minerals. Comparison of properties of thermally and microbially reduced lateritic ore vis a vis original ore show that changes in phases brought about by microbial reduction were different than those by thermal reduction.
Reduction of lateritic iron ore briquette using coal .
In this study, isothermal-temperature gradient method was used to separate iron and alumina in lateritic iron ore as an alternative technique. The lateritic iron ore was ground to obtain grain size of less than 200 mesh and agglomerated in the form of cylindrical briquette using a press machine. The iron oxide in the briquette was reduced by addition of coal so that all surface of the ...
Microbial Treatment of Lateritic Ni-ore for Iron ...
06-02-2012· ferent phases of iron present in lateritic nickel ore. Such conversion in lateritic nickel ore are helpful in better recovery of sorbed metal values like Ni and Co by subsequent bioleaching or acid leaching. Here properties of thermally and microbi-ally reduced lateritic nickel ore are compared vis -à-vis original ore.
direct reduction of lateritic iron ore process
Lateritic iron ore has not been used effectively due to excess content of ple metals. In this work, separation of aluminium from a high-aluminium lateritic iron ore was achieved by the process of 'direct reduction with sodium sulfate-magnetic separation', with a powdered direct reduced iron

lateritic iron ore | SpringerLink
lateritic iron ore; canga [A Brazilian term for a tough, well-consolidated, unstratified, iron-rich rock composed of varying amounts of fragments derived from itabirite, high-grade hematite, or other ferruginous material, and cemented by limonite (which may range from about 5% to more than 95%).It occurs as a near-surface or surficial deposit and blankets older rocks on or near the present or ...
Extraction of Nickel, Cobalt and Iron from Laterite .
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.

Mineral deposit - Rainwater | Britannica
Mineral deposit - Mineral deposit - Rainwater: Each of the deposit-forming processes discussed above involves the transport and deposition of ore minerals from solution. But solutions can also form deposits by dissolving and removing valueless material, leaving a residuum of less-soluble ore minerals. Deposits developed as residues from dissolution are called residual deposits.

Laterite nodules: A credible source of iron ore in .
There is, however, little information on the nature of iron production and the extent to which locally abundant and easily quarried lateritic iron may have been the ore source. For northeast Thailand archaeological sites, the presence of both iron slag and laterite iron nodules within and surrounding these sites has widely been assumed to represent localized smelting using locally sourced iron ...
