The refinery at Fort Saskatchewan was one of the first to utilise ammonia as a leaching reagent (Cooper and Mihaylov, 1997).The ammoniacal process involves pressure leaching of the nickel concentrate and matte with ammonia and oxygen in a series of autoclaves operating at 105–120 °C (Crundwell et al., 2011).This process aims to …
Through long weathering processes, Ni2+ replaces Mg2+ and Fe2+ in the lattice of corresponding silicates and ferric iron oxides, and is closely in conjunction with iron oxide and silicate minerals [8]. The concentration of nickel in an ore-body is very low, and typical nickel content in Chinese laterite ore is less than 1%.
The sulphidation of a nickeliferous lateritic ore was studied at temperatures between 450 and 1100 °C and for sulphur additions of 25–1000 kg of sulphur per tonne of ore. The experiments demonstrated that the nickel could be selectively sulphidized to form a nickel–iron sulphide. It was found that both the grade and the sulphidation degree ...
An alternative process of pre-roasting, phosphoric acid leaching followed by solvent extraction of a limonitic laterite ore was described in this work, with emphasis on the solvent extraction of Ni and Co from the phosphoric acid leaching solution by P204 and P507. First, the pH value of the leaching solution was adjusted using ammonia to reduce …

It should be added that segregation of laterite ores prior the flotation process has shown some improvement in upgrading nickel. The segregation process relies on the addition of calcium chloride or sodium chloride and carbon allowing the formation of nickel and iron chlorides at temperatures between 900 and 1150 °C. Iwasaki et al., (1961) and …
ore, including the banning of international exports of nickel ore by Indonesia. We remind members of the general guidelines when loading nickel ore cargoes, and share our …
This Guide defines the design parameters for such loading tolerance and provides the evaluation procedure and technical requirements for the optional notations LDCARE1 (Loading Care 1) and LDCARE2 (Loading Care 2). In addition, iron ore fines having a moisture content in excess of the Transportable Moisture Limit (TML) are only to be …
laterite nickel ore, the current development and utilization of technology has a lot of ... advantages, but in the process energy consumption and environmental load is significantly different, So it is necessary to make the necessary evaluation of different process routes, for reference and selection. Based on the above consideration, the ...
For both acid load cases, the nickel extraction was more sensitive to temperature increases whereas cobalt extraction became insensitive at lower acid load. At both 0.325 and 0.275 acid to ore ratios neither nickel nor cobalt extractions dropped below 90% even at the lowest temperature studied (240 °C).
LOADING NICKEL ORE This checklist should be used in conjunction with the ship operator's procedures for the loading of Nickel Ore and the IMSBC Code. If loading Nickel Ore in Philippines or Indonesia, you must notify North. Cargo Care Checklist: Nickel Ore (cont.) LOWER RISK CARGO Free particles Not flattened out No free water on surface
For these reasons, nickel ore has been described as 'the world's most dangerous cargo'. Nickel ore is a cargo that may liquefy if the Moisture Content (MC) …
The mineralogical phase identification of the ore samples was carried out using XRD (Rint-2000, Rigaku), and the results in Fig. 1 indicate that the major crystalline minerals in mixed oxide-sulfide nickel ore are pyrite (FeS 2), pyrrhotite (Fe 7 S 8), pentlandite ((Fe,Ni) 9 S 8), chalcopyrite (CuFeS 2) and quartz (SiO 2).It can be …
This guide aims to help masters, ship operators and other industry stakeholders understand the risks associated with the carriage of nickel ore cargoes. …
The LVS system NAC has purchased utilises laser scanning and RFID technologies, combined with software that creates 3D model images of trucks, to measure the exact volume of the material loaded in a truck or trailer bin. Joseph Limos of Nickel Asia commented, " We wanted to check the daily volume hauled from our contractors. The …
The nickel–cobalt alloy is a kind of permanent magnetic material and is widely used in the field of electronic remote control, atomic energy industry and ultrasonic technology [ 6, 7, 8 ]. Besides, in chemical industry, nickel and its alloys are usually used as catalysts for hydrogenation reactions. Fig. 1.1.
A copy of the Guide is attached hereto with the kind permission of INTERCARGO. It aims to help masters, ship operators and other industry stakeholders understand the risks associated with the carriage of nickel ore cargoes. Members are also referred to Club …
The extraction of nickel from the limonite ore initially correlates with the goethite reacted (Fig. 4), suggesting that the nickel is homogeneously distributed throughout the goethite and that maghemite contains only a minor amount of the total nickel present in this ore. Download : Download full-size image; Fig. 4.
The Goro Nickel Mine is one of the world's largest Nickel Laterite Mines. The project is owned by Vale (69%), a joint venture company composed of Sumic Nickel Netherlands, Sumitomo Metal Mining and Mitsui (21%) and the remaining 10% by three provinces within New Caledonia. The mine has a mineral reserve of 124 million tonnes, …
This paper describes the experimental findings of the extraction of nickel and cobalt by high pressure acid leaching (HPAL) of a refractory limonitic nickel laterite ore from the Gördes region of Manisa in Turkey. By optimizing the basic HPAL process parameters: leaching at 255 °C with 0.30 sulfuric acid to ore weight ratio with a particle ...
Best practice. The liquefaction of nickel ore during shipment can be attributed to two key factors, the moisture content of the cargo and the rolling and …

The sources of sulfur in the charge are carbon reductant and heavy fuel oil (1.8% S) and phosphorus, mainly carbon reductant and nickel ore. The smelting of ferronickel using lean nickel ores usually starts with roasting (calcining) of the ore mixture with limestone (~one third of the ore), anthracite (~1/10 of the ore amount), and recycled ...
