Abstract Facing the situation of nickel resource shortage and increasing nickel demand, it is an important task for the development of nickel industry to realize efficient utilization of low-grade nickel sulfide ore. In this work, the process of NaCl roasting-water leaching was proposed to simultaneously extract valuable metals from low-grade nickel concentrate. Based …
The mining grade of nickel sulfide ore is generally 0.3–2%. Copper-nickel bulk concentrate containing 4–8% nickel is usually selected by flotation. Some factories separate the bulk concentrate into nickel concentrate (containing about 10% nickel), copper concentrate, and pyrrhotite concentrate.
Nickel laterite ore with 7.88 wt% coal, 12 wt% calcium sulphate reduced at 1200 °C for 30 min, a ferronickel concentrate of Ni 8.08 wt%, and Fe 79.98 wt% was obtained at a nickel and iron ...

Nickel is upgraded by 17% and 36% for ore S and I, respectively. There is no change in the nickel grade of ore L using the Falcon, similarly to what was obtained using the magnetic separation. The XRD analysis of the light fraction of the Falcon concentrator for the ore S and I samples is presented in Fig. 4. It seems that both particle size ...
Ore is often processed near the mine site, but there is substantial regional and global trade in nickel laterite ores, and some trade in nickel sulfide concentrates. Laterite ores occur as surface deposits and are traditionally …
An Ore is a naturally occurring material in shape of rock which contains a metal compound. When extracted from the mine ore is typically crushed, ground and run through a beneficiation process to produce enriched ore called Concentrate .One of the most widely used ore beneficiation process is called froth flotation where the minerals are separated from each other.
Nickel sulfide ores contain nickel as pentlandite, which can be efficiently separated and concentrated using flotation methods. This conventional beneficiation process reduces costs and yields a high-grade nickel concentrate that can be smelted into a saleable product. [7] Laterite nickel ores are classified into limonite and saprolite.
also limited to concentrate the nickel. The mined ores (1–4% Ni) are processed to upgrade the metal content with 10–20% Ni in the concentrates. Thus, the preconcentration of nickel ores is an important unit operation to upgrade the nickel before commencing any extraction steps. Ni is mined from sulfide ores, Nickel ferrolaterite and serpentine.
McDonald et al.(McDonald and Li, 2020) studied the co-processing of low-grade nickel concentrate with high pyrite content and nickel laterite ore. The low-grade nickel concentrate with high pyrite content has sufficient acid-making capacity to leach nickel laterite ore without the need for additional acid.
The pressure oxidation of low-grade nickel sulfide concentrate with high iron sulfides content generates significant amounts of sulfuric acid that must be neutralized. This acid can be utilized to leach metal values from ores such as nickel laterites. The present study demonstrates the use of a low-grade nickel concentrate generated from Poseidon Nickel Mt …
The project is a brownfields extension 1–1.2 km north-northwest of the historical Carr Boyd Nickel Mine, which produced 202.1 kt of ore at an average grade of 1.43% Ni and 0.46% Cu, producing a 9.7% Ni concentrate.
Varies in colour. Exists in several types of variable particle size and moisture content, including some types containing clay-like ores. Has bulk density of 1,400 kg/m 3 to 1,800 kg/m 3.For Nickel concentrates, please see "Nickel concentrate" under the generic entry of "Mineral Concentrates".
The former constituents approximately 40 pct of the total ore reserves and account for half of the nickel production worldwide [1, 2]. Smelting followed by refining is the conventional technology to extract nickel from the sulfide ores as metallic nickel. ... A commercial nickel sulfide concentrate containing 18.8 mass pct Ni with ...
The acid-leaching tailings of laterite nickel ore are a hazardous waste generated by the laterite nickel ore industry [1], [2], [3].As global demand for nickel continues to rise and nickel sulfide resources decrease, the extraction of nickel resources from laterite nickel ores the main development trend of the global nickel industry in the coming years [4].
Nickel ores are processed to extract nickel and produce nickel-containing products, such as nickel matte, nickel pig iron, ferronickel, and nickel chemicals, which are used in …
The goal of the present work was to study the recovery of copper, nickel, and platinum group metals (PGMs) (Pt and Pd) from low-grade copper–nickel ore containing pyrrhotite, pentlandite, and chalcopyrite by column bioleaching followed by cyanidation. The ore sample contained the following: Ni—0.74%, Cu—0.23%, Fe—14.8%, Stotal—8.1%, and …
The former involves smelting of the ore or concentrate at high temperatures, while the latter involves leaching the ore or concentrate at relatively low temperatures, including ambient. These two broad processing paths may be broken down further into the following routes, as shown in Fig. 5, for copper and nickel ores:
From High-Pressure Acid Leaching (HPAL) for laterite ores to the pyrometallurgical route for sulphide ores and the hydrometallurgical approach for nickel laterites, the mining industry employs a wide range of methods to …
Finally, the nickel iron concentrate in the ore is magnetically separated. Fig. 3 shows the flow of the experimental process. The effects of the reducing agent dosage, reduction temperatures, reduction time, magnetic field strength, and CaO additions on the grades and recoveries of iron and nickel in laterite nickel ores were investigated. ...
