CN103421922B - Method for producing ferronickel by ...

The invention provides a method for producing ferronickel by processing laterite nickel ore in Sulawesi, Indonesia through an RKEF technology. The method comprises the following steps: 1, prescreening a laterite ore raw material by a 50mm grizzly screen, crushing a part not passing through the screen by a jaw crusher to below 50mm, and mixing the obtained crushed material with a product ...

Lateritic nickel ore deposits - Wikipedia

Lateritic nickel ore deposits are surficial, ... FerroNickel process. A recent development in the extraction of nickel laterite ores is a particular grade of tropical deposits, typified by examples at Acoje in the Philippines, developed on ophiolite sequence ultramafics.

Production Process of Ferronickel - Miss Rifka

The choice of saprolite ore ensures that the ferronickel product is not excessively diluted by iron. Production process of ferronickel consists of four main steps. Drying: elimination of most or a substantial portion of free moisture content of the nickel ore

Making Ferronickel from Laterite Nickel Ore by Coal-Based ...

export of metal ores which included laterite nickel ore was prohibited from 2014. Therefore, this article mainly aimes to prepare ferronickel from low grade laterite nickel ore from Philippines by coal-based self-reduction process, which provides guidance for rational exploiting and utilizing of the low grade laterite nickel ore. 2.

WO2014133421A1 - Method for processing laterite nickel ore ...

The invention relates to the field of non-ferrous metallurgy and specifically to a method for processing laterite (oxidized nickel) ores with the direct production of ferronickel in the form of metal granules. The method comprises mixing the ore with a solid reducing agent and with fluxing additives, briquetting the resultant mixture, a reduction firing of the briquetted charge in tubular ...

PILOT PLANT PRODUCTION OF FERRONICKEL FROM …

objective of the smelting campaign was to illustrate the ferronickel from laterite process via the DC-arc furnace for the specific ore and achieve an average ferronickel alloy grade of 25% nickel. The calcined ore was processed in a DC-arc furnace, without operational problems, over a period of 32 hours.

Euronickel Industries

Euronickel owns and operates a nickel ore processing plant in Kavadarci, North Macedonia. The operation produces high quality ferronickel for use in the stainless steel producing industry.

FERRONICKEL PRODUCTION AND OPERATION

Production of ferro-nickel by pyrometallurgical process is still the most widely utilized method for the processing of nickel lateritic ores. The Ni-content of lateritic ore is normally low and in the range of 0.8 3 - %. The most important production route is the RKEF (rotary kiln -electric furnace) process [ 1, 2, 3].

SMELTING OF NICKEL OXIDE ORES TO PRODUCE FERRONICKEL ...

We claim 1. A process for producing ferronickel from nickel oxide ores which comprises: 2. The process of claim 1 wherein the nickel ore is chosen from the group consisting of laterites and serpentines and wherein said ore is calcined at a temperature sufficiently high to remove most of the chemically combined water contained in the ore prior to smelting.

FERRONICKEL PRODUCTION AND OPERATION

grade ferronickel or nickel pig iron (NP!) in stainless steel production is a relatively new trend to reduce the cost of high grade ferronickel. In this study, low grade lateritic nickel ores were processed by using carbothermal reduction to produce NP/. The used ore was from Turkey East Anatolian region.

About Euronickel Industries

The first nickel in the form of ferronickel produced was in 1982 from locally mined ores and the annual output was around 2,000 tonnes. The plant has operated under a number of different owners since then with its growth linked to the global nickel and energy prices. In 2017-2018 the plant went through a restructuring process.
