Smelting Prereduced Nickel Concentrate in an Electric-Arc Furnace Materials Used for Smelting Tests in the Electric-Arc Furnaces. The nickel-bearing concentrate used during this investigation was from ore mined by FENI in Kavadarci, Yugoslavia.
Jun 24, 2021 Indonesia is considering a plan to restrict construction of smelters producing nickel pig iron or ferronickel in order to optimise use of its limited nickel ore reserves for higher-value products.Laterites and other oxidized nickel ores constitute a very important part of world-wide nickel reserves. The development of nickel oxide ore smelting has drawn heavily on iron and steel metallurgy. In ferronickel production, the nickel oxide and part of the iron oxide are reduced to metal in an electric furnace to form immiscible layers of slag and metal. The crude ferronickel is tapped from the furnace and refined to saleable ferronickel.

As a responsible producer, we are committed to continuously improving the performance of our operations for the benefit of all stakeholders.
High Temperature Processing Symposium 2014 Swinburne University of Technology 29 (a) (b) Figure 1 (a) Flowsheet of ferronickel production from nickel laterite, (b) schematic of electric furnace for smelting of laterite The oxides in the feed are NiO, FeO, SiO.Nov 01, 2016 The process of using pre-concentrate nickel-iron ore to make low ferronickel has a higher recovery of Ni of 93.38 than normal smelting process recovery of 90 . And the impurities of P and S are low in the product. It can be used to produce 200 stainless steel.
Forth. This study is related to the production of ferronickel alloys. Especially, melting behavior of nickel ores was fo-cused on when extracting ferronickel alloys. As an extracting method,1,2) ferronickel alloys are pro-duced from siliceous nickel ores by means of a rotary kiln modifying Krupp–Renn process. Siliceous nickel ore is so.The exploitation of nickel ore for the production of ferronickel is from the Koniambo massif. The saprolite deposit contains 75.6 million tonnes of measured and indicated resources grading 2.47 of nickel and 83 million tonnes of inferred resources grading 2.5 . The Koniambo orebody extends over 20 kilometers long and 5 kilometers wide.
In less than 18 months since its listing, Silkroad Nickel has developed downstream smelting and processing business opportunities – transforming from its primary nickel mining operations into a vertically-integrated nickel producer of Lateritic Nickel Ore, Nickel Pig Iron (“NPI”) and Ferronickel (“FeNi”) products for the growing.Jul 06, 2020 The purpose of MHP agglomeration is the hydro-pyro integration, by which the nickel concentrate (MHP) can be used in ferronickel smelters through pellets with acceptable granulometry to be processed in furnaces. Complete processing route, from lateritic ore to nickel alloy, has advantages obtaining MHP as a nickel intermediate product.
Hydro-Pyro Integration in the processing of Nickel Laterites . Authors Anne Oxley a, b and Dr Nic Barcza c . benefits especially as nickel laterite ore grades diminish. The nickel production followed by either refining to produce a ferronickel product or converting to a low iron-containing matte.A brief description of the cutting-edge technologies we use at Koniambo Nickel’s industrial complex, with an ore processing flowchart, from extraction to export. Ferronickel production begins well before ore is taken from the ground. It all starts with drilling campaigns and mine modelling.
Nickel processing - Nickel processing - Extraction and refining The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel.Sep 29, 2020 Ferronickel alloy is one of the resources for austenitic stainless steel manufacturing. During the past 20 years, the consumption of laterite nickel ore has been increasing, because laterite is used as raw material for ferronickel alloy smelting.[1,2] The laterite nickel ore can not be concentrated like sulphide, and it must be smelted directly Crude ferronickel alloy can be produced by the.
Ferronickel. Euronickel produces high quality, low carbon ferronickel granules comprising approximately 20 nickel and 80 iron that are primarily used in the production of stainless steel. Our ferronickel is shipped in bulk or in 1.8t bags from North Macedonia to major steel makers in Europe and internationally. The physical characteristics of.Jun 23, 2021 Indonesia's government is discussing with a parliament committee a plan to limit construction of smelters producing nickel pig iron or ferronickel in order to optimise nickel ore.
ANTAM conducts open pit mining method with a selective mining to produce high grade and low grade nickel ore. Nickel ore is used for ore feed for Pomalaa ferronickel plant as well as being sold to domestic market. ANTAM sun dries its mined nickel ore before being screened to be crushed into desired size. Ore is transported using belt conveyor to the stockpile area before the end of being used in ferronickel processing.Jun 24, 2021 Indonesia's government is discussing with a parliament committee a plan to limit construction of smelters producing nickel pig iron or ferronickel in order to optimise nickel ore.
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.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].
