A Smelting Process Of Ferronickel With Nickel Oxide Ore

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.

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.

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.
