A SMELTING PROCESS OF FERRONICKEL WITH
1 A metallurgical method of ferronickel production by blastfurnace smelting nickel oxide ore without crystal water, wherein the said method of blast furnace smelting mainly comprising the following steps: Crushing and sieving raw ores, separating raw ore block in particulate diameter of 1060 mm and ore powder in grain diameter smaller than 10 mm, and mixing the feed of ore powder in grain Mintek has been working on the production of unrefined ferronickel from nickelcontaining laterite in DCarc furnaces since 1993 In this process, lateritic material is fed, together with a carbonaceous reducing agent, to the central region of the molten bath of a cylindrical DCarc furnace This feed material is preferably pretreated, ie Production of ferronickel from nickel laterites in a DC Nickel oxide ore is usually called laterite, which represents 61% nickel ore on earth and 40% of world is in the form of laterite Laterite ore normally classifide into two groups: Feed material for ferronickel production is predominantly saprolite, rather than limonite This is because the iron content of the saprolite ore about 15% Fe, is Production Process of Ferronickel Miss Rifka
FERRONICKEL PRODUCTION AND OPERATION
The Nicontent of lateritic ore is normally low and in the range of 08 3 % The most important production route is the RKEF (rotary kiln electric furnace) process [ 1, 2, 3] For this route lateritic ore is screened, crushed and blended to produce a consistent process plant feed with defined ratios of iron and nickel as well as Si02 and MgOThe exploitation of nickel ore for the production of ferronickel is from the Koniambo massif The saprolite deposit contains 756 million tonnes of measured and indicated resources grading 247% of nickel and 83 million tonnes of inferred resources grading 25% The Koniambo orebody extends over 20 kilometers long and 5 kilometers wideKoniambo Nickel SAS – SMSPCiteSeerX Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Laterites and other oxidized nickel ores constitute a very important part of worldwide 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 PILOT PLANT PRODUCTION OF FERRONICKEL FROM
