Ore and nickel concentrate into nickel matte, nickel ox-ide, ferronickel, nickel cobalt intermediates and other nickel and non-nickel by-products. Around 36 of the global nickel production originates from sulphidic ore the remaining 64 from lateritic oxidic ore.Apr 15, 2020 Ferronickel concentrate with Ni of 16.16 , Fe of 73.67 , and nickel About 70 of the world’s nickel production comes from nickel sulfide and 30 from nickel oxide. There are than 60 known nickel minerals, There are abundant nickel oxide ore resources in the Yuanjiang, Mojiang, and Mangshi areas of.

CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda) 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.

Due to limited reserves of nickel sulphide, which has been dominating the world's nickel production and the increasing of nickel metal demand, further development related to the production of nickel from nickel oxide or lateritic ores should have been a new concern. Selective reduction of saprolitic laterite ore types have been carried out with nickel and iron content in the ore, respectively.

Blast furnace ferronickel production process mainly is dry sieving ore (bulk crushing) - ingredients, sintering sinter and coke into blast furnace smelting flux and block - nickel iron ingot and slag water quenching - producing nickel ingot iron and slag. Domestic nickel oxide ore resources are poor, to rely on imports, imports of complex.

Nickel slags can be produced through ferronickel preparation by the pyrometallurgical processing of laterite nickel ores however, such techniques are underutilized at present, and serious environmental problems arise from the stockpiling of such nickel ores. In this study, a modification to the process of ferronickel preparation by the direct reduction of carbon bases in laterite nickel ores.

Abstract 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.

A second charge consisting of calcined nickel ore mixed with about 24 percent of the coke stoichiometrically required to reduce nickel oxide (NiO) and iron oxide (Fe 2 O 3) to metal was added to the furnace and smelted. After smelting was complete, a ferronickel product was tapped from the furnace leaving a nickel-rich slag within the furnace.

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].

Ferronickel is an ingredient used in the production of nickel cast iron and in the production of stainless steel. The conventional electrothermal ferronickel process as practiced in New Caledonia involves a stage of preheating the lateritic ore for removal of volatile constituents such as free water and water or recrystallization.
