The method of producing ferronickel at low temperature (1250–1400°C) has been applied since the 1950s at Nippon Yakin Kogyo, Oheyama Works, Japan. Limestone was used as an additive to adjust the slag composition for lowering the slag melting point. The ferronickel product was recovered by means of a magnetic separator

OneStep Extraction of Nickel from Nickel Sulfide

The conventional nickel smelting and refining is the dominant strategy for nickel production from the sulfide nickel ores. The main disadvantages are the significant amount of SO 2 emissions during smelting and complex refining processes. In this paper, the authors investigated a solidstate nickel extraction method that recovered nickel

Preparation of Ferronickel from Nickel Laterite Ore via

The rotary kilnelectric furnace (RKEF) process is the main method for producing ferronickel from nickel laterite ore . However, this process is energy intensive as it involves several high temperature steps. Therefore, a novel process is proposed to directly produce ferronickel from nickel laterite ore by semimolten reduction,which is

Effect of CoReduction Conditions of Nickel Laterite Ore

The carbothermic coreduction of nickel laterite ore and red mud realized the simultaneous reduction of nickel, iron in laterite ore, and iron in red mud at high efficiency. Nickel and iron in nickel laterite ore and iron in red mud were recovered in the form of ferronickel. The size characteristics of ferronickel particles and grindability of

produce ferronickel products. Hydrometallurgical processes based on ammonia or sulfuric acid leach are also used. Ammonia leach is usually applied to the ore after the reduction roast step. Sulfidic Ore Processing Flash smelting is the most common process in modern technology, but electric smelting is used for more complex raw materials when

Ferronickel Preparation from Nickeliferous Laterite by

In the recent years, ferronickel has been used as a substitute for electrolytic nickel for alleviating the cost of stainless steel production. Rotary kilnelectric furnace (RKEF) smelting is currently the worldwide mainstreaming process for ferronickel production from nickeliferous laterite ore, in spite of the high power consumption.

Ferronickel an overview ScienceDirect Topics

Ferronickel is usually cast on conveyor machines in ingots of 25 to 35 kg weight. The specific energy consumption for processing 1 ton of dry lean nickel ore (1% Ni) is 810 kWh or 78 200 kWh per 1 ton of nickel. The use of richer ores (2.5% to 3.0% Ni) allows the decrease of specific energy consumption at least twofold ( Novikov et al., 2005 ).
