The invention provides a method for producing ferronickel by adopting a rotary kiln direct reduction-RKEF (Rotary Kiln-Electric Furnace) combination method. The method comprises the following steps: drying a laterite nickel ore for later use; crushing and screening an appropriate amount of the dried laterite nickel ore, and then mixing the screened laterite nickel ore with a carbonaceous ...

From the rotary kilns, the ore is moved into the electric reduction furnaces, where approximately 50% of the sulphur in the iron/nickel alloy is removed. The remaining sulphur is removed from the liquid metal in the oxygen converters, and the iron/nickel alloy is then cast into ferronickel granules.

Ferronickel. The rotary kiln and electric furnace process has long been the most commonly employed method of recovering nickel from saprolitic laterite ores. Production improvements have been achieved over the years by the adoption of “shielded arc” smelting and the installation of water-cooled copper cooling elements in the furnace sidewalls.

Ferronickel smelting of lateritic ores is generally performed by using fossil fuels (coal, oil, natural gas, etc.) as a reductant in a rotary kiln. Nickel and cobalt are firstly reduced because iron has greater affinity to oxygen. The product is charged to converter for refining after discarding the slag

In the production of ferroalloys, nickel-iron is one of the more refractory metals. There are three main methods for its capacity: 1. smelting by blast furnace method; 2. direct reduction smelting of rotary kiln; 3. rotary kiln-mineral furnace method; The most used one is the rotary kiln-mineral furnace method.

Mar 10, 2021 Two-thirds of the global nickel output can be attributed to the rotary kiln-electric furnace process. Due to the high contents of MgO and SiO 2 in laterite, a high temperature (∼1600 C) and corresponding energy (approximately 14 GJ/t-ferronickel) are required during the electric furnace smelting. This work verifies the feasibility of decreasing the smelting temperature by controlling the ...
