May 01, 1987 Direct reduction of garnierits ore for production of ferro-nickel with a rotary kiln at Nippon Yakin Kogyo Co., Ltd., Oheyama Works. Int. J. Miner. Process., 19: 173-187. During World War II, the Nippon Yakin Kogyo Co., Ltd. produced sponge iron with the Krupp- Renn process at the OheyAmA Works from laterite ore mined at the nearby OheyRma Mine.
About this site
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

Modelling and optimization of a rotary kiln direct reduction process by H.P. Kritzinger* and T.C. Kingsley* Synopsis Rotary kilns are used for a variety of mineral processing operations. Hatch
IBU-tec The Rotary Kiln Experts for Trials and Production
Rotary kilns (sometimes called calciners or rotary furnaces) are used for thermal treatment processes such as calcination, sintering, pyrolysis and firing, as well as for oxidation and reduction.These treatments can be applied to powders, granulates, suspensions and green bodies.A rotary kiln consists of a cylindrical, rotating body mounted between stationary material feed and outlet housings.
Laterite Nickel Ore Roasting Kiln haagdeko.de
Direct reduction of garnierite ore for production of ferro-nickel with a rotary kiln at nippon yakin kogyo coltdoheyama works controlling scale composition during acid pressure leaching of laterite and garnierite ore syntectonic mobility of supergene nickel.
Direct Reduction of Limonitic Laterite Nickel Ore with
The increasing demand for stainless steel and the scarcity of sulfide nickel ore affect the increase of laterite nickel ore processing. One of the processes that has been proven can be applied to process laterite nickel ore is direct reduction. In the direct reduction, the reduction atmosphere was adjusted by controlling the volume of CO and CO2 from carbon source materials, such as coal
