ferrovanadium, nickel carbonate, nickel laterite, iron ore reduction, and spodumene lithium production. In this paper the direct reduction of iron ore to sponge iron is used as an example. The model incorporates a large number of variables covering, amongst others feed properties and rates, combustion options, kiln
Modelling and optimization of a rotary kiln direct reduction process 55 Figure 3. Kiln temperature distribution for the base case The feed material bed enters the kiln at ambient temperature and rapidly heats up due to the hot gas in the freeboard.
ously fed to a rotary kiln in which the stages of drying water, dehydration of serpentine, reduction and partial melting of siliceous ores are passed. Particles of ferronickel alloys, obtained as a result of reduction of Fe and Ni oxides by anthracite, grow during travel countercurrent to the ow of hot gas.
A process is disclosed for prereducing metallic oxide and sulfide ores to a lower state of oxidation without passing through a liquid phase, at an accelerated rate. The ore particles are preheated to 1,800 or above. An unreformed hydrocarbon fuel such as natural gas CH4 substantially free of any oxidizing agents is passed into a bed of such preheated ore particles to pyrolytically decompose ...
Aiming for preparing NPI from nickeliferous laterite ore, a pilot-plant scale test of coal-based rotary kiln direct reduction of laterite ore was performed and reported in this study.

rotary kilns. Pellets, or lump-ore, mixed with coal areis charged into the rotary kilns2 and heated by coal burners to produce DRI. To avoid the significant formation of the kiln rings, their operating temperatures must be maintained in a range from 1,000 to 1,1003. As a result, the processes require about 12 hours of reduction
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.
Preliminary Reduction. Once ore has been dried, it is processed in a large-scale rotary kiln to remove chemically bound moisture, as well as the oxide component of the ore. This step is often referred to as pre-reduction. Reduction amp Smelting. Nickel is further reduced and smelted in an electric furnace.
to the rotary kiln. The ores were preheated and calcined in the kiln before transferred to the ELKEM AS Engineering Division, Norway. smelting furnace. The reductants, coarse crushed low volatile coals 30 mm , were added to the smelting furnace where all the reduction of iron and nickel oxides took place. The furnace
