Effect of Co-Reduction Conditions of Nickel Laterite Ore and Red Mud on Ferronickel Particle Size Characteristics and Grindability of Carbothermic Reduction Products

The carbothermic co-reduction of nickel laterite ore and red mud realized the simultaneous reduction nickel, iron in ore, at high efficiency. Nickel were recovered form ferronickel. size characteristics ferronickel particles grindability products are essential for obtaining good technical indicators. influence conditions on particle relative was investigated by a test, analysis, determination. mean increased proportion coarse grew with improving temperature, increasing appropriately anthracite dosage, prolonging time. However, deteriorated when temperature improved time extended. negatively correlated to size. had most dominant effect grindability, followed dosage More nickel-bearing iron-bearing minerals reduced metallic state raising appropriate dosage. fine agglomerated merged into bulk grains prolonged results will provide theoretical guidance recovery mud.
