| titleOfInvention | Method for gathering nickel and iron from laterite-nickel ores |
| abstract | The invention discloses a method for gathering nickel and iron from laterite-nickel ores. The method for gathering nickel and iron from laterite-nickel ores is characterized by comprising the following steps of 1, drying laterite-nickel ores, crushing the dried laterite-nickel ores into laterite-nickel ore powder having particle sizes of 2 to 10 millimeters, and crushing coal into coal powder having particle sizes of 2 to 10 millimeters, 2, uniformly mixing the laterite-nickel ore powder and the coal powder according to a weight part ratio of (5 to 50): 100, 3, putting the mixture into a reduction heating furnace, heating to a temperature of 1050 to 1400 DEG C, keeping for 30 to 90 minutes, and cooling, 4, grinding when the mixture is cooled to normal temperature, wherein grinded products have particle sizes less than 0.1 millimeters, 5, carrying out magnetic separation, removing tailings obtained by the magnetic separation, feeding back middlings obtained by the magnetic separation for re-reduction, controlling a grade of nickel in concentrates obtained by the magnetic separation in a range of 4 to 8% so that recovery rates of nickel and cobalt are greater than 90%, and feeding the concentrates as raw materials into an electric furnace nickel smelting system or carrying out wet leaching of the concentrates, and 6, carrying out comprehensive recovery of nickel and cobalt. The method for gathering nickel and iron from laterite-nickel ores can realize a laterite-nickel ore enrichment ratio of 4 to 8% in a non-bonded raw material state, remove a part of tailings, and improve a recovery rate through feeding back of middlings obtained by magnetic separation. |
