| titleOfInvention | A kind of raising selective method of lateritic nickel ore carbon thermal reduction |
| abstract | The invention discloses a kind of raising selective method of lateritic nickel ore carbon thermal reduction, with addition of sulfur-bearing auxiliary agent in lateritic nickel ore, use carbon thermal reduction sorting process to prepare ferro-nickel product.By the effect of sulfur-bearing auxiliary agent, under suitable carbon thermal reduction system, making nickel oxide in lateritic nickel ore be reduced into metallic nickel, and iron oxides part is reduced into metallic iron, remainder sulfur in auxiliary agent is combined and is converted into Iron sulfuret..Present invention achieves nickel and the selective reduction/sulfuration of ferrum in lateritic nickel ore carbothermic reduction process, can increase substantially and go back the grade of nickel in original product ferronickel, obtain the ferro-nickel product of high-quality, disclosure satisfy that stainless steel smelting ingredient requirement, the method has the features such as adaptability to raw material is strong, technological process simple, good product quality, processing cost are low, nickel recovering effect is good, and, low-cost processes efficient for following lateritic nickel ore provides new direction. |
