| titleOfInvention | A kind of method for preparing iron phosphate dihydrate and ternary positive electrode material from laterite nickel ore |
| abstract | The invention relates to the technical field of recycling and utilization of nickel ore materials, in particular to a method for preparing iron phosphate dihydrate and a ternary positive electrode material from laterite nickel ore. The method for preparing iron phosphate dihydrate and ternary positive electrode material from laterite nickel ore includes: mixing laterite nickel ore and nitric acid solution for acid leaching treatment, solid-liquid separation to obtain leaching slag and leaching solution; mixing the leaching solution and phosphoric acid solution under heating conditions , after solid-liquid separation, iron phosphate dihydrate and first-level filtrate are obtained; iron element, chromium element, aluminum element, calcium element, magnesium element are removed from the first-level filtrate, and nickel-cobalt-manganese mixed solution is obtained after solid-liquid separation; The nickel-cobalt-manganese mixed solution is mixed with soluble nickel salt, cobalt salt, manganese salt and lithium salt, and then cracked and sintered to obtain a ternary positive electrode material. The method can efficiently realize the separation of nickel and cobalt from iron, efficiently recycle iron in laterite nickel ore, greatly reduce the waste of iron resources, and realize high-value comprehensive utilization of laterite nickel ore. |
