Disclosed is a green method for hydrometallurgical production of a nickel-cobalt-manganese new energy raw material from laterite nickel ore. This method belongs to green technology and green process and mainly comprises such technologies and processes as ore blending, ore washing, beneficiation, pressure or oxygen pressure leaching, cyclic leaching and neutralization, counter-current washing, multistage iron-aluminum-chromium removal, multistage nickel-cobalt-manganese hydroxide synthesis, ion extraction, preparation of mixed solution of nickel-cobalt-manganese salt or independent solution of nickel, cobalt, and manganese salts, preparation of crystal of mixed nickel-cobalt-manganese salt or independent crystals of nickel, cobalt, and manganese salts, and preparation of a ternary precursor so as to achieve simultaneous and efficient extraction of nickel-cobalt-manganese, and effectively recover valuable metal elements such as chromium, iron, copper, zinc, and scandium, producing a nickel-cobalt-manganese raw material meeting the requirements of a high-nickel ternary battery, and manufacturing a ternary precursor material (also referred to as a ternary “key” or a ternary “core”) directly used in the manufacture of the ternary battery, and promote the transformation of laterite nickel ore from traditional smelting to the new energy raw material.
