The hydrometallurgical process for smelting to recover nickel and cobalt from a nickel laterite ore by a High Pressure Acid Leach comprising an ore treatment step, a leaching step, a solid-liquid separation step, a neutralization step, a zinc removal step, a sulfurization step, and a final neutralization step, which process prevents wear of equipment, caused by an ore slurry, and also reduces amount of a final neutralization residue, as well as separates and recovers impurity components so as to contribute to resource recycling. It is characterized by having at least one step selected from the following steps (A) to (C). (A) separation and recovery, by a physical separation method, of particles comprising at least one kind selected from a silica mineral, chromite or a magnesium silicate ore in ore slurry produced from the above-described ore treatment step. (B) separation and recovery, by a physical separation method, of hematite particles in leaching residue slurry produced from the above-described solid-liquid separation step. (C) step for subjecting a neutralization precipitate slurry produced from the above-described neutralization step to the final neutralization treatment separately from the leaching residue produced from the above-described solid-liquid separation step.
