The invention relates to the field of smelting, and discloses an Indonesia's local laterite-nickel ore wet-process smelting method. The method comprises the following steps: 1) adding water into laterite-nickel ore and grinding the laterite-nickel ore into ore pulp; 2) adding hydrochloric acid and sodium chloride for leaching; 3) carrying out solid-liquid separation; 4) extracting and separating Ni < 2 + >, Fe < 2 + > and Cr < 3 + > in the liquid by using an extraction agent; 5) introducing ozone into the upper-layer extraction agent, carrying out solid-liquid separation, taking the precipitate as a main product, and circularly using the extraction agent; and 6) introducing the ozone into a lower-layer water solution, carrying out solid-liquid separation, and taking the precipitate as an auxiliary product after solid-liquid separation; and circularly using Na < + >, H < + > and Cl <-> in the lower-layer water solution. The method disclosed by the invention is innovated on the basis ofa traditional wet-process smelting process, and the local conditions are sufficiently taken into consideration, Indonesia's local specific natural resources are utilized, and most of the chemical agents are recycled, so that the production cost is greatly reduced, the whole process system tends to zero emission, the content of nickel in the product is high, and the recovery rate is high.
