This invention relates to application of laterite nickel ore in producing sinter and a production method for the sinter utilizing the nickel laterite ore, and also provides the sinter produced by the method. In the technical scheme provided by the invention, high, medium, low-grade laterite nickel ore are used to partially or completely substitute for ordinary iron ore for sinter production, reduces the production cost of the sinter, improves the application range of the laterite nickel ore, and sufficiently utilizes nickel, chromium, magnesium, manganese and other useful elements in the lateritic nickel ore. According to the invention, the sinter provided can be used as a main raw material for producing 200 and 300-series stainless steel and high-strength alloy steel; the addition of trace nickel, chromium and other elements improves the performance of common carbon steel, nickel recovery rate to 85% and iron recovery to more than 80%; and the production process is simple and has good economic benefits and a
