Abstract： In view of the geochemical characteristics of laterite nickel ore and the feature of containing mainly a high iron and low magnesium limonite in imported laterite nickel ore in China, a high precision and feasibility sampling and sample preparation method of bulk laterite nickel ore was established through a large amount of on-site experimental statistic data and reference to related sampling and preparation sample method of ISO, China, Japan. The proposed method was emplayed for sampling and sample preparation of a boat of laterite nickel imported from Indonesia. Through the determination of nickel,iron and water, it was found the sampling and preparation method precision(βs)and total precision (βspm) were all small and fit for the quality fluctuation law of goods, indicating a fine representativeness and reliability. The method is applicable to the sampling and sample preparation of imported nickel ore of China.
