This standard reminds users that they must have practical experience in formal laboratory work and does not cover all safety issues. Therefore, it is the responsibility of users to take appropriate safety and health measures to ensure compliance with national regulations. SN/T 2763 specifies the method for the determination of iron, nickel, silicon, aluminum, mg, calcium, titanium, manganese, copper and phosphorus in laterite nickel ore by wavelength dispersion X-ray fluorescence spectrometry. It is applicable to the determination of these elements in this mine. The scope is shown in Table 1. The documents that must be cited include GB/T 8170 and GB/T 16597. The former is the representation and determination of numerical revision rules and limit values. The latter is the general rule of X-ray fluorescence spectrometry for analytical methods of metallurgical products. Method Abstract: X-Rays Fluorescence intensity of the characteristic lines of the element to be measured in the measurement sample under the selected instrument measurement conditions
