Introduction

Since there are many elements involved in the detection process of phosphate ore and phosphate concentrate, the applicable scope and applicable methods of the elements are different. for To facilitate the detection of different elements in phosphate rock and phosphate concentrate, GB/T 1871 is divided into 5 parts. ---GB/T 1871.1 Determination of phosphorus pentoxide content in phosphate rock and phosphate concentrate—Quinoline phosphomolybdate gravimetric and volumetric methods. target The main method is to measure the content of phosphorus pentoxide in phosphate rock and phosphate concentrate, using quinoline phosphomolybdate gravimetric method and volumetric method. ---GB/T 1871.2 Volumetric and spectrophotometric methods for the determination of iron oxide content in phosphate rock and phosphate concentrate. The purpose is to measure The iron oxide content in phosphate rock and phosphate concentrate was determined by volumetric and spectrophotometric methods. ---GB/T 1871.3 Volumetric method and spectrophotometric method for determination of alumina content in phosphate rock and phosphate concentrate. The purpose is to measure The alumina content in phosphate rock and phosphate concentrate was determined by volumetric and spectrophotometric methods. ---GB/T 1871.4 Volumetric method for determination of calcium oxide content in phosphate rock and phosphate concentrate. The purpose is to measure phosphate rock and phosphorus concentrate The content of calcium oxide in the ore was measured by volumetric method. ---GB/T 1871.5 Determination of Magnesium Oxide Content in Phosphate Rocks and Phosphate Concentrates by Flame Atomic Absorption Spectrometry, Volumetric Method and Inductance Coupled Plasma Emission Spectroscopy. The purpose is to measure the magnesium oxide content in phosphate rock and phosphate concentrate, using flame atomic absorption Spectroscopy, volumetric and inductively coupled plasma emission spectroscopy. Determination of magnesium oxide content in phosphate rock and phosphate concentrate flame atomic absorption spectrometry, volumetric methods and Inductively Coupled Plasma Emission Spectroscopy Caution—The personnel using this section should have practical experience in formal laboratory work. This section does not address all possible security concerns question. It is the user's responsibility to take appropriate safety and health measures, and to ensure compliance with relevant national regulations and conditions.
