Detection range: metal elements in the ore qualitative and quantitative analysis of the form of compounds, trace elements in minerals, ultra trace element analysis, non-ferrous metals, rare earth ore, precious metal ore composition analysis and so on.
Performance testing:
The hardness, mineral elements, rock density, chloride ion content, metal elements, vapor pressure, organic matter content, moisture, frost resistance, compressive strength, light substance content, refractive index, color fastness, particle size distribution, mineral morphology analysis, wear test, fineness, whiteness, no matter, refractive index, including clay content, porosity, water absorption, moisture content, alkaline activity test, abrasion resistance, transparency, acid resistance, alkali content, gloss
Element content detection:
Detection method:
Weight method: long term for the determination of the total amount of rare earth. The method is clean and accurate, and it is recommended as an accurate analysis and standard analysis method. In addition, the determination of the constant moisture and burning loss of rare earth is also used in the weight method.
Volumetric analysis method for the determination of the total amount of rare earth, cerium content and the raw materials used in the smelting process (hydrochloric acid, sulfuric acid, etc.). Including the complex titration method (EDTA titration total amount of rare earth), redox titration method (ammonium ferric sulfate method of cerium content), acid and alkali titration method (hydrochloric acid, sulfuric acid and other concentration analysis).
Spectrophotometric Determination of trace impurities in rare earth, such as silicon, phosphorus, chloride, sulfate, etc..
Atomic absorption spectrometry analysis: for the analysis of rare earth products, the determination of non rare earth impurities is often used, because most of the elements are quantitative to be dissociated into atomic vapor, so the atomic absorption spectrometry can be used for quantitative determination.
