Embodiment

[0025] Embodiment: The steps of the method for determining the content of components in fluorite by using the X fluorescent powder pressing method are as follows.

[0026] 1. Use X-ray fluorescence spectrometer to create an analysis method: select the analysis parameters of the eight elements of calcium, fluorine, silicon, phosphorus, sulfur, iron, potassium and sodium, crystals, detectors, peak 2θ angles and measurement time, etc. as shown in Table 3.

[0027]

[0028] 2. Preparation of standard sample compression: select a suitable standard fluorite sample, the typical component content is shown in Table 4; at the same time, select a representative self-selected fluorite sample with a certain content gradient and use chemical method and ICP-OES method As a supplement after analysis and determination, the contents of some components are shown in Table 5 to obtain fluorite standard samples. Accurately weigh the fluorite standard sample and binder according to the ratio of ...

Abstract

The invention discloses a method of measuring component contents in fluorite by applying an X fluorescence powder tablet pressing method. The method comprises the following steps of: (1) pressing a fluorite standard sample and an adhesive into a group of standard sample pressed tablets with proper CaF2 gradient contents; (2) preparing a sample to be tested and the adhesive into a sample pressed tablet to be tested; (3) analyzing the standard sample pressed tablet by using an X fluorescence spectrometer and acquiring a linear regression analysis curve by enhancing absorption and deducting spectral line overlapping interference after the analysis is finished, then selecting and using the working curve to measure the sample pressed tablet to be tested, and calculating the contents of various components of the fluorite according to correspondence of analyzed spectral line intensity and concentration; and (4) pressing the standard sample pressed tablet and the sample pressed tablet to be tested by uniformly mixing and grinding the fluorite standard sample as well as the fluorite sample to be tested and the adhesive respectively, sieving through a 300-mesh screen and finally pressing into tablets in a tablet press. The method is quick and accurate, the check cost is reduced, and the check efficiency is greatly increased.

Description

technical field [0001] The invention relates to a method for determining the content of components in fluorite, in particular to a method for determining the content of components in fluorite by using an X fluorescent powder pressing method. Background technique [0002] Fluorspar, also known as fluorspar, is mainly used in the steel industry to make slag in blast furnace or converter steelmaking. Fluorspar is a typical silicate mineral, and its main components are calcium fluoride, silicon dioxide and a small amount of carbon. salts, phosphates. The important basis for evaluating its quality index is the content of calcium fluoride, silicon dioxide and other components. At present, chemical methods and fluorescence methods are generally used to determine the components in fluorite. The chemical method analysis is cumbersome, and the determination of calcium fluoride content requires two filtrations, which takes about six hours. Fluorescence method mostly adopts melting sa...
