Abstract

The invention relates to a method for quickly testing and analyzing the quality of sericite, which solves the problems that a microscope viewing method or chemical analysis method used in the prior art for testing the quality of sericite wastes time and labor and has low production efficiency. The method comprises the following steps: acquiring spectral information of the sericite sample to be tested by using a Fourier transform near-infrared spectroanalysis instrument, and analyzing the spectral information by using an optimal calibration model to obtain analysis result; the optimal calibration model is obtained by the following method: establishing a spectral library according to the spectral information of the sample, selecting representative spectral information to establish a calibration sample set, and gradually optimizing the quantitative analysis model of the spectral information of the sample by using a cross validation method according to the calibration sample set until obtaining the optimal calibration model. The method is suitable for quickly testing the purity analysis on the sericite in the green ore exploration and the tailing recycle.

Description

technical field [0001] The invention relates to a method for quickly detecting and analyzing the quality of sericite. Background technique [0002] my country is rich in sericite resources and widely distributed. There are large sericite mines in Shaanxi, Anhui, Fujian, Hubei, Heilongjiang, Inner Mongolia, Shandong and other provinces. This resource advantage provides the necessary conditions for the development of sericite, which is of great significance to the research of sericite. Increasing the output and quality of sericite, reducing production costs, protecting the surrounding environment of mines, and improving the comprehensive utilization of mine resources are the main issues of sustainable development of mines. The development of sericite is mainly through the mining of sericite ore and the recovery of sericite from tailings. The quality of mining and recovery of sericite directly affects the application and price of sericite, especially in recent years. The qual...
