Problems solved by technology

However, the mercury used in the determination process cannot be eliminated, which will cause certain pollution to the environment
The instrument analysis method has the advantages of fast detection speed and the ability to eliminate the influence of human subjective factors. However, how to reduce the interference of complex matrix as much as possible and improve the accuracy of instrument detection involves sample pretreatment and optimization of instrument analysis software, which still needs to be further improved.

Abstract

The invention relates to a method for detecting total iron content of iron ore based on spectral data. The method comprises the following steps that spectral data of an iron ore sample to be detectedis acquired, and the spectral data comprises M spectral characteristics; the spectral data is inputted into an iron ore classification model to obtain the iron ore type of the iron ore sample to be detected; and according to the obtained iron ore type, the spectral data is inputted into an iron ore total iron content detection model of the corresponding iron ore type to obtain the iron ore total iron content corresponding to the spectral data. The method for detecting the total iron content of the iron ore based on spectral data has the advantages of high efficiency, low cost and high precision.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a method for detecting total iron content of iron ore based on spectral data. Background technique [0002] Hematite and magnetite are the main types of iron ore, and the iron content in iron ore determines the grade and quality of iron ore. The grade and quality of iron ore are related to the cost and economic benefits of mining ore. Choosing an accurate and simple method for determining the total iron content of iron ore has an important guiding role in mining iron ore and obtaining greater economic benefits. There are mainly chemical analysis methods and instrumental analysis methods for the determination of total iron content in iron ore. The most commonly used chemical analysis method is the classic potassium dichromate titration method, which has high sensitivity and strong applicability, and can accurately and quantitatively observe the size and change of d...
