Problems solved by technology

Since the content of elements is not equal to the content of minerals, the symbiosis of multiple minerals containing the same element is common, and the analysis of mineral components in the laboratory has poor timeliness and high cost, and cannot be used for real-time monitoring in production

Abstract

The invention discloses an on-line analysis method for mineral in ore pulp. The on-line analysis method comprises the following steps: irradiating to-be-analyzed ore pulp with an X-ray emitted from an X-ray tube, and arranging a detector at each of two sides of the ore pulp to perform X-ray fluorescence detection and diffraction detection; performing quantitative analysis on a mineral constituent in the ore pulp according to an X-ray fluorescence detection result and a qualitative standard diffraction diagram gallery; combining a result of quantitative analysis on the mineral constituent with a diffraction detection result, and by analyzing a diffraction peak of water, establishing a correction equation between a diffraction peak and concentration to finally realize on-line analysis on the ore pulp. By adopting the method disclosed by the invention, the on-line analysis on the mineral constituent in the ore pulp can be realized, and mineral constituent information is provided for a flotation dressing process in real time; meanwhile, problems of traditional technologies of the on-line analysis on the ore pulp, in-situ calibration and the like are also solved, and the on-line analysis method is convenient for popularization and application.

Description

technical field [0001] The invention relates to the technical field of pulp analysis, in particular to an online analysis method for pulp minerals. Background technique [0002] Mineral beneficiation is a process of separating minerals from gangues by using different processes according to the physical and chemical properties of different minerals in the ore. [0003] At present, current-carrying X-ray fluorescence grade analyzers are widely used at home and abroad to realize the online detection of metal elements in the flotation process, guide production and process control; very few mines conduct offline mineral component analysis in the laboratory. Since the content of elements is not equal to the content of minerals, the symbiosis of multiple minerals containing the same element is common, and the timeliness and high cost of laboratory mineral composition analysis are poor and cannot be used for real-time monitoring in production. Contents of the invention [0004] T...
