Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] A method for measuring mineral reflectance and mineral phase composition, including sample preparation→collecting images→measurement of reflectance→measurement of mineral composition; it is characterized in that the collected images are composed of images including mineral phase microscopes, video cameras, image acquisition cards and computers The acquisition system is carried out. Firstly, the light sheet of the mineral to be tested is observed on the mineral phase microscope, and the picture of the mineral is obtained by the camera and the image acquisition card and input into the computer; The k value under the irradiation intensity is calibrated; finally, the computer calculates the reflectance and the content of the mineral composition, and the computer performs the following steps:

[0023] 1) Image preprocessing: using smoothing t...

Abstract

This invention supplies a method of measuring mineral reflectivity and mine phase composition. First put mineral polished section on reflected light microscope for observation, by camera and image collecting card to obtain mineral picture to input computer;then utilize given reflectivity core sample to carry out k value standardization of image acquisition system at certain intensity of irradiance; finally by computer calculating reflectivity and mineral composition content, calculator execute as follows step;image preprocessing;abstract measuring point's R, G, B pixel value; Calculate reflectivity base on this invention supplied model, and count pixel point size in whole picture belong to mineral reflectivity interval; thereby calculate reflectivity and mineral composition content. This invention not only accuracy, quickly, large depress detecting personnel labor intensity and working hours;Furthermore has no need of external equipment, just need fixing corresponding software, to realize mineral image reflectivity's two-dimension visualization.

Description

technical field [0001] The invention relates to a method for measuring mineral phase and petrographic reflectance of sinter, pellets and blast furnace slag in the field of metallurgy, in particular to a method for measuring the reflectance of minerals under a reflective (mineral phase) microscope, thereby accurately and quickly obtaining ore method of composition. Background technique [0002] At present, the main methods for measuring the reflectance of mineral phases and lithofacies such as sinter, pellets and blast furnace slag in the field of metallurgy are visual inspection and instrument measurement. Visual methods mainly include side-by-side comparison method and visual photometry; instrument measurement methods include colorimetric eyepiece method and photoelectric photometry. The visual method relies too much on the subjective judgment of the observer, and the conclusions and data drawn by observers with different eyesight and experience are different, which can ea...
