Problems solved by technology
[0002] At present, most of the process mineralogy detection technology stays in the detection category, and the accuracy and precision of the detection are not clear, which leads to the disconnection between the detection results and the experimental research. Therefore, in order to improve the comprehensive application level of process mineralogy detection and experimental research, to form a guiding relationship between them, and to avoid the disadvantages of the transformation of later research results into first-line production, after repeated demonstrations, this technology is specially summarized.

Embodiment Construction
[0017] The present invention will be further described below in conjunction with specific examples.
[0018] A specific implementation method of a method for researching gold-bearing minerals using a process mineralogy detection system:
[0019] Take the study of flotation gold concentrate as an example.
[0020] 1. Sample preparation: Solidify, grind and polish the flotation gold concentrate sample to obtain a sample grinding piece; if the sample particle size exceeds 2mm, the sample particle size must be controlled within 2mm by crushing.
[0021] 2. Sample detection: Put the prepared sample grinding piece into the electron microscope in the sample room of the process mineralogy detection system, and the electron microscope is vacuumed to less than 2.5×10 -3 Pa, adjust the saturation point, displacement and tilt of the filament, the centering and astigmatism of the lens barrel, the gray scale standardization and detection base at 180Kcps, adjust the brightness and contrast,...

Abstract
The invention discloses a method for researching gold-containing minerals by using a process mineralogy detection system. The method comprises the following steps: sample preparation; sample detection; treatment of a detection result; preliminarily experimental study; development of preliminary experiments under various conditions; detection of a preliminarily experimented product; preparation ofa sample from the corresponding preliminarily experimented product for detection; determination of a technological process of a deep experimental research according to a detection result; deep experimental research: deeply developing targeted experimental researches; detection of a deeply experimental product: determining an existing state and a recycling possibility of gold in the corresponding product; mutual corroboration: performing mutual corroboration on experimental data and a process mineralogy detection result so as to guarantee real and reliable data. The method has the advantages that the method is suitable for treating various gold-containing minerals and selecting and smelting finished products, and the finally acquired data is accurate and reliable.
