Research on Online Sorting Method for the Gold Ore
摘要
Abstract
DAiming at the extra narrow veins of mine, the mining of ore and waste rock all into the post-processing, which will cause a great waste of energy, in this paper, visual inspection, laser induced breakdown spectroscopy, X-ray fluorescence method were adopted to analyze the gold ore and waste rock, distinguish the gold ore and waste rock by the characteristics of color difference, characteristic element content difference and so on, and pick out the waste rock that mixed in the gold ore. Through the test analysis of the three sorting methods, the feasibility of X-ray fluorescence online sorting was determined, which made a large number of waste rock can be discarded in the ore pre-selection phase. It not only improves the grade of raw ore, but also has great engineering application value.关键词
