study of ore samples. X-ray Fluorescence (XRF) is a method which is commonly employed for chemical analysis of the ore sample and determines the elemental composition of the ores [23, 24]. The technique makes use of X-rays to irradi-ate the sample, which after striking the sample results in the emission of secondary/uorescent X …

the extraction of gold in them is 81.12% (one-stage con-centration) and 84.29% (two-stage concentration). The gold content in the ore, calculated from the balance of experiments, is 2.71 g/t (test No. 1) and 2.11 g/t (test no. 2). To determine the granulometric characteristics of the material and the distribution of gold by size classes, a sieve

Deep mining has become an inevitable trend of mining development. Previously conducted studies have established that reasonable stope structure parameters are the premise to ensure the safe and efficient production of deep mines. In order to ensure the safety of deep mining, in this paper, we systematically review the existing …
