The ability to discharge gangue means that this word is generally used in the mining industry. Gangue refers to gangue, that is, non-mineral miscellaneous stones (for example, iron ore or gangue in coal mines is not necessarily useless stones, but refers to stones unrelated to the main minerals). Generally, every mine will have a minimum proportion of gangue. If it fails to meet the national standards or the standards set by the mine itself, it is necessary to discharge gangue. Gangue is a stone mixed in coal seam, which contains a small amount of combustible materials and is not easy to burn. Commonly known as "gangue". Gravel extracted from underground or mixed with ore during mining. The thin rock layer in the middle of coal seam is called "stone inclusion". I hope my answer can help you! Seeking adoption ~
