Surface subsidence induced by underground mining is one of the challenging problems in mining engineering, which can destroy ground surface buildings and cause huge economic losses to the mine. In this study, a twodimensional numerical model, established by the discrete element method code PFC2D, was adopted to investigate the mechanical mechanism of surface subsidence and backfill .

Where recovery is currently uneconomic, opportunities may exist for improvements in mineral processing of ores to extract critical commodities as byproducts. A further conclusion of the study is that most of the critical commodities can be grouped into three families of mineral systems, as follows.

Jun 06, 2019· Mineral processing refers to a number of interrelated procedures that are all aimed at extracting valuable material from ores. Many valuable minerals are mined as ores, which are rocks that contain useful substances. Mineral processing was done by hand in the past, though in modern times it is typically achieved through the use of heavy machinery.
