    Apr 10, 2017 Apr 10, 2017 Although perhaps not ore dressing in the strict sense of the term, the direct extraction of the metals (especially the precious metals) from the ores also is considered here as an ore-dressing or a “milling” process. Preparation by ore dressing includes the concentration of the valuable minerals within a smaller bulk than that of the

    The ore lumps from the mines have the lump size of 10 - 100 cm while the individual minerals have grain sizes below 0.1 mm. Hence, the first step in any ore dressing plant is to aim at liberation by size reduction or comminution. Comminution of any ore is carried out in several stages using different crushing equipments
