in infrastructure costs. Mining and ore dressing are linked by the dressing grade, which is determined by the average grade of the ore deposits, the head grade and the dilution rate, and which affects both the metal recovery rate and the concentrate grade. Given that the optimal head grade and dressing grade can improve both the utilization of ...

The first process most ores undergo after they leave the mine is mineral dressing (processing), also called ore preparation, milling, and ore dressing or ore beneficiation. Ore dressing is a process of mechanically separating the grains of ore minerals from the gangue minerals, to produce a concentrate (enriched portion) containing most of the ...

The first stage in ore dressing (or mineral beneficiation) is comminution or size reduction in order to liberate valuable minerals from the gangue. Information on the size and intergrowth relationship (textures) of minerals isof great importance from this point of view. The optimum grain size for effective liberation can only be determined by a ...

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.
