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

The ore dressing wastewater can effectively remove suspended solids from the wastewater through the tailings dam and the content of heavy metals and flotation reagents can also be reduced If the emission requirements are not met further treatment should be carried out

The first process that most of the ores or minerals undergo after they leave any mine is mineral processing or mineral ore dressing It is a process of ore preparation milling and ore dressing
