Washing is the process of treating ore that is cemented with clay or contains more mud. Washing is to wash off the clay or attached slime on the surface of the ore. The basic principle of washing is: the original ore is sprayed under water, washed and soaked, mechanically vibrated or agitated, and the friction of the ore itself, so that the muddy or clay that is entrained or attached to the surface of the ore is dispersed and eliminated with water. , thereby increasing the manganese grade of the ore. Essentially it includes two operations of ore and clay breaking and separation. Washing is generally carried out in conjunction with the crushing and screening process.
