water consumption for grinding plants

Water Consumption by Agricultural Plants (Chapter 1 ...

Water consumption by agricultural plants normally refers to all water evaporated from plant and soil surfaces plus that retained within plant tissues. However, the amount of water retained within the tissue of agricultural plants generally is less than 1% of the total evaporated during a normal growing season. Therefore, water consumption as used in this chapter essentially involves water ...

The water loss in the concentrator (the moisture in the product) accounts for only 0.5%. In iron ore concentrator plants, which have higher product mass yield than copper plants, the water consumption increases to 15% at the concentrator and decreases to 85% at the tailings dam. In both plants the water consumption in the tailings dam is high.
