  • Inclined plate settlers Fruitful Outotec

    In comparison to conventional thickening and clarifying equipment, the Fruitful Outotec inclined plate settlers (IPS) provide up to a 50% smaller plant footprint. The design of the parallel inclined plates allows the equipment to be constructed vertically instead of increasing the area needed.Water Control in Underground Mines Grouting or ,2012-2-19 · Dewatering of mines by the use of vertical wells drilled from the surface is a common practice, especially in open pit mines. The advantage of this system of dewatering is drainage ahead of mining, discharge of clean water, and practically no interference with the mining operation.
