Drainage Control and Mine Dewatering at Faro Open Pit Mine ~ Drainage and dewatering programs have been mainly implemented in three areas of the mine: the Faro Creek diversion ditch outside of the pit limits, the Faro Valley, and the bottom of the open pit. These programs utilize a system of ditches, pipelines, sumps, pumps and inclined drainholes.
Review of Mine Drainage Treatment and Sludge Management ~ Review of Mine Drainage Treatment and Sludge Management Operations March 2013 The majority of the sites surveyed utilized sludge ponds for dewatering and permanent sludge disposal. On average, sites produced about 9,500 tonnes of dry sludge per year with production ranging from 20 dry tonnes to 135,000 dry tonnes per year. Depending
ACID MINE WATER TREATMENT USING THE HIGH DENSITY SLUDGE ~ Acid mine drainage is known as one of environmental problem which results from the mining operations, due to exposing the sulphide minerals to water and oxygen1,2.

Review on Dewatering Pumping Network for Underground Coal Mine ~ water, down the cone of dewatering towards the mine, to prevent the recharge of the aquifers in the mining area. (iii) Simple drainage methods, which is widely used in mines where the pumping capacity is sufficient to handle uncontrollable flows of groundwater. It is probably the simplest and most widely used drainage method
Mine dewatering techniques - SlideShare ~ Underground Mine Dewatering Techniques • In underground mines, the conventional approach is to allow groundwater to enter the workings, effectively using the mine itself as a drain • The water entering the mine is passed along roadways (by pumping or gravity) to a deeper part of the mine (sump) or shaft bottom, to be pumped out via shaft or .
Potential Implications of Acid Mine Drainage and ~ Acid mine drainage (AMD) is a persistent and extensive source of water pollution and ecological degradation. Cotreating municipal wastewater (MWW) with AMD using existing infrastructure at conventional wastewater treatment plants (WWTPs) may serve as a potential option for AMD abatement.
Innovation in Dewatering Sludges / IWA Publishing ~ This report will only be available as a Pay-Per-View item. Dewatering practices reduce the water content of sludges in order to minimise the volume to be handled and improve handling properties. Studies have shown that the ability of dewatering processes to reduce the water content is dependent on the specific dewatering process and the nature of the sludge.

[PDF] Flocculation and dewatering by Engineering ~ In this work, the lack of correlation between sludge rheology and dewaterability are demonstrated in two different types of conditioned sludge, namely flocculated sludge and oxidized sludge. In the first example, yield stress/maximum shear stress is the rheological parameter used to correlate with the dewatering index, CST, for flocculated sludge.
Sludge Dewatering - Environmental leverage Inc ~ Ok so we are going to dewater our nicely formed sludge. What are some of the critical components of dewatering? The first obviously is the polymer. Polymer selection, make-up, use of day tank, vs. Polyblend, pH, temperature of make up water, potable vs. non, cationic vs. ionic.
