The feasibility of non-water reaction polymer grouting technology application in seepage prevention for tailings reservoirs
Tailings reservoirs generally consist of a tailings dam, a tailings conveying system and a drainage system, which are indispensable facilities and provide security and environmental protection for storing tailings and clarifying water in some industries (e.g., metallurgy, non-ferrous building materials, nuclear and chemical industries). Consequently, consolidating seepage prevention and ...

Large-Scale Cover Trial of Tailings Dam, Heap Leach Facility and PAF Waste Dump at Nifty Copper Operation Case Study
Nifty Copper Operation has three waste landforms with highly saline materials: tailings dam, heap leach facility and a PAF waste dump. Once rehabilitated, potential exists for salts from these wastes to rise via capillary action into the cover material. Two large-scale trial plots were installed on each of these landforms in June 2015 following preliminary water and solute balance modelling. The ...

10 Common Questions When Choosing Earth Shield Geomembrane
1. What are the main reasons for using Earth Shield geomembrane in landfills? An important issue in landfills is the pollution control of leachate. After the landfill starts, a large amount of sewage is generated due to the influx of rainwater and surface water and the decomposition of the garbage itself. This is what we call leachate. This liquid has a high content of pollutants and a complex ...

Less and More : Why You Should Pump Slurries with a Peristaltic Pump
LESS WATER Peristaltic Pumps Use Less Water Hose pumps can circulate slurry SGs of 1.6 to 1.8 or up to 80% solid content. The traditional centrifugal pump loses efficiency when the slurry SG reaches 1.3 or 30% solids. With this limitation, slurry pumps have significant process water demands : on a plant processing 70 tonnes of ore per hour, every time a hose pump replaces a process slurry pump, ...
