Flange Classes Explained
Flanges are often referred to by class, or their lb. designation, or even just as a number followed by an octothorpe (the # symbol), which is the hashtag for you millennials, and the pound sign for everyone else. These terms are all used interchangeably to describe the pressure rating of a flange. To make things more confusing, a 600 pound flange does not correlate to a rating of 600 psi. So what ...

Use of a Finite Element Code to Model Complex Mine Water Problems
Abstract: Numerical models are now used routinely to predict ground-water inflows to both surface and underground mines and to help design dewatering systems. Two of the more complex problems encountered in mine dewatering are 1) predicting the configuration of the phreatic surface and height of the seepage face in pit highwalls for slope stability analysis and 2) predicting inflow to ...

Mine Dewatering in a Compartmentalized Hydrogeologic Setting at Sishen Mine in South Africa
Abstract: Sishen mine in South Africa is one of the largest open-pit iron mines in the world. It is characterized by a complex, compartmentalized hydrogeologic setting that comprised numerous dykes, regional water-bearing faults, and inter-bedded localized geologic units. The groundwater flow in the vicinity is mainly controlled by regional dykes and faults in a karst aquifer. A 3-D groundwater ...

Geotube Containment and Dewatering technology was used to dispose of slurry waste from North River Mine - Case Study
At the North River Mine in Berry, AL, two waste streams are created from the processing plant, coarse rock and fine rock particles. Coming from the processing plant, the fine rock particles are suspended in water forming a slurry. This slurry is normally disposed of via surface impoundments or injected into abandoned underground mine workings. The volume of this waste stream is very significant ...

Mitigating Environmental Impact Of Gold Mine Wastewater Through Ozone Oxidation And Aquifer Re-injection
US Environment Protection Agency (USEPA) regulations require mining operations to remediate their waste streams prior to environmental discharge. Wastewater streams from gold mine operations can be particularly toxic due to the potential for cyanide contamination and the concentration of metals contained in the wastewater effluent. This paper reviews the challenges and success of installing and ...
