Molybdenum(VI) removal by using constructed wetlands with different filter media and plants
The efficacy and capacity of vertical-flow wetland filters on molybdenum (Mo) removal from wastewater was examined, employing reed (Phragmites australis) and cattail (Typha latifolia) as well as different adsorption granular media. Humus, cinder, modified cinder, as well as pyrite were used as filter media. A synthetic effluent with different concentrations of Mo(VI) at different hydraulic ...

Well-Field Mechanics for In-Situ Mining
Over the last several decades in-situ leach mining has become increasingly popular. Conventional mining produces tailings, runoff, and considerable land disturbance—all requiring significant rehabilitation. With in-situ leach mining methods (see diagram below), disturbance is reduced because only multiple boreholes are drilled for recovery. Rehabilitation is much simpler, consequently, the ...

How to Choose The Right Mining Geomembranes?
The mining industry is more and more popular in recent years, heap leach mining projects or bitumen mining have become the preferred method of recovering minerals, like Copper, gold, silver, and other metals are most common. The metal is dissolved by chemicals applied to the top of the heap, which eventually leach to the bottom of the pile. Here a mining geomembranes liner captures the solution ...

Recent Develoments in Uranium Mining Air Sampling Programs in the United States
Introduction and History Commercial uranium mining operations in the United States, beginning in the post World War II era, were primarily open pit mining. Open pit mining was the primary extraction method until in-situ recovery (ISR) began in the State of Wyoming in 1961. ISR is also known as in situ leaching (ISL), or solution mining. It is a mining process utilized to recover minerals, such ...

Interest Growing in Mining Applications for Geosynthetics
Some 40 percent of the geosynthetics manufactured today are used by the mining industry, according to one estimate, and there are predictions that figure will increase as the industry continues to adopt mining technologies that help improve efficiency and protect the environment. Jack Caldwell, an engineer at Robertson GeoConsultants, has gone as far as to say, “We believe that the ...

Designing With Geosynthetic Clay Liners
In construction, preventing the penetration of liquids and gases is essential to maintaining the integrity of a structure. Often, containment is just as important, especially when dealing with chemical contaminants or other waste. When looking to stop the spread of contaminated liquids and gases, there are few tools as effective as geosynthetic clay liners (GCL). Read on to learn how to design ...

A Calibrated Predictive Geochemical Model of Leaching and Attenuation Reactions in a Mine Pit Lake
Abstract: A geochemical model was developed to predict future water quality of the Cove pit lake in support of site closure and regulatory permitting. The terminal, groundwater-fed Cove pit lake began filling in 2001, and water-quality samples from the 15-year filling period were used to calibrate the pit-lake model and evaluate the accuracy of the predictions. Inputs to the pit-lake model ...
