What are Tailings
Tailings are a by-product of mining. After ore containing an economically-recoverable commodity is mined from the earth, that commodity is extracted in a processing plant or mill. After the commodity of value is extracted from the ore material, the resultant waste stream is termed "tailings". Typically, mill tailings range from sand to silt ...

Waste Water Recovery from Tailings
The recovery of wastewater from tailings requires a variety of approaches. These include in-place stabilization, Phyto stabilization, and capping. In order to determine which approach works best, an evaluation of four treatments was conducted. Tailings are waste generated during the processing of metal ore.

Tailings Pond and Mine Pit Water Treatment
Tailings ponds are used for temporary storage of waste materials left behind by the industrial mining process. These are filled with elements that are a hazardous byproduct and if not treated properly, can be toxic to the environment. The mixture in tailings ponds consists of waste created by the extraction process and water to create a slurry.
