Oct 26, 2016 Gold mine tailings are characterized by poor physical properties like poor aggregation, high hydraulic conductivity, fine texture and very limited cohesion ability. These properties make tailings different from soil [19,20] and the lack of cohesion is responsible for the varied moisture content and temperature seen in this toxic waste.

Mining is not new to the region, however. Beginning in 1849, mining has taken place in numerous
Mine tailings are the finely ground residue from ore extraction. The grain size of the tailings depends on the nature of the ore and the milling process. Size measurements (Robertson, 1994) of tailings from four mines in Ontario, Canada, indicated the tailings materials to be predominantly silt and fine to medium sand with 10% clay content.
The exploitation and use of mineral resources produce large amount of mine tailings that are commonly in slurry form with high water content and compressibility. Over the last few decades, the volume of tailings being generated increased dramatically with the increase in the demand for minerals and metals, and the mining of many low-grade ores.
