SYNOPSIS: This paper discusses the geotechnical investigation of a large gold tailings facility which. has been in operation since December 1977. The very thorough test program included 670 m (2200 ft.) of piezocone probing, 65 selfboring pressuremeter tests down to a maximum of 35 m (118 ft.), 60.
Tailings management is a key challenge for mining companies and has been the source of increased public scrutiny, particularly following the recent tragic loss of life following the failures of iron ore tailings dams in Brazil. Detour Gold views safe and sustainable tailings management of .
Jan 18, 2016· The basin has led to a legacy of some 400 km 2 of mine tailings dams (270 tailings dams and 380 mine residue dumps) containing 6 billion tonnes of pyrite tailings and 600,000 tonnes of lowgrade uranium . The gold mining area studied has 5 mine tailings that have been accumulated throughout the operating history of the mine.

of mines producing gold, silver, and lead. The mine tailings left behind turned the creek orange as it ran to the Boulder River. "In 1998 when officials from Geological Survey tested the water, using live fish tests, all the fish died within 72 hours."3 Other tests conducted by the state of Montana found high
Jun 07, 2016· According to RESRAD, the maximum TEDE from gold mine tailings during 100 years was found to be mSv/year at year 30 compared to a value of mSv/year from the control area. In both areas, 232 Th contributed the most to TEDE, while 40 K and 238 U had lesser effect.
