Sonestie Janse van Rensburg. MINTEK, South Africa. sonestiejmintek.co.za 27 11 709 4731 ABSTRACT . In the West Rand, East Rand and Central Gauteng region it was estimated that there are more than 500 gold mining dumps of which 350 are in the Johannesburg region, covering about 320 000 hectares of surface area.
Gold mining in South Africa resulted in vast volumes of tailings, which have been deposited in impoundments. Poor management of most of the tailings dams resulted in the escape of seepage, adversely affecting soils and water quality. Some tailings dams have been partially or completely reclaimed leaving contaminated footprints. These zones pose a serious threat to the underlying
Dec 02, 2020 Gold Tailings amp The Environment. Owing to its gold mining heritage, Johannesburg is the most radioactive city on the planet, says nonprofit organisation Earthlife Africa. Uranium was considered merely a waste product in the late 1800s and was haphazardly discarded without any thought of recovery.
Tailings comprise crushed rock and process water emitted from the gold elution process in the form of slurry once gold has been extracted. As tailings contain impurities and pollutants, they are placed in tailings storage facilities engineered to contain them, in line with our tailings management programme.
