The Journal of the Southern African Institute of Mining and Metallurgy VOLUME 120 SEPTEMBER 2020 515 Consideration for declaring a Mineral Reserve for TSF mining projects Rupprecht Synopsis The mining of old tailings storage facilities (TSFs) or dams/dumps has become a common operation in South Africa.
The mineral ilmenite is the major source of rutile for industrial use and is of interest to paint and fertiliser industries. Enormous unutilised tailing dams lie on the eastern coast of the South Africa. Although covered by a simulation of the original indigenous vegetation these tailings are still ilmenite bearing and of economic value. Tailings emanating from beach sand mineral slimes dams

Typically tailings are pumped as a slurry to a storage dam following similar engineering principles to water storage and hydroelectric dams. That is a tailings dam has to be designed and engineered to address risks such as flooding ( 1in100 or 1in1000 year storm events) seismic events (especially in some parts of the world

A tailings dam is typically an earthfill embankment dam used to store byproducts of mining operations after separating the ore from the gangue. Tailings can be liquid solid or a slurry of fine particles and are usually highly toxic and potentially radioactive. Solid tailings are often used as part of the structure itself.
This is particularly the case for tailings dumps created from the processing of platinum group elements (PGEs) from the UG2 reef in the Bushveld Complex (BC) of South Africa which are now being retreated to recover chrome.
Harmony currently has 85 tailings storage facilities under management in both South Africa and Papua New Guinea. These consist of 24 operational facilities 10 remining facilities and 51 dormant and inactive facilities. 19 of our operational facilities are constructed by means of upstream deposition which incorporates day wall and basin
Forty four years ago a platinum tailings dam operated by the Bafokeng Mine failed tragically. Tailings from the dam flowed 45 km flooding a mine shaft trapping and killing 12 miners. Bottom left
Converting Tailings Dumps into Mineral Resources Energy . Several commercially profitable enterprises have also been set up with the sole intention of retreating tailings dumps arising from South Africa s Witwatersrand gold processing operations According to Munyar Chirisa a chemical engineer and senior manager of Deloitte any tailings dump can be considered a potential mineral asset as long
