Distribution and dispersion of metals and their economic potential: a case of the Fumani Tailings Dam, Limpopo Province, South Africa
The study was conducted at the Fumani Tailings Dams 1 and 2 located in Malamulele, Mtititi village and the area surrounding it to investigate the distribution and dispersion of gold and metals such as Pb, Zn, Cu, As, Co, Cd, Cr and Ni, and also to determine their pollution status, whilst looking at …

Analysis of contributions to the PM10 concentration in a gold mine residential village
… possible and useful in comparing individual tailings dams contributions. The No. 4 tailings dam has been identified as one of the major contributors to PM10 concentration at West Village. The average PM10 gravimetric concentration recorded at West Village was 18.4 μg/m3 and the concentration …

Physical Modelling of Tailings Dam Breach
Tailings dams are constructed in stages, exhibit sediment deposits located in the reservoir upstream of the dam crest (beaches) generated from slurry deposition, and are commonly designed with shallower upstream slopes in contrast with conventional water storage dams. Current breach models for the …

Applying the Material Point Method to Identify Key Factors Controlling Runout of the Cadia Tailings Dam Failure of 2018
… thesis examines the 2018 failure of the Northern Tailings Storage Facility at Cadia Valley Operations, located in New South Wales, Australia. First, the importance of examining and understanding failure mechanisms and post failure kinematics is described. Within which we understand that in the …

Arsenic dispersion associated with the Barbrook gold mine in the Mpumalanga Province of South Africa
… metres with waste rock containing low grade ore. Tailings material from the processing plant is pumped to two tailings dams located about 5 km to the northwest of the plant and close to Crystal Stream.

The effect of flotation reagents on the coagulation and dewatering of flotation tailings
… especially in PGM mining, where flotation tailings pose serious difficulties. Water constitutes 80-85% of the mineral pulp in the flotation process, emphasising the significance of its role. However, water recycling from tailings dams and dewatering systems is becoming increasingly …

Comparison of Finite Element Methods and Satellite InSAR for Monitoring Deformations of a Large Tailings Dam
… the recent catastrophic failure of several mine tailings dams there has been much interest in the use of numerical modeling and remote sensing for monitoring the safety and stability of these structures. This thesis presents a case study that investigates the accuracy of InSAR measurements and …

Design parameters and management strategies of soil and rock slopes: Nchanga open pit-Konkola copper mines plc
… or mining works. Slope stability of pits, roads, tailings dams and other embankments is very cardinal as it directly impacts on the working or utilisation of these facilities. The Nchanga Open Pit has presented special challenges. This research is directed towards efforts to determine slope design …

Assessment of water pollution arising from copper mining in Zambia: a case study of Munkulungwe stream in Ndola, Copperbelt province
… solutes were impacted by closeness to the mine tailings deposit with the heavy metal concentration being highest at S2 and S3. Moreover, high turbidity levels revealed that land erosion induced by agriculture activities is a severe problem in the area. Physical parameters were high in the rainy …

Considering the action of frothers under degrading water quality
… their operations, which is usually sourced from tailings dams or concentrator thickeners. This means that the recycled water can contain elevated levels of dissolved solids which consist of various ions and other contaminants such as residual reagents. This presents a problem in the flotation …

An electrochemical investigation on the mechanisms of interfacial interactions of a xanthate collector on PGM surfaces in the presence of ions
… the recycling of process water is executed from tailings dams, thickener overflows, and dewatering and filtration units. The recycling of process water has been considered to be advantageous as it reduces freshwater consumption, lowers waste discharge and reduces volumes of reagents required in …
