Applying a benchmark method to identify utility cost-saving opportunities on a platinum mine
(North-West University (South Africa)., 2022)
South Africa’s energy and water demands are more significant than the supply thereof. This higher demand means Eskom cannot deliver enough power to South Africa. Furthermore, South Africa is a water-scarce country and water ...
Using simulation to prioritise implementation of platinum mine compressed air efficiency solutions
(North-West University (South Africa), 2021)
Platinum mines are facing several challenges and a higher-than-inflation increase in electricity costs is amongst the most significant. Compressed air accounts for up to 38% of a platinum mine’s energy consumption. To ...
Evaluating the feasibility of integrating mine compressed air systems for energy savings
(North-West University (South Africa), 2021)
The South African metals and mining industry is under pressure to increase their production output. While South Africa’s production trend has been decreasing, even though it is the third largest gold reserve, the global ...
Future mine compressed air planning using digital twin simulations
(North-West University (South Africa)., 2023)
Most deep-level gold mines use compressed air services for various applications that directly influence gold production. Amongst others, these applications include drilling, agitation and loading boxes. However, similar ...
Target profiles for critical parameters in compressed air systems to reduce missed energy savings opportunities
(North-West University (South Africa)., 2023)
The reducing profit margins of South African mines pose a financial and economic risk for South Africa. The decrease in gold production and the increase in operational costs are contributing factors to the reduction of ...
Utilising automated control principles to reduce compressor operating costs on mines with limited infrastructure
(North-West University (South Africa)., 2023)
The mining industry faces severe challenges with increasing operating costs at above-inflation rates, particularly the cost of electricity. Compressed air systems are extensively used on mines, making up roughly 20% of the ...
