A comparison between high airflow drying and adsorption assisted drying for the dewatering of fine coal
(North-West University (South Africa), 2019)Development in the fossil fuel sector should be an on-going process to promote sustainability, while reducing the environmental footprint. It is important to improve operations in the mining sector to ensure that coal is ... -
Development of a dewatering control strategy to prevent flooding within deep-level mines
(North-West University (South Africa)., 2022)Deep-level mines are faced with continually increasing challenges regarding heat. New mining depths are constantly reached, and working conditions are becoming intolerable and unsafe. Underground conditions must be controlled ... -
Drying of fine coal using warm air in a dense medium fluidised bed
(2014)Fluidised bed drying is currently receiving much attention as a dewatering option after the beneficiation of fine coal (defined in this study as between 1mm and 2mm particles). The aim of this study was to investigate the ... -
Modeling power failures in deep-level mines to assist with emergency dewatering planning
(North-West University (South Africa)., 2023)A mining complex’s intricate dewatering system removes water that enters the shaft through various means. This system comprises a series of water pumps that require a constant power supply to avoid flooding key areas of ... -
Reconfiguring mine water reticulation systems for cost savings
(North-West University, Potchefstroom Campus, 2018)Rising electricity costs in South Africa force companies, including gold mines, to minimise their energy consumption (EC). More than 30% of the total energy demand for deep-level mines is consumed by the water reticulation ... -
Reducing energy consumption of a deep-level platinum mine dewatering system through infrastructure reconfiguration
(North-West University (South Africa)., 2022)South Africa is the largest producer of platinum in the world, accounting for up to 80% of global production. The mining sector contributes significantly to the South African economy, but this contribution is hindered by ... -
A techno-economic evaluation of the production of hard coking coal from Tshikondeni coal discards
(North-West University (South Africa) , Potchefstroom Campus, 2016)Tshikondeni Coal, operated by Exxaro Resources Limited on behalf of the owners, ArcelorMittal South Africa, is currently the only operational hard coking coal mine in South Africa. Therefore the yield from the plant needs ...
