Determining hydraulic parameters of a karst aquifer using unique historical data from large-scale dewatering by deep level mining – a case study from South Africa
(Water Research Commission, 2014)Although karst aquifers constitute some of the most important water resources worldwide, generally accepted methods for reliably characterising their hydraulic properties are still elusive. This paper aims at contributing ... -
The effect of particle size on the rate and depth of moisture evaporation from coal stockpiles
(SAIMM, 2016)Excessive amounts of moisture in product coal can influence the efficiency of downstream utilization processes due to a decreased calorific value and handling problems. Stockpiles can be used to decrease the moisture content ... -
Fine coal dewatering using high airflow
(Taylor & Francis, 2014)Fluidized bed drying is currently receiving much attention as a dewatering option after the beneficiation of fine coal. Apart from concerns about safety and combustion, the operating costs can be high if very high gas or ... -
Moisture transport during contact sorption drying of coal fines
(Taylor & Francis, 2020)Studies have shown that contact sorption drying is a feasible technique to dewater fine (+0.15mm–0.5mm) and ultra-fine (−0.15 mm) coal. The aim of this article is to further investigate the drying mechanism involved. It ... -
Unearthing a hidden treasure: 60 years of karst research in the Far West Rand
(Acad Science South Africa A S S Af, 2015)Karstified dolomitic formations situated in the Far West Rand goldfield of the Witwatersrand Basin constitute a significant groundwater resource in semi-arid South Africa and would be of strategic importance for alleviating ...
