-
(University of Pretoria, 2007-02-22)Equations for determining the electromagnetic response for a dipole situated above a layered earth are derived from Maxwell's equations. The theory is then expanded to allow for a transmitter and receiver at any distance ...
-
(University of Pretoria, 2007-02-21)This study aims to investigate the exploitability of the pegmatite deposits in the lower Orange River area, situated between the settlements of Vioolsdrif, Henkries and Steinkopf in the Northern Province, in the light of ...
-
(University of Pretoria, 2007-12-21)In this thesis, results of experimental investigations in the dry system PtS-PdS-NiS at 1200°C, 11 OO°C, 1 OOO°C, 900°C, 800°C, and 700°C are presented. Experimental results are compared with analyses of naturally occurring ...
-
(University of Pretoria, 2007-12-20)Gold mining in South Africa resulted in vast volumes of waste material, mainly in the form of tailings material. Poor management of most of the tailings dams resulted in the release of acid mine drainage that in some cases ...
-
(University of Pretoria, 2010-01-26)The research portrayed in this dissertation aims to derive empirical means of predicting CBR values from index testing parameters and parameters calculated from them (e.g. shrinkage product). The project involved compiling ...
-
(University of Pretoria, 2006-12-04)Groundwater is an important natural resource and ought to be protected. Groundwater recharge and contamination are two important aspects in groundwater management. Both these aspects apply to the vadose zone. The research ...
-
(University of Pretoria, 2013-01-09)Coal is a chemical compound with a complex composition. Proximate and ultimate analysis as well as physical and mechanical tests which are available do not furnish all the information required by industry. Information ...
-
(University of Pretoria, 2009-12-08)The work for this thesis was conducted on the basement lithologies of the Limpopo Province in South Africa. An investigation into the correlation between structural geology and the flow/occurrence of groundwater was conducted ...
-
The effect of mineralogical variation in the UG2 chromitite on recovery of platinum-group elements (University of Pretoria, 2006-11-30)Platinum-group elements (pGEs) are recovered from UG2 chromitite by milling and flotation. The mechanisms involved during beneficiation of this type of ore are still poorly understood, partly because of its complex nature. ...
-
(University of Pretoria, 2012-11-22)The economic development of South Africa has relied heavily on coal mining and water quality is adversely affected by mining - thus coal mining poses a significant risk to South Africa’s water resources. Ensuring judicious ...
-
(University of Pretoria, 2012-11-22)The Bushveld Igneous Complex (BIC) is the largest layered mafic intrusion in the world and contains the largest known deposits of vanadium, chromium and Platinum group elements on the planet, as well as large deposits of ...

-
(University of Pretoria, 2012-11-12)The most widely advocated method of carbon capture and storage involves the injection of CO2 into underground geological formations. Key to the development of this geological sequestration technology is the existence of ...
-
(University of Pretoria, 2012-11-12)The coalfields of South Africa contain numerous dolerite intrusions, which are believed to have affected the quality of the surrounding coal by a thermal process, controlled by the size of the magmatic body. Data gathered ...

-
(University of Pretoria, 2011-10-31)Stratiform chromitite layers are peculiar to large layered mafic intrusions. The origin of these chromitite layers has been widely debated. Some petrologists suggested that the layers formed as a result of the mixing of ...
-
(University of Pretoria, 2012-10-22)The study area comprises the Archaean Manica Greenstone Belt and the Vumba Granite Gneiss, the Proterozoic Messica Granite Gneiss of the Zimbabwe Craton, the possibly allochthonous metasedimentary sequence of the Frontier ...
-
(University of Pretoria, 2008)This dissertation collates all available data from the Department of Water Affairs and Forestry’s (DWAF’s) National Groundwater Database (NGDB), DWAF’s Groundwater Resource Information Project (GRIP) and tests conducted ...
