Sedimentological and mineralogical characteristics of Limpopo River Sand at Beit Bridge Border between South Africa and Zimbabwe
… aimed to investigate the sedimentological and mineralogical characteristics of Limpopo River sand upstream of Beit Bridge, situated on the South Africa/Zimbabwe border. Due to limited information available about the minerals and sediments associated with Beit Bridge, this study was conducted to …

An investigation into the process mineralogy of the Merensky reef at Northam Platinum Limited
… has investigated the links between the mineralogical characteristics of the Normal, NP2 and P2 Merensky reefs at Northam Platinum Ltd and their flotation performances. Flotation performance was measured in terms of the grade and recovery of the base metal sulphides (chalcopyrite, …

Investigation on Revegetation/ Phytoremediation of Campo Pisano abandoned mine area
… halepensis Mill. was selected due to its special characteristics as a pioneer species growing spontaneously on Campo Pisano (CP) mine tailing, a multiple heavy metal contamination site in SW-Sardinia, Italy. The aim of this PhD thesis is to assess the phytoremediation capability of P. halepensis …

Metamorphism and Deformation in Early Proterozoic Basic Dykes Near Scourie, Northwest Scotland (Amphibolite)
… There is no correlation between the dyke characteristics and mineralogical or structural changes within the country rock. The mineralogical and deformational character of the dykes probably formed in association with, or closely following intrusion. The amphibolite facies mineralogy and …

Characterising the acid mine drainage potential of fine coal wastes
… particle size distribution, textural reference, mineralogical characteristics, and how the aforementioned factors influence the acid potential in coal. The approach intends to address key factors which include: identifying the sulphur bearing organic and inorganic constituents related AMD …

Developing proxies for routine measurement of ore hardness: A mineral sands case study
… hardness measurements vary depending on the characteristics of the ore, and need to be developed for each ore based on its geological and mineralogical characteristics. This study aims to develop geometallurgical proxies to predict the hardness of the cemented hard layers (CHLs) found in a …

Applicazione delle tecniche elettrosmotiche alla consolidazione dei fanghi di risulta dei processi mineralurgici
… of the deposited material, to its chemical and mineralogical characteristics (high concentrations of heavy metals) and to its high water content. Most of the tailing dams were built before 1980 and they are not really dams in the conventional water-retaining sense. They are more akin to a thick …

A comparative study of sediment characteristics of Sand River and Nzhelele River in Limpopo Province, South Africa
… study examined the textural, particle size, and mineralogical characteristics of the sediments from the Sand River and the Nzhelele River. At the mouth of each chosen river, a collection of recently deposition sediments was collected to get a representative sample of the watershed. With …

Characterising the potential health risks associated with coal dust
… however, no consensus has been reached on which characteristics are relevant to pulmonary toxicity. This study hypothesises that the toxic potential of inhalable coal dust can be attributed to reactive mineralogy and the specific surface area for interaction between the particles and primary …
