Germany is the world’s leading lignite coal producer. The region surrounding the towns of Cottbus and Senftenberg in Lusatia, Eastern Germany, is one of the largest mining areas in Germany, and has economically been strongly dependent on lignite mining and lignite processing industries since the...
Geochronology and Trace Element Characteristics of Pyrite from Selected Carbonate Hosted Pb-Zn Ore DepositsDownload
Carbonate-hosted ore deposits, such as Mississippi Valley-type (MVT), and Irish-type deposits, are a major class of Pb-Zn ores. Due to the mineralogy of these deposits, numerical constraints on the timing of mineralization are few. This thesis investigates pyrite Re-Os geochronology for dating...
In this study, the flotation behaviors of chalcopyrite and pyrite single and mixed minerals in Milli-Q water, NaCl solution, and sea water were investigated. The performance of different collectors was evaluated. Collectorless flotation was also studied under potentiostatic control to explore the...
During separation of emulsified water from oil, a viscous intermediate layer builds up between water and oil phases. This layer which is referred to as rag layer disrupts emulsion destabilization and water removal. The present research is intended to better understand the formation of a rag layer...
