A novel magnesium modified rice husk biochar (MRB) was synthesized for toxic metal stabilization prior to the vegetation reclamation of mine tailing. Manganese tailing was mixed with the amendments followed by 90 days of incubation to investigate the variation of Mn leachability as a function of...

The aim of this study was to investigate the role of MgO on the long-term operation of a mixed media contactor. Specifically, the simultaneous removal of aqueous manganese and the remineralization of soft waters using pure calcite is limited by a remineralization breakthrough after 600h of...

The aim of this project was to develop a detailed physical understanding of the thermodynamic and kinetic behaviour of precipitation in high manganese austenitic steels and to provide essential data for the modelling of technologically important (iron-carbide and transition-metal-carbide)...

Governments may decide to control the export of unprocessed raw materials hoping that this will promote local downstream industries. There is scant empirical examination of the actual outcomes of such policies put in place. This paper describes use of export control measures by four...

Unternehmenskonzentrationen im Weltbergbau warfen die Frage auf, ob die bisher problemlose Rohstoffversorgung der deutschen Wirtschaft über die Weltmärkte und ohne wesentliche eigene Rohstoffengagements im Ausland gefährdet werden könnte. In der Studie werden die Märkte von zehn...
