The leaching of manganese (Mn) ore in sulphuric acid (H2SO4) under reductive conditions has been studied. The effects of leaching parameters such as ore/reductant mass ratio, acid concentration, ore particle size, solid/liquid ratio, leaching time an

Der Steinbruch am Flügel Jägerhorn westlich von Grillenburg ist vermutlich der älteste Kreidesandsteinbruch des Tharandter Waldes, in Betrieb seit etwa 1170. Historisch belegt ist, dass beispielsweise 1225 die Goldene Pforte des Freiberger St.-Mar

According to the theory of plate tectonics, rocks found in the vicinity of mid-ocean ridges — where oceanic plates are created — should be relatively young (at most several Myr old). Here we report the discovery of zircons with ages of about 330

Ein Umweltproblem des sachsischen Erzgebirges sind die Auswirkungen sowohl in jungster Zeit stillgelegter Bergbaubetriebe als auch in der Vergangenheit geschlossener Erzgruben. Ursache sind die in den abgeworfenen Grubenbauen verbleibenden, nicht bau
