Flocculation of smithsonite and dolomite using polymers containing nitrogen atoms     

A.S. Śláczka  J. Paprotny 《International Journal of Mineral Processing》1985,14(4):319-325

The possibility was investigated of carrying out selective flocculation in the model set smithsonite-dolomite using polymers containing nitrogen atoms, which should interact selectively with zinc minerals.A high activity of flocculants in relation to smithsonite and a low activity towards dolomite was observed. However, the activation of the dolomite surface by Zn²⁺ ions was determined whereby the selective flocculation was not observed in the mixture of smithsonite and dolomite.  相似文献   

New estimates of potential impacts of sea level rise and coastal floods in Poland

Natural Hazards - Polish coastal zone is thought to be one of the most exposed to sea level rise in Europe. With mean sea levels expected to increase between 28 and 98 cm by the end of the...  相似文献
