| Abstract [eng] |
Reprocessing of phosphogypsum is becoming more and more relevant issue not only in Lithuania, but also in the rest of the world. Both, Lithuanian and for-eign scientists are trying to solve phosphogypsum reprocessing problem for a long time. However, phosphogypsum is still utilised by pouring it to the water, unexploited mines or by transporting to the dumps. General aim of the work is to propose new, effective additives neutralising acidic extractive hemihydrate impurities of phosphogypsum and effective me-chanical activation technology for phosphogypsum processing, which would allow to reprocess this largest amount of mineral technogenic waste materials in Lithuania to the high quality composite gypsum binding material and its const-ruction products. |
