Chalcedonite is a sedimentary siliceous rock, which occurs at four deposits in Poland and is included into a group of unique rocks. Chalcedonite is utilized in water treatment technology, mostly as an effective fi ltration material due to its mesoporous structure and extended outer surface of the grains. This paper presents three different methods of impregnation of the mineral material (MDMC-1, MDMC-2, MDMC-3) by manganese dioxide. As an oxide carrier chalcedonite was used. The results of the chalcedonite surface modifi cation with SEM-EDS technique were presented. It was found that the chalcedonite is a very good manganese dioxide carrier and the modification of the chalcedonite surface changes its chemical composition, structure and value of the specific surface area.
