The thermal treatment of serpentine from the locality Ljeskovac, Croatia, was studied in order to reach optimum characteristicsfor the inorganic acid leaching process. The fine and pure hydromagnesite and silica powder are main final products of the

Thorough kinetic analysis of the magnesia leaching based on measuring the changes in lixiviant composition revealed that there are differences between the actual leaching behaviour and predictions obtained using the non-porous shrinking particle mode

The dissolving potential of the Ca–minerals in concrete and limestone; and precipitation potential of metal ions from model acid water has been examined with attention to change of pH during the batch tests (L/S ratio = 300 ml /0.5 g, L = model sol

While the published research papers describe preparation of amorphous silica from water glass or using special methods (e.g. hydrolysis of alkoxides), the present study demonstrates a feasible solution for the cheaper synthesis of highly reactive sil

Slovakia holds 4th to 5th position in the world with respect to the supplies and mining output of magnesite. The most important product of natural magnesite processing is magnesia. While dead-burnt magnesia is used for producing basic refractory mate

Leaching of particulate dead-burned magnesite with hydrochloric acid at 45 °C was investigated with special regard to the effectof acid concentration (from 0.1 M to 4.8 M) on the rate of chemical dissolution of magnesium, calcium and iron. The leach
