Summary:This is a paper in the field of metallurgical engineering. In order to solve the lack of mineral elements in pure water, increasing their concentration via the dissolution characteristics of mineral materials was a valid method. In this study, the dissolution characters of tourmaline in pure water were investigated and the tourmaline were characterized before and after immersing. The results showed that the immersing solution initial at acid pH value was in favor of the dissolution of mineral elements and its pH value was finally regulated to be alkaline. The increase of ratio of liquid to solid, immersing time and temperature could enhance the dissolved efficiencies of different mineral elements. The result of 30 d immersing experiment illustrated Mg, Al, Ca, Fe and Sr possessed durable immersing character of the mineral elements. The tourmaline’s surface morphology and mineral elements distribution before and after immersing experiments were also examined and it was found that there existed granular crystal
