§ç §×nh To¸t, Phan ViÕt Nh©n, Ph¹m Ngäc Minh
In the §¾k Uy District, Kon Tum Province, the dolomite minerals exist in ore bodies stituated in the A V¬ng Formation, that were subjected to complex regional and dynamic metamophisms. The results of research have been showing that content of dolomite occupies >80%, MgO = 17.03 – 21.27%, 19.67% in average, CaO = 22.68 – 37.27%, 29.94% in average, SiO2 = 0.25 – 8.35, 3.56% in average, Fe2O3 = 0.03 – 0.72%, 0.22% in average, and low content of harmful mixtures. The dolomite is of high compressive resistance with the average compression strength of 872 kg/cm2. These mineralogical, chemical and mechanical properties of dolomite in §¾k Uy show that they can meet the requirements of many industrial and agriculture fields. However, with the recent economic situation of the country, dolomite in §¾k Uy are most effectively used for aquaculture, glass production for the B×nh D¬ng Glass Company and fire-brick production.
