Dolomite is a double carbonate of calcium and magnesium (CaC03, MgC03). It is one of the important raw material used in iron & steel, ferroalloys, glass, alloy steels, fertilizer industry etc. Dolomite chips are also used in flooring tiles. 1. The present status of specifications of dolomite for different end use industries and the likely ...In this paper, the analytical results of the deposits, that is, 4 kinds of sands and 5 kinds of muds from the sea-coast of Hiroshima prefecture are described. Of the shallow- water deposits we have analysed, the sands in the present paper are exceedingly high in Si02 and low in Fe203, Al203, CaO, MgO, etc.

The pyrochlore deposit of Araxa, Brasil, is widely recognized today as the world's largest known niobium reserve. represents more than 70 percent of the world's economically extractable known reserves, has been mined by CBMM (Companhia Brasileira de Metalurgia e Mineracao) since the beginning of the 1960's and, for the last fifteen yearsAn average of 15.25 was received for crushed-dried, while calcined baux ite brought $12.38 per ton. There are no commercial deposits of bauxite known in the western states; however, there are deposits of high-alumina clays, alunite, and leucite. Alunite is a basic potassium aluminum sulphate, KAl)(OH)6(S04)2.
