Title: A study of the occurrence of magnesium oxide in different phases of limestone
Abstract: Abstract Distribution of MgO in dolomite, calcite and silicate phases in a magnesian limestone from a deposit of Orissa, India, was investigated. For estimation of MgO in calcite, selective dissolution of limestone in 20% ( V V ) acetic acid (at around 25 deg.C for 20 hours) is found to be the most suitable method. The optimal requirement of acetic acid in the stated dissolution process is found to be 10 ml. per gram of limestone. In the examined limestone, calcite contains 1.3-1.9% MgO and thus contributes about 11–45% of the total MgO present in the limestone. Associated silicate and dolomite are found to contain 9–21% and 19–23% MgO respectively.
