Line. • XRF/XRD. Introduction. There is a growing demand and interest in the cement industry to monitor the concentration of line, of which calcium carbonate (CaCO3) is the main constituent in the final product. Recent European . The high energy of the incident radiation used allows a larger volume (about 10.
Three types of calcium carbonate-containing rock are excavated and used by industry. They are line, chalk and dolomite. Line and chalk are both forms of calcium carbonate and dolomite is a mixture of calcium and magnesium carbonates. All have impurities such as clay but some rocks are over 97% pure.
Calcium carbonate is strongly heated until it undergoes thermal decomposition to form calcium oxide and carbon dioxide. The calcium oxide (unslaked lime) is dissolved in water to form calcium hydroxide (limewater). Bubbling carbon dioxide through this forms a milky suspension of calcium carbonate.
There is an increasing demand and interest in the cement industry for monitoring line concentration, of which calcium carbonate (CaCO3) is the major constituent. . The high energy of the incident radiation used enables the analysis of a larger (about 10 times) volume of the sample than with XRF; this makes the XRD.

You need to be able to measure the amount of hydrochloric acid used in moles (you should measure the volume and you know the concentration. The number of moles of water is twice the amount of moles of the calcium carbonate (from the chemical equation above). You should measure the mass of the amount of shell.
