APPARATUS AND CHEMICALS Calcium Carbonate Content of Limestone Prepared by Paul C. Smithson, Berea College Using chips of limestone rocks, students prepare a powdered sample of limestone, react it with an excess of HCl, and determine calcium carbonate content of the limestone by back-titration of the unrteacted HCl. A practical
1.1 This test method covers the procedure to determine the percentage of calcium carbonate (CaCO 3)/magnesium carbonate (MgCO 3) in soils using sequential Loss on Ignition (LOI) test. 1.2 This ITM may involve hazardous materials, operations and equipment and may not address all of the safety problems associated with the use of the test method.
Calcium carbonate, which is found in eggshells and seashells, reacts with hydrochloric acid according to the following equation: CaCO3(s) + HCl(aq) ( CaCl2(aq) + H2O(l) + CO2(g) This reaction can be used to determine the mass percentage of CaCO3 in an eggshell sample. This can be accomplished in two ways.
The OFITE Calcimeter is used to determine the amount of Calcium Carbonate (CaCO 3) and Magnesium Carbonate (Dolomite) in a sample of alkaline earth carbonates such as oil well cores or drilled cuttings. Calcite build up in drilling fluids and in water .
The rate of carbonate mineral dissolution from limestone was studied using a rotating disk apparatus and samples of limestone of varied composition. The purpose of this study was to determine the effect of limestone composition on the kinetics of carbonate mineral dissolution. The results are needed to improve the relationships used to design limestone contactors for long term operation.

The volume of carbon dioxide they obtain can be converted to mass of calcium carbonate with the use of the graph. Knowing the mass of the sample of Tums used and the mass of calcium carbonate from the graph, they can determine the percent calcium carbonate in Tums. Figure 1.
Most important are calcium salts (salts of the carbonic acid): •calcium bicarbonate Ca(HCO 3), which only exists in aqueous solution, •calcium carbonate CaCO 3, not very soluble (approximately 15 mg/l for T=25 °C and 25 mg/l for T= 100 °C). Other elements, especially sodium .
the use of the graph. Knowing the mass of the sample of Tums used and the mass of calcium carbonate from the graph, they can determine the percent calcium carbonate in Tums. In Part 3, students perform the experiment using the general method of Slater and Rayner-Canham1 in which the calcium carbonate content of an antacid is
Conveying and Feeding of Calcium Carbonate in Plastics Compounding Introduction Calcium carbonate (CaCO3) is one of the most popular mineral fillers used in the plastics indus-try. It is widely available around the world, easy to grind or re-duce to a specific particle size, compatible with a wide range of polymer resins and economical.

A method and apparatus for the production of calcium carbonate and calcium silicate in common superatmospheric reactors. Multiple reactors (T-31, T-32) can be provided for switching production between reactors, and advantageously utilizing process waste heat. On site production of both PCC and Calcium Silicate Hydrates is thus achieved in a paper mill.
The use of the Carbonate Bomb can provide rapid and accurate measurements of the carbonate content of rocks and minerals. The program assists the user to obtain the best results from the equipment, and to evaluate the accuracy of the results.
