Lime Manufacturing Process. Limestone is a naturally occurring and abundant sedimentary rock consisting of high levels of calcium and/or magnesium carbonate, and/or dolomite (calcium and magnesium carbonate), along with minerals. 1. Extraction and stone preparation. Lime production begins by extracting limestone from quarries or underground mines.

Calcium carbonate (CaCO 3) is the most widely used filler in polymer formulations. As a filler, calcium carbonate allows cost reduction and improved mechanical properties. It is found in sedimentary rocks (chalk, limestone), marbles and minerals (dolomite). Some typical properties are: density 2.7-2.9 g/cm 3; pH of water suspension 9; particle

Calcium carbonate is divided into two industrial categories: Ground Calcium Carbonate (GCC) and precipitated calcium carbonate (PCC). The two categories use different manufacturing methods.
11.17 Lime Manufacturing 11.17.1 Process Description 1-5 Lime is the high-temperature product of the calcination of limestone. Although limestone deposits are found in every state, only a small portion is pure enough for industrial lime manufacturing. To be classified as limestone, the rock must contain at least 50 percent calcium carbonate.

Limestone formations are formed by natural precipitation, a process that occurs slowly. This is part of the explanation why the material in limestone products is completely converted to the CaCO3 form. By contrast, depending on the conditions of its production, precipitated calcium carbonate may contain some residual calcium hydroxide.
