How Lime is Made
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. Lime production begins by extracting limestone from quarries and mines. Sizing . . . Limestone enters a primary crusher to break the rock.

Slime Treatment By Flotation Process In Limestone Mine
In a limestone mine, a large amount of slime is washed off in order to remove impurities such as clay minerals. A fine sized calcite is, consequently, wasted and freight for carring the slime to reclaim land is expensive.
