Equal quantities of mercury (500 g) and Sudha churna (limestone-500 g) are taken into a mortar and triturated for 36 hours (3 hours for 12 days). Mercury is collected from limestone filtered through a cloth. The remaining mercury is obtained by washing it with warm water. The wet powder of limestone is allowed to dry.

Decarbonising the lime industry: State-of-the-art
The thermal treatment of limestone (mainly CaCO 3) to produce lime (CaO) is a major contributor to CO 2 emissions and the literature on decarbonising the lime industry is scarce. Subsequent hydration of lime would lead to the synthesis of slaked/hydrated lime Ca(OH) 2; the production of a tonne of Ca(OH) 2 emits ∼1.2 …

of the softening plant. Hydrated lime is generally used more in smaller plants because it stores better and does not require slaking (producing a chemical change in lime by combining it with water) equipment. On the other hand, quicklime costs less per ton of available calcium oxide and is thus more economical for use in large plants.

Lime Slurry for Water Treatment
Both quicklime and hydrated lime are dry bulk products derived from limestone (calcium carbonate, CaCO 3). The calcium oxide material known as Quicklime (sometimes called lime) is produced by heating limestone in a kiln to drive off carbon dioxide (calcination). Adding water to quicklime initially produces dry hydrated lime.
