Hydrated lime is used in the following applications:

Water and waste Treatment
Flue gas desulfurization
Agricultural application used for soil stabilization
Used in building products like mortars and stuccos
Used in plasters

There are two types of hydrated lime. They are Type N and Type S hydrated lime. This […]

There is a by product generated in the limestone calcination process. Process generates Lime kiln dust. It can be either in wet or dry form (wet or dry) and mostly consists of partially calcined quicklime and coal fly ash. This by-product also has variety of applications which includes environmental […]

Having seen the basic varieties of limestone (Calcium Carbonate) we can now discuss the products of limestone and how they are manufactured. One of the most widely used lime product is quick lime. This is nothing but calcined variety of limestone. The limestone is calcined in kilns to form […]

For using in Glass manufacturing application, the limestone should essentially have about 97% of Calcium Carbonate and 0.12% of Iron oxide. The Iron oxide content required limits vary according to the type of glass to be produced. The mentioned iron oxide limit of 0.12% is for manufacturing the standard […]

Limestone crushing is the most important step in processing the mined limestone. Generally limestone is crushed by dry grinding method and wet grinding method is not preferred for limestone crushing. There are special mills available in market for crushing limestone. Earlier traditional mills like Ball mills were used for […]

Next to Silica Sand and Soda Ash, Limestone is the major raw material used for manufacturing glass. About 14 - 18% of the raw material batch weight consists of limestone. Limestone is nothing but Calcium Carbonate (CaCO3). The limestone is added to the batch to provide the Calcium oxide […]

Solvay’s Process:
Ammonia recovery yield is controlled according to the permitted ammonia concentration in the released liquid. The lower the permitted value, the higher the quantity of stripping steam and therefore the global energy consumption, and the higher the cost of the ammonia recovery. This control can only be applied […]

Solvay’s Process:
One of the major achievements of the Solvay process is the high efficiency of the ammonia recycle loop. This loop circulates roughly 500 to 550 kg NH3/t soda ash from which the ammonia loss is less than 0.5 % of this flow rate. The purpose of this important […]

Solvay’s Process:
In some cases a small part of this “crude” bicarbonate, which although predominantly sodium bicarbonate also contains a mixture of different salts (ammonium bicarbonate, sodium carbonate and sodium chloride), may be extracted from the Solvay process cycle to be dried as “crude” bicarbonate product made without purification, by […]
