Lime is an important basic raw material for chemical industry. It is obtained from Lime Stone. Lime Stone is found in Maharastra, Andhra Pradesh, Madhya Pradesh, Rajasthan and Uttarakhand in India. But the quality of Uttarakhand belt in superior than the other belt found in India. Dehradun Lime Stone is very hard and heavy in weight as compared to other Lime Stone found in India. Due to the hardness of quick lime lumps it change in powder form, where as other Lime found in Rajasthan, Andhra Pradesh, Madhya Pradesh, Maharashtra are very soft and it can not stored for long time. It easily observed moisture and change in powder form. The Silica, Magnesia, Iron and other impurities are very less in Dehradun Lime Stone as compared to other Lime Stone found in India. The colour of the Dehradun Quick Lie is super snow white. Due to the above season the most of the chemical industry like the Dehradun Lime.

Specification: Our products are available under the following technical specification in which we can make available a different percentage of parameters like moisture, acid insoluble, mesh size etc.

Quick Lime

Quicklime (or calcium oxide or burnt lime) is obtained by calcining pure limestone at temperature above 9000C. This highly reactive product is essential to many industrial processes.

Dolomite Lime

Dolomitic quicklime is the name given to the quicklime formed from calcining a natural dolomitic limestone that contains nearly an equal molar weight percentage of calcium oxide to magnesium oxide. Ideally, this quicklime would contain 56% calcium oxide, 40% magnesium oxide, and 4% other major lime impurities such as iron oxide, aluminum oxide, silicon dioxide, and sulfur.
