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.
