Dear Mr. Yousefi

Calcining and decarbonization of limestone at temperatures of appr. 1100°C can yield a good lime. A high-quality lime-specification looks like that: 

>95  mol.-% CaCO3

Dear Prof. Dill

Thank you for your Clear and complete answer.

I want use lime for preparation of lime milk as precipitation agent (for mgnesium hydroxide precipitation). therefore, quality of lime and absence of impurities are very important in this method to increase purity of Mg(OH)2.

Sincerely, very Sincerely

Dear Mr. Yousefi,

after your evaluation based on the geological results you should carry out  mineralogical and chemical analyses to find out what sort of impurities detrimental to your final product exist in the kiln feed and to what extent they are present. Based upon these results you have to design your follow-up processing.

Best regards
