Examining the use of Fluorspar in the Cement industry

Its inclusion in the process does not behave the same way in all cement kiln systems, so lab and industrial tests are always needed prior to industrial use. Due to the nature of cement process almost any quality of fluorspar or its sub-products(i.e. HF industry residues) can be used for cement production (as low as 40% of CaF2 content) 20
