Contact usCement accounts for 83% of total energy use in the production of non-metallic minerals and 94% of CO2 emissions. Energy represents 20% to 40% of the total cost of cement production. The production of cement clinker from limestone and chalk by heating limestone to temperatures above 950°C is the main energy consuming process.
Contact usIts 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
