Abstract:

The laboratory of Hansteel Mining Subsidiary has worked out the best conditions and most reasonable method for measuring lime reactivity with optimized acid-base nitration method through laboratory experiment. The adoption of the optimized acid-base nitration measuring method shows that 10 times increase of the indicator concentration can make the final color change sensible, this has solved the issue of difficult observation and raised the accuracy of analyzed result and is favorable to control and improve the lime quality.
