• 5% of R.Silica is equivalent to 6.7% of Total Silica, which may go up to to 7-8% during mining as both top & bottom profile of bauxite are highly undulating in nature. So every 1% excess of R.Silica results more consumption of caustic soda and creates digestion problem. • Hence, threshold value of Silica in bauxite ore should be based on ...
