      This standard specifies the method for the determination of silica content in tin concentrates. Silicon molybdenum blue Spectrophotometric method, spectra-trophotometry is suitable for the determination of silica content in the range of 0.10% to 10.00%, while sodiumhydrate Titrimetric method is suitable for the determination of silica content between 5.00% and 20.00%. When the measurement ranges overlap, the sodiumhydrate Titrimetric method is used as an arbitration analysis method. The standard describes in detail the specific operation steps of sample handling, spectrophotometer determination and titration to ensure the accuracy of the results.
