Summary: This standard specifies the method for determining the content of silicon dioxide in bismuth concentrate by silicon molybdenum blue spectrophotometry and gravimetric method. This standard is applicable to the determination of silicon dioxide content in bismuth concentrate, with a determination range (mass fraction) of 0.50% to 20.00% for silicon molybdenum blue spectrophotometry and a determination range (mass fraction) of 20.00% to 40.00% for gravimetric method.
