GB/T 6150.12-2023 Methods for chemical analysis of tungsten concentrates—Part 12:Determination of silicon dioxide content—Silicomolybdenum blue spectrophotometry and gravimetry
Abstract
This document specifies the method for determining the silica content in tungsten concentrate.
This document is applicable to the determination of silica content in tungsten concentrate and includes two methods (Method I: Silicon Molybdenum Blue Spectrophotometry; Method II: Weight Method). The determination range (mass fraction) of Method I is 0.50% to 10.00%; the determination range (mass fraction) of Method II is 3.00% to 10.00%. The overlapping part of the determination range shall be arbitrated by Method I.
