GB/T 3884.16-2025 Methods for chemical analysis of copper concentrates—Part 16:Determination of silicon dioxide content—K2SiF6 titrimetric method and gravimetric method
Abstract
This document describes the methods for determining the silica content in copper concentrates and copper slag concentrates using potassium fluorosilicate titration and gravimetric methods.
This document is applicable to the determination of silica content in copper concentrates and copper slag concentrates. The measurement range (mass fraction) of Method 1, potassium fluorosilicate titration, is 0.50% to 32.00%; and the measurement range (mass fraction) of Method 2, gravimetric method, is 0.50% to 40.00%.
