ASTM E389

Particle Size or Screen Analysis at 4.75 mm (No. 4) Sieve and Coarser for Metal-Bearing Ores and Related Materials

Applicability: ASTM E389 is a standard test method used to determine the particle size distribution of metal-bearing ores and related materials. It applies to screen analysis at the 4.75 mm (No. 4) sieve and coarser.

Purpose: The purpose of ASTM E389 is to measure the particle size distribution of coarse metal-bearing ores and related materials by screen (sieve) analysis. Results are used to determine compliance with specifications for particle size distribution.
