GB/T 7739.15-2025 Methods for chemical analysis of gold concentrates—Part 15:Determination of platinum group elements contents

Scope

This document describes the method for determining the amount of platinum group elements (platinum, palladium, rhodium, iridium, and ruthenium) in gold concentrates.
This document is applicable to the determination of the amount of platinum group elements (platinum, palladium, rhodium, iridium, and ruthenium) in gold concentrates. Method 1: Lead gold concentration - inductively coupled plasma mass spectrometry Determination range: platinum 10.00 ng/g to 100,000.00 ng/g, palladium 15.00 ng/g to 22,000.00 ng/g; Method 2: Nickel sulfide gold concentration - inductively coupled plasma mass spectrometry Determination range: platinum 10.00 ng/g to 100,000.00 ng/g, palladium 10.00 ng/g to 100,000.00 ng/g, rhodium 10.00 ng/g to 100,000.00 ng/g, iridium 10.00 ng/g to 100,000.00 ng/g, ruthenium 10.00 ng/g to 100,000.00 ng/g.
