Full title and description

AS ISO 19976.1:2020 — Copper, lead and zinc sulfide concentrates — Determination of cadmium — Part 1: Flame atomic absorption spectrometric method. This Australian adoption identically reproduces ISO 19976‑1:2019 and provides a validated laboratory procedure for determining the mass fraction of cadmium in sulfide concentrates.

Abstract

This document specifies a flame atomic absorption spectrometric (FAAS) method for the determination of the mass fraction of cadmium in copper, lead and zinc sulfide concentrates. The method is applicable, depending on the concentrate type, to mass fractions typically in the ranges 0.01 % to 0.30 % for copper and lead sulfide concentrates and 0.05 % to 0.30 % for zinc sulfide concentrates.

Scope

The standard defines sample preparation, instrument calibration, measurement and quality‑control procedures for FAAS determination of cadmium in copper, lead and zinc sulfide concentrates. It sets concentration ranges for which the method is intended and describes limits, interferences and procedural checks to ensure reliable laboratory results. The method is intended for routine laboratory analysis and trade/quality control applications.

Key topics and requirements

• Detailed procedure for sample dissolution/preparation appropriate for FAAS analysis.
• Calibration and standardization of the flame atomic absorption spectrometer, including calibration curve preparation and verification.
• Applicability ranges for cadmium mass fraction by concentrate type (copper, lead, zinc sulfides).
• Quality control: use of blanks, reference materials, repeatability and reproducibility checks.
• Interference identification and mitigation strategies for matrix effects common to sulfide concentrates.
• Reporting requirements and conformity criteria for laboratory results.

Typical use and users

Analytical and assay laboratories in mining and minerals processing, metallurgical quality control teams, contract testing laboratories, commodity traders, and regulatory agencies responsible for mineral product specification and trade commonly use this standard. It is used where FAAS is the chosen technique for cadmium determination and where the specified concentration ranges apply.

Related standards

ISO 19976 is a two‑part series. Part 2 (ISO 19976‑2:2019 / AS ISO 19976.2:2020) specifies an alternative acid digestion and ICP‑AES method for cadmium determination and is commonly referenced together with Part 1 when laboratories select the measurement technique most suitable to their instrumentation and required detection limits. Other related standards include national equivalents and practice documents for sample handling and reference materials in metallurgical analysis.

FAQ

Q: What is this standard?

A: AS ISO 19976.1:2020 is the Australian adoption of ISO 19976‑1:2019 and specifies a flame atomic absorption spectrometric method for determining cadmium in copper, lead and zinc sulfide concentrates.

Q: What does it cover?

A: It covers sample preparation, instrument calibration, measurement procedure, interference checks and quality control for FAAS determination of cadmium within the stated concentration ranges for the different sulfide concentrates.

Q: Who typically uses it?

A: Mining and metallurgical laboratories, commodity assay houses, QC teams in concentrators and smelters, contract testing labs and regulators use this standard for routine cadmium analysis and trade verification.

Q: Is it current or superseded?

A: The ISO parent document was published in 2019 and the Australian identical adoption was published in 2020; both are current publications. The ISO entry notes the standard is subject to periodic review (standards are normally reviewed every five years). Users should check their national catalogue for any later amendments or revisions.

Q: Is it part of a series?

A: Yes — ISO 19976 is a multi‑part series. Part 1 covers FAAS (this document); Part 2 covers acid digestion with ICP‑AES. Laboratories often consult both parts when selecting an analytical technique.

Q: What are the key keywords?

A: Cadmium; FAAS; copper concentrate; lead concentrate; zinc concentrate; metallurgical assay; sample prep; calibration; quality control; ISO 19976; Standards Australia.
