Full title and description

ISO 10469:2006 — Copper sulfide concentrates — Determination of copper — Electrogravimetric method. This International Standard specifies an electrogravimetric procedure for determining the mass fraction of copper in copper sulfide concentrates (nominal range 15 % to 50 % m/m).

Abstract

ISO 10469:2006 defines an electrogravimetric analytical method in which a test portion of copper sulfide concentrate is decomposed and copper is selectively deposited and weighed to obtain the mass fraction of copper. The method is intended for concentrates with copper content approximately between 15 % and 50 %.

Scope

ISO 10469:2006 specifies an electrogravimetric method for determining the mass fraction of copper in copper sulfide concentrates. The procedure covers sample decomposition, chemical separation of copper from common interfering elements, electrodeposition of copper, and gravimetric determination of the deposited copper. The standard is intended for copper contents in the range 15 % to 50 % (m/m).

Key topics and requirements

• Sample preparation and representative test portion selection for concentrates.
• Decomposition of the test portion (acid digestion) and chemical treatment to remove interfering elements.
• Electrogravimetric deposition of copper onto a cathode and accurate weighing of the copper deposit.
• Procedures for checking and correcting interferences and losses (assessment of residues, filtrates and co-precipitated elements).
• Calculation of mass fraction of copper and expression of results.
• Applicability limits: recommended for copper sulfide concentrates with copper between ~15 % and 50 % m/m.

These topics are summarized from the ISO 10469:2006 scope and abstract.

Typical use and users

Typical users are analytical and metallurgical laboratories in mining and mineral-processing companies, independent assay and inspection bodies, research laboratories, and quality-control units in refineries and smelters that handle copper sulfide concentrates. The method is used where a gravimetric (electrolytic) determination of copper is required or preferred for accuracy and traceability.

Related standards

ISO 10469:2006 replaces ISO 10469:1994. Other ISO methods for copper and concentrates include titrimetric and other determinations (for example ISO 10258 series for titrimetric methods and ISO methods for electrolytic/electrogravimetric determination in other copper materials). National/adopted equivalents (BS ISO, NEN ISO, SAC standards) exist.

FAQ

Q: What is this standard?

A: ISO 10469:2006 is an International Standard that specifies an electrogravimetric method to determine the mass fraction of copper in copper sulfide concentrates (Edition 2, published July 2006).

Q: What does it cover?

A: It covers sample decomposition, separation of interfering elements, electrodeposition of copper, weighing of the copper deposit and calculation of the copper mass fraction for concentrates with copper content approximately between 15 % and 50 %.

Q: Who typically uses it?

A: Mining and mineral-processing laboratories, assay offices, metallurgical quality-control teams, inspection bodies and analytical research labs dealing with copper concentrates.

Q: Is it current or superseded?

A: The 2006 edition (Edition 2) supersedes ISO 10469:1994. ISO's record indicates the 2006 edition remains the current published edition (ISO review/confirmation history maintained by ISO). Users should check with ISO or their national standards body for any later revisions.

Q: Is it part of a series?

A: It is a stand-alone method for electrogravimetric determination of copper in sulfide concentrates but is related to other ISO analytical standards for copper and concentrates (for example titrimetric and electrolytic methods covered in other ISO documents and national adoptions).
