Full title and description

ISO 10251:2006 — Copper, lead, zinc and nickel concentrates — Determination of mass loss of bulk material on drying (PDF). This International Standard specifies the method to determine moisture content of lots of copper, lead, zinc or nickel concentrates by measuring percentage mass loss of a moisture test portion under specified drying conditions.

Abstract

Specifies procedures for determination of moisture content (expressed as percentage mass loss) of bulk concentrates of copper, lead, zinc and nickel. The standard defines the drying conditions to be used for the moisture test portion and excludes application to samples intended for determination of volatile elements (for example mercury and sulfur).

Key bibliographic and lifecycle details above are taken from the ISO record for ISO 10251:2006.

Scope

Gives a standardised method for determining moisture content of lots of copper, lead, zinc and nickel concentrates by drying a specified test portion and calculating the percentage mass loss. The procedure is intended for bulk-concentrate moisture testing and is not applicable where drying is used for determination of volatile elements such as mercury and sulfur.

Key topics and requirements

• Definition of moisture test portion and sampling considerations for bulk concentrates.
• Specified drying conditions (temperature, duration, oven type and sample handling) required to obtain reproducible mass-loss results.
• Calculation method for moisture content as percentage mass loss of the test portion.
• Limitations and exclusions — not applicable for samples intended for volatile-element determinations (e.g., mercury, sulfur).
• Requirements for reporting results and any required precision or repeatability notes.

Typical use and users

Used by mining and metallurgical companies, laboratory analysts, quality control and assay laboratories, freight and trading organisations handling concentrates, and regulatory or inspection bodies that need a standardised moisture-determination method for concentrate lots.

Related standards

ISO 10251:1997 (previous version, withdrawn) and a committee draft/revision under development (ISO/CD 10251) are referenced in the ISO lifecycle for this standard. Other related documents include standards and methods for sampling of mineral concentrates and general analytical drying procedures maintained by ISO technical committees responsible for minerals and metalliferous materials.

FAQ

Q: What is this standard?

A: ISO 10251:2006 is an International Standard that specifies a method to determine moisture content (percentage mass loss on drying) for bulk concentrates of copper, lead, zinc and nickel.

Q: What does it cover?

A: It covers preparation of a moisture test portion, prescribed drying conditions, calculation of mass loss as moisture content, and reporting. It explicitly excludes use for samples meant for volatile-element analyses (for example mercury and sulfur).

Q: Who typically uses it?

A: Metallurgical laboratories, mine-site and concentrator QA/QC teams, third‑party assay houses, trading and shipping agents handling concentrates, and regulatory or inspection bodies involved in trade and quality verification.

Q: Is it current or superseded?

A: The 2006 Edition (Edition 2) was published in May 2006 and was last systematically reviewed and confirmed on 8 October 2020; the ISO record indicates the publication remains current but shows a lifecycle stage of "to be revised" with a committee draft under development. (Publication: May 2006; confirmation: 8 October 2020; revision stage noted on the ISO record.)

Q: Is it part of a series?

A: It is a standalone ISO method for moisture determination of specific metalliferous concentrates; the ISO lifecycle also references the earlier ISO 10251:1997 version and a developing committee draft (ISO/CD 10251) for revision.

Q: What are the key keywords?

A: Moisture, drying, mass loss, copper concentrate, lead concentrate, zinc concentrate, nickel concentrate, metallurgical analysis, sampling, moisture content.
