ISO 10251:2006 specifies methods for the determination of moisture content of a lot of copper, lead, zinc or nickel concentrate, defined as the percentage mass loss of the moisture test portion under the conditions of drying specified in this document. ISO 10251:2006 is not applicable to drying samples used for determination of volatile elements such as mercury and sulfur.
Abstract
Overview
ISO 10251:2006 specifies standardized laboratory methods for determining the moisture content of copper, lead, zinc and nickel concentrates. Moisture is defined as the percentage mass loss of a test portion when dried under the conditions given in the standard. The document sets requirements for sampling, drying, weighing and calculation of moisture content, and provides procedures when concentrates are susceptible to oxidation, decomposition or sublimation. Note: ISO 10251:2006 is not applicable to drying samples intended for determination of volatile elements such as mercury or sulfur.
Key topics and technical requirements
- Drying conditions: Test portions are dried at 105 °C ± 5 °C (forced-air oven or inert-gas circulation) and dried to constant mass where possible.
- Test portion size: Minimum 1 kg per test portion; trays should allow sample spread to a thickness
