EN 14899 Waste Characterization Sampling for Tailings Testing

The European standard EN 14899:2005 provides a comprehensive framework for the sampling and characterization of waste from mining operations, specifically targeting tailings. This standard is crucial for ensuring that all relevant parameters are accurately measured to provide an accurate representation of the waste characteristics.

Tailings management in mining involves handling large volumes of materials resulting from ore processing. These materials contain valuable minerals along with by-products and impurities. Proper characterization ensures safe disposal, meets regulatory requirements, and supports sustainable practices.

The standard covers various aspects including:

Sampling strategies
Sample preparation
Analysis methods for physical properties
Analytical techniques for chemical composition
Documentation and reporting of results

Key Parameters Measured:

Parameter	Description
Density	Metric for the mass per unit volume of tailings.
Solid Content (%)	The proportion of solid matter in the tailings relative to total weight.
Settling Velocity (mm/s)	The rate at which particles settle due to gravity.
Grain Size Distribution	Range of particle sizes present, indicating composition and potential for further processing.

Sampling Techniques:

The standard specifies several methods for sampling tailings to ensure a representative sample. These include:

Continuous sampling over time intervals
Point sampling at different depths and locations within the storage facility
Compositional analysis of individual components

Sample Preparation:

Preparation involves drying, grinding, and sieving to achieve a consistent particle size suitable for further testing. This step is critical to ensure accurate measurements.

Analysis Methods:

Physical properties are determined using equipment such as sedimentation tubes and grain size analyzers. Chemical analysis employs techniques like ICP-MS, XRF spectrometry, and pH meters.

The standard emphasizes the importance of maintaining chain-of-custody documentation throughout the process to ensure traceability and compliance with regulatory requirements.
