At EESI, we are well-versed in the intricacies of ore and waste characterisation. We provide comprehensive characterisation services that help you identify and categorise waste materials, minimising the risks associated with misidentification.
Our geologists, geochemists, and geophysicists are experienced in the development of baseline characterisation plans and have the necessary tools to conduct kinetic testing to accurately predict acid mine drainage.
Why accuracy matters
Accurate characterisation of ore and waste is essential for successful metalliferous, coal, and industrial minerals operations. When it comes to these types of mines, identifying waste rock accurately and sufficiently is key for the metallurgical and approval processes, as well as the mine’s lifetime profitability.
Incorrect identification can lead to serious operational problems, or even approval withdrawal further down the line. To ensure project success, characterisation of ore and waste should begin during drilling. It is important to begin the process early, with the help of professionals who are familiar with waste geochemistry and geophysics. This will help to ensure that the resource is appropriately addressed and provide a solid basis for the mine’s lifetime profitability.
Lasting, sustainable solutions for you
A minimum of two steps are involved in the process of characterising waste; assessment and analysis. The assessment step involves determining the composition of the waste and the level of hazard it poses to people and the environment. This includes testing the waste for physical, chemical, or biological properties, such as pH, toxicity, and presence of pathogens.
In some cases, kinetic testing to predict acid mine drainage might be necessary, which shows an acceleration of natural oxidation rates over those observed in the field. This type of testing should be conducted early in the baseline characterisation process to prevent any hindrance to the approval program.
The subsequent analysis step involves assessing the waste to determine if it can be recycled or reused. This includes determining the best disposal method for the waste and the potential for reuse or recovery.
