Validation and standardisation of sequential leaching tests to better predict the impact of mining on ground and surface water quality
Total Grant Value
This project proposed to investigate the potential use of sequential leaching methodologies to identify iron ore waste rock-metal/metalloid risk factors which can be used to inform and prioritise long-term and expensive kinetic testing and subsequent investigations as required.
The main aim of this investigation was to research, develop and validate sequential leaching methodologies as a tool to better identify potential contamination risks to ground and surface water quality.
A sequential leaching procedure was developed and optimised to meet the requirements for assessing potentially problematic mine waste produced by iron ore mining activities, focusing on those that have low sulphur concentration and /or are of complex mineralogy.
Keywords: sequential leaching, iron ore, acid mine drainage, metal leachate
