NEUTRALISING MINERAL REACTIONS IN ACID MINE DRAINAGE CONTROL

酸性矿山排水控制中的中和矿物反应。该项目旨在解决采矿业废石堆和尾矿库中的铁硫化物释放酸和有毒元素的严重环境问题。长期的中和能力，目前还没有在实验室评估中测试，可从一些硅酸盐和铝硅酸盐矿物的反应中获得。这一潜力尚未得到系统的测试或模拟。该研究项目旨在了解矿物分层和混合组合长期缓解酸生产的相对机制和速率。提高认识将为酸性矿山废水的评估和控制提供方法。

NEUTRALISING MINERAL REACTIONS IN ACID MINE DRAINAGE CONTROL. The project addresses the serious environmental problem of acid and toxic element release from iron sulfides in waste rock dumps and tailings storage in the mining industry. Long-term neutralising capacity, currently not tested in laboratory assessments, is available from the reaction of some silicate and aluminosilicate minerals. This potential has not been systematically tested or modelled. The research project aims to understand the relative mechanisms and rates for long-term alleviation of acid production with mineral layered and blended combinations. Improved understanding will provide methodology for assessment and control of acid mine drainage.
