Acid mine drainage (AMD) prevention or remediation is a major issue of the environmental management sulfide-bearing active and abandoned mining sites, main sources acidic waters being wastes tailings. The present work intends to check circular economy approach such issues in region Sardinia, where pollution, due AMD, concern. Tests were conducted on basic drainage-producing feldspar that could be recycled as buffering agents Among sites investigated, Furtei epithermal gold deposit tailings are most polluting those can better test agent efficacy. Buffering results show near-neutral conditions attained following steps similar pure calcite buffer. potential waste both buffer content, which provides short-term buffering, enhanced by content provide long-term buffering. Buffered dramatic decrease concentration metals leachate, down meet requirements for discharge industrial according Italian legislation.
