Acid neutralization and metal release by calcium-rich feldspar dissolution in mine waste

虽然矿物是自然风化的，但在采矿活动中，这一过程可以显著加快。AS 岩石中含有含硫矿物，风化后可产生酸性富含金属的径流。这表示一个 在下游水质、水生植物的生长和繁殖以及 动物以及潜在的下游腐蚀。碳酸盐岩一旦存在，就会产生酸性。 中和，限制含硫矿物的下游影响。然而，在低硫，低 碳酸盐体系、含富钙长石的岩石在确定矿山废渣中起着重要作用。 径流化学。需要进一步的研究来研究这种物质的中和潜力和金属释放。 矿物。这项研究提供了将新开发的实验能力应用于 不列颠哥伦比亚省大学提出了这个问题。同时，它可能会为SRK咨询公司提供更快的 和更具成本效益的方法来进行动力学测试，提供了相对于其他竞争对手的竞争优势 在他们的领域里。

Although minerals weather naturally, this process can be significantly accelerated during mining activities. As rocks containing sulfur-bearing minerals weather, acidic metal-rich runoff can be produced. This represents a significant concern in terms of downstream water quality, the growth and reproduction of aquatic plants and animals as well as potential downstream corrosion. When present, carbonate rocks contribute to acid neutralization, limiting the downstream impact of sulfur-bearing minerals. However, in low sulfur, low carbonate systems, rocks containing calcium-rich feldspar play an important role in determining mine waste runoff chemistry. Further research is needed to study the neutralization potential and metal release from such minerals. This research offers the possibility to apply newly developed experimental capabilities at the University of British Columbia to this problem. In parallel, it potentially provides SRK Consulting with a faster and more cost-effective approach to carry out kinetic tests, providing a competitive edge over other competitors in their field.
