Tailings, alkaline mine wastes generated by diamond mining are reactive with carbon dioxide, a keygreenhouse gas. Initial analyses indicate that overall CO2 sequestration capacity of diamond mines is orders ofmagnitude greater than the anticipated greenhouse gas emissions, but the accessible proportion will depend ontailings management. For instance, reacting mine wastes with CO2-rich gas streams such as from an on-sitepower plant can accelerate carbon sequestration. Research is needed to assess the reactivity of the mine wasteswith CO2 to determine the optimal strategies for sequestering CO2. This research offers potentially significanteconomic and environmental benefits to mine operations.

钻石开采产生的尾矿、碱性矿山废物与二氧化碳（一种关键的温室气体）反应。初步分析表明，钻石矿的二氧化碳总固存能力比预期的温室气体排放量大几个数量级，但可获得的比例将取决于尾矿管理。例如，将矿山废物与富含二氧化碳的气流（如来自现场发电厂的气流）反应可以加速碳固存。需要进行研究，以评估矿山废物与CO2的反应性，从而确定封存CO2的最佳策略。这项研究提供了潜在的显着的经济和环境效益的矿山作业。
