After the spill leaked millions of hazardous mine waste into the river system, this was it later that day.

在泄漏将数百万危险的矿山废物泄漏到河流系统之后，当天晚些时候就是这样。

So, mine waste material is potentially a really great source of material that could be repurposed for enhanced rock weathering, and I think that's really good because it creates a circular economy.

所以，矿石废料有可能是一种不错的材料来源，可以做改动用于加速岩石风化，我认为这做法很好，因为它会促进循环经济的产生。
