Recycling and Reuse of Mine Tailings. This entry is adapted from the peer-reviewed paper 10.3390/geosciences12090319. Mining is an important industry, accounting for 6.9% of global GDP. However, global development promotes accelerated demand, resulting in the accumulation of hazardous waste in land, sea, and air environments.
