Acid mine drainage (AMD) occurs when sulfide minerals are exposed to an oxidizing environment. Most of the methods for preventing AMD are either short-term or high cost solutions. Coating with iron phosphate is a new technology for the abatement of AMD. It involves treating the sulfide with a coating solution composed of H2O2, KH2PO4, and sodium acetate as a buffer agent. The H2O2 oxidizes the ...

Mineral Mining and Processing Effluent Guidelines. EPA promulgated the Mineral Mining and Processing Effluent Guidelines and Standards ( 40 CFR Part 436) in 1975, and amended the regulation in 1976, 1977, 1978, and 1979. The regulation covers wastewater discharges from mine drainage, mineral processing operations and stormwater runoff.

1. China — The country's phosphate mining production decreased in 2018 to 140 million metric tons (MT) from 144 million MT in 2017, which is likely a result of Beijing's environmental crackdown on the mining industry. There has also been speculation in the past that China's phosphate production in 2017 may have been overstated.
