The process of mining REEs is ecologically devastating. Processing one ton of rare earth metals releases 2,000 tons of radioactive materials, carcinogens, toxic compounds, acids, and other pollutants into the environment. Since thorium and uranium often occur alongside REEs in nature, tailings from mines tend to be radioactive.

How the process of mining for silver works - Fraimed

The process is attributed to a mining specialist – Bartolomé de Medina who was the first to use a silver amalgamation with mercury to extract silver. De Medina' s technique involved mixing the ore with mercury and strong brine. This formed a mercury silver amalgam from which semi-pure silver could be obtained by distilling off the mercury.

That's because mining and refining processes have improved over many centuries. In fact, silver is one of the earliest metals documented in history, discovered in nugget form around 4000 BC.

Rare Earths - Department for Energy and Mining

Rare earths were named by Johann Gadolin in 1794 for a group of chemically similar, metallic elements with atomic numbers 57 through to 71. In order, these are lanthanum (La), cerium (Ce), praseodymium (Pr), neodymium (Nd), promethium (Pm), samarium (Sm), europium (Eu), gadolinium (Gd), terbium (Tb), dysprosium (Dy), holmium (Ho), erbium (Er), thulium (Tm), ytterbium (Yb) and lutetium (Lu).

Potential dangers of mining rare earth metals
