As one of leaders of machines required in mining of rare earth industry, SBM always seeks innovation & excellence.
Mining rare earth metals is quite different from other kinds of mining. One rare-earth mine produces many kinds of elements, but there are many processes involved and all these processes contribute to pollution. The generation of Thorium, a radioactive element leads to leukemia when it leaches into drinking water. Workers have to extract rare earth metals manually from the ore which increases ...

And rare earth mining, whether legal or not, entails shocking environmental costs. Research has found that producing one tonne of rare earth ore (in terms of rare earth oxides) produces 200 cubic metres of acidic waste water. The production of the rare earths needed to meet China's demand for wind turbines up to 2050 (in a scenario of radical wind power expansion) will result in the release ...

04.12.2019· Rare earths are traded on the NYSE in the form of exchange-traded funds (ETFs) that represent a basket of supplier and mining stocks, as opposed to trading in the metals themselves. This is due to their rarity and price, as well as their almost strictly industrial consumption. Rare earth metals are not considered a good physical investment like precious metals, which hold low-tech intrinsic value.

Rare earth elements, used in all manner of tech machines, including green ones, have rare properties but are much more abundant than gold. However, the physical chemistry of rare earths makes them difficult and energy-intensive to refine. It takes about twice as much energy to get access to and refine a pound of rare earth as a pound of lead, for example.

Rare earth mining can be open pit, underground or leached in-situ. For a typical open pit mine, the approach is very similar to other mining operations which involve removal of overburden, mining, milling, crushing and grinding, separation or concentration. The product of the enriched concentrate after separation may contain around 30%–70% of rare earth bearing ore. The process requires ...
