Biomining Rare-Earth Elements | Earth and Atmospheric Sciences

Mutant bacteria. Monazite is one of the ores known to contain rare earths in sufficient quantities to be worth mining. Schmitz can't just throw a chunk of monazite and some bacteria into a beaker and wait to see what happens. Rather, the initial screening for genes that may be related to leaching of rare earths will happen in microplates that ...
