Rare Earth Recovery from Mine Tailings

Old tailings piles and mining waste often still hold rare earths and critical minerals that were once written off as unrecoverable. SEM TECH recovers rare earths and 53 of the 60 US critical minerals from tailings while remediating heavy metals at the same time.

What we recover

Rare earth elements alongside a wide span of critical minerals, all from a single leaching solution. The process concentrates the values and cleans heavy metals out of the waste.

Why it fits tailings and legacy sites

• Turns a cleanup liability into a profitable product.
• Remediates heavy metals while it recovers value.
• Closed loop, low cost, and fully domestic.
• Opens up feedstocks where extraction was halted over pollution concerns.
