“Utilizing Silicon Wafers to Recover Essential Minerals from Mining Byproducts with SiTration”
Brendan Smith didn’t intend to be in the critical minerals business.
But Smith and Grossman’s company, SiTration, has a different proposal: use its equipment to treat the wastewater and harvest more minerals in the process.
To turn the wafers into filters, Smith and Grossman tweaked an existing chemical treatment to etch minute pores in them.
For a larger mining site, the company would use about as much silicon as a medium-size solar farm, Smith said.
Although SiTration is starting with mining waste, including a pilot project with Rio Tinto, it’s also pitching its filtration systems to battery recyclers and metal refiners.
