Do you believe new technologies for reclaiming mining waste can make industrial metal production cleaner?
Phoenix Tailings, a Boston-based company cofounded in 2019 by Tomás Villalón Jr., has developed a proprietary electrochemical technique to extract rare earth metals from mining waste. This innovative method aims to transform industry byproduct into sustainable materials.
Why it matters
The company seeks to address the significant pollution generated by the mining industry, which produces over several billion tons of waste annually. By recovering metals from these tailings, the process provides an environmentally friendly alternative to traditional extraction.
The company employs a proprietary electrochemical technique to process mining waste. When powered by renewable energy, this extraction method is entirely carbon-free and generates no toxic byproducts.
The players
Tomás Villalón Jr.
He is the cofounder of Phoenix Tailings who grew up in San Antonio and witnessed the environmental impact of industrial pollution in Monterrey, Mexico.
Phoenix Tailings
This Boston-based materials science company specializes in developing sustainable electrochemical processes to recover metals from mining waste.
The details
Founded by San Antonio native Tomás Villalón Jr., the company was inspired by his childhood exposure to pollution in Monterrey, Mexico. Their technology effectively repurposes mining byproduct that would otherwise remain waste, targeting the recovery of rare earth metals.
