PRECISION SEPARATION OF CRITICAL METALS
Metals are the Building Blocks of the Global Economy
Sunchem’s patented technologies recover 99% of metals from waste, concentrates, and ore. Our process is low cost, highly selective, and is the only sustainable solution available. Compared to smelting or cyanide leaching, we use less energy and milder chemical conditions to yield 99% pure metal.
Today, we can recover gold, copper, silver, and silicon at our facility in Berkeley, CA.
We are continually seeking new partners and electronic waste and scrap suppliers.
There are billions of dollars worth of critical and precious metals locked in global waste streams every year. We’re on a mission to recover that value.
