SiTration provides silicon electro‑extraction (SEE) and silicon nano‑filtration (SNF) technologies that recover critical metals and minerals from mining waste, leachate, and recycled streams using only electricity and no added chemicals. The modular, fully electric process converts low‑grade or complex aqueous waste into market‑grade rare‑earth element concentrates, LME‑grade copper, and precious metals, reducing capital and operating costs while eliminating hazardous reagents. This enables mining operators, mineral processors, and recyclers to monetize waste streams and strengthen critical mineral supply chains.

Problem
Conventional mining and metal recovery processes rely on costly chemical and thermal treatments, generate large volumes of waste, and are unable to extract valuable minerals from low‑grade or complex waste streams, leaving critical resources untapped.
Solution
SiTration applies patented silicon electro‑extraction (SEE) and silicon nano‑filtration (SNF) technologies to directly recover critical metals and minerals from mining waste, leachate, and recycled streams. The process uses durable silicon electrodes and anti‑fouling silicon membranes, requiring only electricity and no added chemicals, which reduces capital and operating costs while eliminating hazardous reagents. By targeting dilute and complex aqueous streams, SiTration can produce high‑purity outputs such as rare‑earth element concentrates, LME‑grade copper, and precious metals. The modular, scalable system simplifies flow sheets, creates new revenue streams from previously discarded material, and strengthens supply chains for energy‑critical minerals.
Target Audience
Primary customers are mining operators, mineral processors, and recycling firms seeking to monetize waste streams and secure domestic supplies of critical minerals.
