Critical Need for the Technology
In water, mobile metal ions like copper, silver, cobalt, and nickel cause damage to human health and the environment. In industrial processes involving these ions, significant waste is generated while treating water to remove them prior to discharge.
Meanwhile electronics, electric vehicles, and batteries rely on these same metals as raw materials. The United States rely on imports of the same metals for production of these technologies; in fact, several have been placed on the ‘critical minerals’ list because of the high import reliance and high domestic need.
Harvesting these metals from nontraditional sources satisfies two important needs simultaneously. First, it establishes a domestic supply of currently-imported critical minerals. Second, it remediates problematic water streams more quickly and with less residual waste than competing processes.
- Ion exchange beads: established firms such as DuPont, Purolite, Rohm & Hass, as well as early stage companies such as Periodic Products provide polymer-based ion exchange for use in columns with regeneration.
- Adsorbents: established firms such as Lanxess provide adsorbents like granular ferric oxide and zero valent iron.
- Do nothing: in some geographies, the incumbent approach is to avoid treating metal-bearing water at all.
Treatment market: mining, leach liquor purification, primary metal treatment (pickling), electroplating, semiconductor manufacturing, battery recycling, hazardous site remediation, water reuse.
Raw material markets: batteries, high-temperature alloys, jewelry, electric vehicles, semiconductor manufacturing.
NUMiX Materials harvests critical minerals from contaminated water using geomimetic sorbents.
