Skyrocketing demand for copper guarantees to push costs to new heights. As the worldwide economic system transitions away from fossil fuels, it’ll want twice as much copper within the coming years than humanity has mined all through all of its existence.
Still Bright, a New Jersey-based startup based in 2022, thinks it has discovered a novel (and cleaner approach) to slash these prices.
“The truth that we’ve already mined the simply mineable stuff, and the truth that we’d like many extra mines to return into manufacturing yearly — we’re speaking like 60-plus mines — is it looks like an impossibility, like there’s no path to get there,” Randy Allen, co-founder and CEO of Nonetheless Brilliant, instructed TechCrunch.
However a big fraction of that demand could possibly be met if corporations can extract extra copper from the ore they already mine.
Nonetheless Brilliant has developed a brand new strategy to extract copper, one which it says can get well practically all of the copper from typical ores with out pre-processing steps that lose as much as 20% of the steel. It’s efficient sufficient that it might even be used on tailings, the discard piles that also comprise smaller quantities of the steel that mines depart behind.
“Any copper that was misplaced as waste, we will truly course of that and get the copper again,” Allen mentioned.
To spice up manufacturing from single digits to a whole lot of tons per 12 months, Nonetheless Brilliant has raised an $18.7 million seed spherical led by Materials Influence and Breakthrough Power Ventures, the corporate solely instructed TechCrunch. Azolla Ventures, Fortescue, Influence Science Ventures, and SOSV participated.

Nonetheless Brilliant’s expertise permits it to extract copper with out producing dangerous air pollution. The place most corporations primarily burn away undesirable elements of the ore — releasing a lot of it into the ambiance — Nonetheless Brilliant soaks copper-containing ores in a vanadium-based resolution, which attracts the steel out of the ore. When the vanadium resolution is spent, the corporate’s system makes use of electrical energy to regenerate it.
The core expertise was impressed by a kind of long-duration vitality storage often called a “vanadium stream battery.” In it, a vanadium-based resolution that may be saved in massive tanks is charged and discharged by flowing it previous a membrane.
“All of that is type of happenstance. The technical inventor, the CTO of the corporate Jon [Vardner], he was engaged on two totally different tasks,” Allen mentioned, one on vanadium stream batteries and one other on utilizing vanadium to extract copper. “It’s connecting the dots. One individual occurred to be doing each.”
Nonetheless Brilliant’s modular system will have the ability to be put in at mines spanning a variety of sizes. As a result of the vanadium-based course of works so shortly, the corporate’s tools is far smaller than a typical refiner for a similar quantity of copper manufacturing. “The processing is on the order of minutes, as much as an hour. That enables us to maintain every part actually small.”
The small dimension pays monetary dividends, too. Allen mentioned that Nonetheless Brilliant’s tools is 70% to 90% cheaper than typical pyrometallurgical gear. Presently, the corporate’s course of prices about the identical to run as a typical refinery, however Allen expects that to alter. “There’s quite a lot of alternative for us to be cheaper,” he mentioned.
Nonetheless Brilliant is planning to construct an indication unit in 2027 or 2028 that’s able to producing 500 tons of copper yearly. It’s a giant leap from the present pilot scale unit, which makes 2 tons per 12 months. The last word commercial-scale system will produce 10,000 tons per 12 months.
The clock is ticking, although. Nonetheless Brilliant wish to begin refining copper in massive sufficient portions to profit from any tariffs President Trump would possibly impose on imports of the steel. If it does, it might use that income to develop and deploy commercial-scale models.
“We see ourselves as having a path to be among the many most cost-effective copper producers,” Allen mentioned.
