The assuming demand for copper guarantees to exceed prices to recent heights. When the global economy leaves fossil fuels, it can need twice as many copper In the coming years than humanity, it brought out throughout its existence.
Still Bright, a startup with New Jersey, founded in 2022, believes that he found a recent (and cleaner way) to reduce these costs.
“The fact that we have already extracted easy-to-bring things, and the fact that we need many more mines to enter the production of each year-we say about 60 mines-it seems that it is impossible, as if it was not expensive to get there”, Randy Allen, co-founder and general director of the general director. Still clearTechcrunch said.
But a large fraction of this demand may be satisfied if corporations can extract more copper from ore, which they are already extracting.
Still Bright has developed a recent way of separating copper, which, he says, can get better just about all copper from typical ores without pre -processing stages that lose to 20% of metal. It is effective enough so that it could possibly even be used on waste, rejected piles, which still contain smaller amounts of metal, which the mines leave behind.
“Every copper that has been lost as a waste, we can process it and recover copper,” said Allen.
To increase production from individual numbers to lots of of tons per 12 months, Still Bright collected a $ 18.7 million round of seeds run by Material Impact and Breakthrough Energy Ventures, the company said only TechCrunch. Apollo Ventures, Fortescue, Impact Science Ventures and SOSV.

Bright technology allows it to extract copper without causing harmful pollution. Where most corporations burn the unwanted parts of Rudy-connecting it in the atmosphere-immerses the rud containing copper in a vanadium-based solution, which pulls metal from ore. When a vanadium solution is released, the company’s system uses electricity to regenerate.
The basic technology has been inspired by the form of energy storage with a long period often called the vanadium flow battery. In it, a solution based on vanadium, which may be stored in large tanks, is charged and unloaded by swimming next to the membrane.
“All this is such an event. Technical inventor, CTO from Jon [Vardner]He worked on two different projects – said Allen, one of the vanado batteries and the other using a copper vanadium. “It connects dots. One person did each.”
The modular Bright system will find a way to be installed in mines covering the range of sizes. Because the process based on the vanadium works so quickly, the company’s equipment is much smaller than a typical refiner for the same copper production. “Processing is in order of a minute, to an hour. It allows us to keep everything really small.”
The small size also pays financial dividends. Allen said that Bright equipment is 70% to 90% cheaper than typical pyrometalurgical equipment. Currently, the company’s process costs more or less the same as a typical refinery, but Allen expects it to change. “There are many opportunities to be cheaper,” he said.
Still Bright plans to build a demonstration unit in 2027 or 2028, which is able to produce 500 tons of copper per 12 months. This is a big jump from the current pilot unit, which produces two tones a 12 months. The final business scale system will produce 10,000 tons per 12 months.
However, the clock is ticking. Bright would still like to start copper refining in enough large quantities to use all tariffs that President Trump can impose on the import of metal. If so, it could possibly use these revenues to develop and implement business scale units.
“We see ourselves as a path of being among the cheapest copper producers,” said Allen.
