Giraffe Bio aims its bespoke biomolecules at the looming copper shortage

Giraffe Bio, a critical minerals startup, aims to address the looming copper shortage by developing mineral-specific chemicals to enhance copper recovery from existing mines. The burgeoning demand for copper due to AI data centers and electrification could result in a 25% gap between supply and demand by 2040. Traditional mining methods, which primarily involve opening new mines, are costly and have low success rates, with only 0.3% of prospective mines bearing fruit.

Giraffe Bio's approach, however, focuses on biotechnology to maximize copper extraction from existing mines, particularly during the heap leaching process where microbes help separate minerals from waste. By engineering compounds specific to each mine's mineral content, Giraffe Bio claims to extract up to 5% more copper, a significant improvement from the typical 1% to 2% gain.

The startup recently secured a $6.4 million seed round led by Orion Industrial Ventures, alongside investment from BHP Ventures, Twynam, Air Capital, and Baruch Future Ventures. Giraffe Bio's technology can be adapted to other minerals like gold and silver, as the platform is versatile. The compounds are integrated into the mine's flotation process, where chemicals facilitate the separation of minerals in a water bath.

By binding more tightly to the desired minerals, Giraffe Bio's chemicals enable the recovery of a higher proportion of copper. Additionally, the company is developing depressors to replace harmful chemicals in the flotation process, reducing environmental impact and maximizing output.
