# Copper Bioleaching Microbes Endolith Trains Microbial Blends for Carlota Mine Heaps By Amy Duong | Written with AI assistance | Published 2026-10-20 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/copper-bioleaching-microbes References: [energyconnects](https://www.energyconnects.com/news/utilities/2026/october/startups-are-extracting-more-copper-using-microbes)  Endolith is bringing trained bioleaching microbes to Arizona's Carlota Mine, where KGHM will use them to pull extra copper from aging heap-leach piles while using less sulfuric acid. The Denver startup grows the acid-tolerant organisms in [onsite bioreactors](https://www.trendhunter.com/trends/cultured-wood-production) and feeds them into the leaching system, where they free copper by breaking down iron and sulfur compounds. The approach goes beyond older bioleaching methods by using [mixed microbial communities](https://www.trendhunter.com/trends/generare) rather than a single strain, then changing the blend as heat and acidity shift inside each heap. Endolith targets at least 10% additional copper recovery from low-grade ore, a gain aimed at mines already running below peak output. A 10% lift from low-grade ore makes this a life-extension tool for mining operators that cannot wait years for a new copper project. Onsite monitoring turns bioleaching from a set-and-forget treatment into a managed process, widening where microbial extraction fits across older mine assets.
