Microbial extraction and low-grade ore recovery reshape sustainable copper production through 2036

Industry Overview

The global copper bioleaching market was valued at approximately USD 4.8 billion in 2025 and is estimated to reach USD 5.2 billion in 2026, reflecting a growth rate of 8.3%. Growth is being driven by declining copper ore grades, increasing demand for copper from electric vehicles, renewable energy, power grids, and data centers, and the need for lower-cost and lower-emission extraction methods. Copper bioleaching uses microorganisms to facilitate the oxidation and dissolution of sulfide minerals, enabling copper recovery from low-grade ores, mine waste, and tailings. Heap, dump, and emerging in-situ bioleaching approaches are gaining attention as mining companies seek to improve resource utilization while reducing energy and processing requirements. 

Industry Insights: Scale, Segments, and Shifts
