Core Resources, in collaboration with CRU, was engaged by the Queensland Government to conduct a vital study on the supply and demand of sulphuric acid across the North West and North East Minerals Provinces. As Queensland’s mining industry continues to expand, the availability of sulphuric acid is critical to the viability of current and upcoming mineral projects, including those focused on essential battery metals and fertiliser production.

Key Findings from the Study

The report highlights a potential future supply-demand imbalance as existing sources of sulphuric acid, such as the Glencore Mount Isa Copper Smelter, face uncertainty. Glencore’s anticipated closure of its Mount Isa mining operations by mid-2025 could remove 47% of Queensland’s sulphuric acid supply. As demand for sulphuric acid is forecasted to rise with new critical minerals projects, urgent action is needed to develop alternative local production solutions or explore increased imports.

Meeting Future Demand

With demand expected to reach 2.86 Mtpa by 2035, and potentially 5.23 Mtpa under speculative scenarios, the study evaluates two primary options to meet future needs: importing sulphur prill or sulphuric acid via the Port of Townsville or establishing domestic production through pyrite roasting or other innovative solutions.

Core Resources is committed to supporting the development of a robust sulphuric acid supply chain to ensure the continued success of Queensland’s critical mineral projects.
