Global iron ore production growth will accelerate in the coming years, bringing an end to the stagnation that has persisted since iron ore prices hit a decade-low average of USD55.0/tonne in 2015. We forecast global mine output growth to average 2.7% over 2022-2026 compared to -1.3% over the previous five years.

7.4.3: Solution Mining. Solution mining is the extraction of the ore through a dissolution process, i.e., we pump a solvent through the ore, the solvent dissolves the constituent of interest, and then we recover and process the resulting liquid, which is known as the solute or pregnant liquor.We can apply this method to in-situ deposits using a borehole mining …
