Innovation potential along the phosphorus supply chain: A micro and macro perspective on the mining phase

Area of Science:

• Environmental Science
• Geochemistry
• Resource Management

Background:

• Phosphorus is essential for all life, non-substitutable, and finite.
• Current linear supply chains lead to losses and environmental impacts like eutrophication.
• Sustainable phosphorus utilization requires multidimensional innovations across the supply chain.

Purpose of the Study:

• To identify innovation potential in phosphate-rock mining (extraction and beneficiation).
• To analyze strategies for improving P2O5 recovery, waste utilization, and by-product recovery.
• To provide an economic breakdown of production costs for diverse global phosphate mines.

Main Methods:

• Analysis of innovation potential in mining processes.
• Macro-level strategy development for sustainable phosphorus management.
• Economic breakdown of production costs using primary data from 85 phosphate-rock mines.

Main Results:

• Significant differences in production costs exist between igneous and sedimentary deposits.
• Mining methods (underground vs. open-pit) and deposit types influence cost structures.
• No universal solution exists for phosphate-rock mining challenges due to geological variations.

Conclusions:

• Optimizing phosphorus recovery and utilization in mining is vital for sustainability.
• Economic viability of phosphate mining is highly dependent on deposit type and extraction method.
• Tailored, site-specific strategies are necessary for efficient and sustainable phosphate-rock mining.
