Sustainability in Mineral Supply
- 4 things to know
- Component 2
Overview
Recall questions on finite reserves, energy-intensive mining, land rehabilitation, trade and price instability, the energy use, waste, smelting pollution and water use of ore processing, and recycling, substitution, extraction efficiency and circular economy approaches.
What you need to know
Answer each one before you reveal it.
Why is water usage a sustainability concern in ore processing?
What is meant by substitution as a strategy for mineral sustainability?
How can improved extraction efficiency enhance mineral sustainability?
Questions from this subtopic
Each one with the model answer underneath.
- 1
Why is the finite nature of mineral reserves a sustainability issue?
Model answer
Ores are non-renewable; continued extraction depletes reserves, threatening long-term supply and requiring alternatives.
- 2
How does the energy intensity of mining create sustainability challenges?
Model answer
Extraction and processing consume large amounts of energy, often from fossil fuels, contributing to carbon emissions and resource depletion.
- 3
What challenges are associated with land rehabilitation after mining?
Model answer
Restoring ecosystems, stabilising landforms, and removing contamination are costly, technically difficult, and often incomplete.
- 4
Identify two sustainability issues associated with the international trade of mineral ores.
Model answer
The carbon footprint of long-distance transport and dependency relationships between producing and consuming nations.
- 5
How does price instability affect producer economies reliant on ore exports?
Model answer
Volatile prices cause unpredictable revenues, hindering economic planning and potentially causing boom-bust cycles.
- 6
Why is energy consumption a sustainability issue in ore processing?
Model answer
Smelting and refining require high energy inputs, often from fossil fuels, increasing carbon emissions.
