Panama's ongoing protests about the open pit copper mining has me asking questions about the mining operation. Prior to this protest, I'd never heard the term "open pit mining" before, so I wanted to delve into this so we could all understand together.
Copper is used in a variety of industries, including construction and renewable energy. As renewable energy is gaining traction, we can expect the demand for copper to increase exponentially.
What Is Open Pit Mining
Open pit mining is a surface mining technique used to extract minerals or other geological materials from the Earth. It involves the excavation of an open pit or "borrow" that extends deeper into the ground as the extraction process progresses. This method is commonly employed for extracting minerals such as coal, copper, gold, and iron.
Process
Environmental Considerations
While open pit mining is an efficient method for resource extraction, it raises environmental concerns. Here are some factors to consider:
Environmental Safety
The environmental safety of open pit mining depends on various factors, including the type of minerals being extracted, the location, and the implementation of effective environmental management practices. Regulatory frameworks and technological advancements play crucial roles in mitigating environmental impacts.
Financial Impact
Panama's copper mine, Minera Panama, is majority-owned by Canadian company First Quantum Minerals. They have invested over $6 billion in Panama, which makes them the largest private investor in Panama. Their mining operations begin in 2019. The $375 million they are contractually obligated to pay each year accounts for about 3.5% of Panama's GDP.
Mine Size
At the time of this writing, Panama's copper mine is the 16th largest open pit copper mine in the world, as ranked by production. It accounts for about 1.5% of all copper production.
Conclusion:
Open pit mining is a widely used method for resource extraction, but its environmental impact necessitates responsible management practices. As technology and environmental awareness evolve, the industry strives to strike a balance between meeting resource demands and minimizing ecological consequences.

This method is commonly employed for extracting minerals such as coal, copper, gold, and iron.
Process
- Exploration: The process begins with geological surveys to identify areas with valuable deposits.
- Site Preparation: Vegetation and topsoil are removed to expose the ore.
- Extraction: Heavy machinery, like excavators and haul trucks, is used to remove the ore from the pit.
- Processing: The extracted material is processed to separate valuable minerals from the surrounding rock.
- Reclamation: After extraction, efforts are made to restore the landscape to a state resembling its original condition.
Environmental Considerations
While open pit mining is an efficient method for resource extraction, it raises environmental concerns. Here are some factors to consider:
- Land Disruption: Large areas of land are cleared, impacting ecosystems and biodiversity.
- Water Usage and Contamination: Mining operations often require significant water usage, potentially leading to water scarcity and contamination.
- Air and Noise Pollution: Heavy machinery and blasting contribute to air and noise pollution.
- Waste Generation: The extraction process generates considerable waste, including overburden and tailings, which can pose environmental risks.
