Peak minerals Flashcards
What is the definition of peak minerals?
Peak minerals are when the maximum rate of extraction of a mineral resource is reached
What is the difference between Peak minerals and Peak Oil?
Oil cannot be recycled while minerals and metals can
What are Reserves?
Mineral deposits that are economically feasible to extract at current market prices and with existing technology
What factors influence whether a mineral deposit is considered a reserve?
Grade and Price
What impact does fracking had on Peak Oil predictions?
Led to a rebound in US oil production, challenging the initial accuracy of Hubbert’s Peak Oil predictions
What is the trend in gold grade?
Gold grade is decreasing
Is there a potential for a Peak in Phosphate production?
Some studies suggest that a peak in phosphate production could occur in the coming decades. However, the discovery of new reserves, like those in Morocco, can offset this peak.
What are the environmental concerns related to Phosphate?
Excess phosphorus from fertilizers can lead to eutrophication in lakes and coastal areas, causing algal blooms and oxygen depletion
What are potential solutions to address Phosphate related challenges?
- Recycling phosphorus from waste products
- Improving efficiency in phosphorus production and use
- Exploring alternative agricultural practices
What are the three main types of lithium deposits?
- Pegmatite deposits and related metasomatic rocks
- Lithium-rich hectorite clays from volcanic deposits - Salar evaporites and geothermal deposits.
How has Lithium use changed over time?
Increased, especially with the the rise of rechargeable batteries
Are long term lithium shortages predicted?
No
Is copper production nearing a peak?
No
What is the importance of recycling in the context of mineral resource?
Recycling plays a crucial role in mitigating resource depletion. Increased recycling can significantly reduce the need for primary mineral extraction.
What are the key arguments made by Ragnarsdottir & Sverdrup (2015) regarding resource limits?
- World is approaching its resource limits
- Resource-backed economic growth is unsustainable
- Advocate for systemic recycling
