Lecture 10 resources 1 Flashcards
What economic effect did the war have?
Correlation between world war 1 and the first financial crisis.
therefore economy and mineral resource extraction is linked.
What is driving the demand?
if it cannot be made it is extracted and processed - we need them.
What is in a mobile phone?
+ Arsenic (gallium arsenide in the amplifier and receiver). Mined
in China, Chile, Morocco, Peru, Kazakhstan, Russia, Belgium
+ Copper (circuitry). Mined in Chile, United States, Peru, China, Australia, Russia, Indonesia, Canada, Zambia, Poland, Kazakhstan.
+ Gallium (gallium arsenide). Mined in China, Germany, Kazakhstan and Ukraine.
+ Gold (circuitry). Mined in China, United States, Australia, South
Africa, Peru, Russia, Canada, Uzbekistan, Ghana.
+ Magnesium compounds (phone case). Mined in China, Turkey, North Korea, Russia, Slovakia, Austria, Spain, Australia.
+ Palladium (circuitry). Mined in Russia, South Africa, Canada, United States and Zimbabwe.
+ Platinum (circuitry). Mined in South Africa, Russia, Canada.
+ Silver (circuitry). Mined in Peru, Mexico, China, Australia, Chile, Russia, United States, Poland, Bolivia and Canada.
+ Tungsten (circuitry). Mined in China, Russia, Canada, Austria.
+ A multitude of petroleum products are used in cellular phones. (plastics)
is it easy to recycle from a mobile phone
no, everything is entwined with plastic products = difficult,
what is a circular economy
the idea that be build materials with the idea that we will recycle them round and round again.
what is a circular economy
the idea that be build materials with the idea that we will recycle them round and round again.
does the US take an equal share of the worlds resources
No, the US uses 30% of the worlds resources but makes up 4% of the worlds population.
The club of rome report 1978. limits to growth
the report predicted the catastrophic end to mineral reserves, they failed to understand the dynamic concept of the reserves. as we learn more about geology, new infrastructure and technology then more reserves are discovered even if they are there already.
What’s the difference between a resource and a reserve.
Dynamic concept
Resource: concentration or occurrence of solid material of economic interest in or on the earths crust or where there is reasonable prospect for economic extraction.
The location, quantity, grade (or quality), continuity
and other geological characteristics of a Mineral Resource are known, estimated or interpreted
from specific geological evidence and knowledge, including sampling.
Reserve: economically mineable part of a Measured and/or Indicated Mineral Resource. It includes diluting materials and allowances for losses, which may occur when the material is mined or extracted and is defined by studies at Pre-Feasibility or Feasibility level as appropriate that include application of Modifying Factors. Such studies demonstrate that, at the time of reporting, extraction could reasonably be justified.
What happened to the mined grade of copper between 1880 and 1985
initially the average grade of ore in 1880 (3%)
by 1985 it was at 0.55%
can now mine at lower grade ores - technological advancements.
How does supply keep up with demand.
demand drives price, demand is higher, develop ways of meeting demand by mining lower grade ore due to improved technology.
Problem with electric veichles
resource hungry - use lots of resources - cobalt, copper, lithium.
