types of mining
Which mining is used to mine ores 50 m or below earth's surface?
subsurface mining
explain noise pollution
(the effects)
noise pollution- can cause physical damage to organisms and structures (is loud)
why lithium? (list a reason)
anything along these lines are correct:
1. lightest metal on the periodic table
2. unique ability to store high amounts of energy in a small space (high energy density)
3. can be recharged thousands of times
what is reclamation?
the act (process) of returning land back to its original state after mining.
what type of mining is used to remove the overburden?
surface mining
explain air pollution
(the effects)
air pollution- can release hazardous pollutants into the atmosphere (is bad)
what metal has been nicknamed white gold?
lithum
what is brine?
salt water rich in nutrients, rich in lithum
What type of surface mining is it when digging a huge hole in the ground to collect ores?
Open pit mining
explain displacement of wildlife
(the effects)
animals leave their area if their habitat is destroyed, and can be replaced by invasive species.
(animals have no home = bad)
list a reason for increased lithium demand
anything along these lines are correct:
1. global shift to EVs
2. renewable energy storage
3. consumer electronics
4. water scarcity
5. economic growth in mining hubs
6. global CO2 reduction
what is water?
liquid, made of hydrogen and oxygen. organisms need water to survive.
What type of subsurface mining is it when hot water is pumped into ore and compressed air lifts it to the surface?
Solution mining
explain water contamination
(effects)
the act of water that seeps through mines and/or through piles of rock can pick up toxic chemicals.
which lithium extraction method produces the least CO2?
Geothermal brine (DLE)
what is the most destructive mining method?
open pit mining
What type of surface mining is it when streams transport mineral grains to the steam bed where they concentrate?
Placer mining
explain collapse
(hint= abandoned mines)
sinkholes that swallow up houses and buildings that are built on top of abandoned mines.
which lithium extraction method produces the most CO2?
Spodumene (hard rock mining)
what is mining?
the act of digging for materials and resources
