Question

write a note on how gold extraction lead to climate change​

Answer 1

During these ancient times, gold was mined from alluvial placers—that is, particles of elemental gold found in river sands. The gold was concentrated by washing away the lighter river sands with water, leaving behind the dense gold particles, which could then be further concentrated by melting.

Mining is responsible for 4-7% of global GHG emissions.

Answer 2

Answer:

Hope it helps u

Explanation:

Gold is valuable and rare. Large amounts of rock need to be mined and processed to produce an ounce of gold and this uses significant amounts of energy. This energy use and associated greenhouse gas (GHG) emissions are higher per tonne of gold than for the equivalent volume of metals produced in bulk.  But, on a value basis, gold’s GHG emissions intensity is relatively low. And total emissions from the gold industry are relatively small.
