Why is silver mining costs 5.25 dollar per ounce and the market price 27 dollars?
Because the mining cost is not $5 an ounce. Silver is not profitable to mine by itself. It comes up as a secondary product of existing mines for other metals. To mine for silver alone would cost around $50-$100 an ounce. It is only ten times more plentiful than gold. Does it really make sense to you that gold would cost $500-$900 an ounce to mine and silver only $5? The reason we are running out is because all we get is table scraps from mines for other things.
Why is mining called a killer industry?
The impacts of mining on the health of the miners and the environment are: i. The dust and noxious fumes inhaled by miners make them vulnerable to
pulmonary diseases.
ii. The risk of collapsing mine roofs, inundation and fires in coalmines are a
constant threat to miners.
iii. The water sources in the region get contaminated due to mining.
iv. Dumping of waste and slurry leads to degradation of land, soil, and increase in
stream and river pollution.
that is why it is called killer industry
What is the value of a historic Colorado mining 999 pure silver coin?
The value of a historic Colorado mining 999 pure silver coin can vary based on factors such as its condition, rarity, and demand among collectors. You may want to research similar coins that have been sold recently to get an idea of its potential value. It's recommended to consult with a numismatic expert or coin dealer for a more accurate appraisal.

What state has the most coal mines?
In 2009 Wyoming was the largest producer of coal with 428 million tons produced. West Virginia was second with 139 million tons produced.
The depth of the mine can be calculated using the formula: distance = 0.5 * acceleration due to gravity * time^2. Given that the time taken for the stone to hit the bottom is 3 seconds, we can substitute this into the formula along with the acceleration due to gravity (9.8 m/s^2) to calculate the depth of the mine. The depth of the mine would be approximately 44.1 meters.

Why would it be profitable to reopen copper mines to mine ore that's just 0.5 percent copper?
A low grade copper mine might be re-opened if:
1) If copper prices go up.
2) It's a massive deposit, easily extracted, close to rail lines or shipping.
3) If it's found with something else, like silver or gold, that boosts the value.
4) During war, or major copper shortage.
5) If cheap new refining methods are discovered.
