How much iron has been mined ever?
As of 2021, it is estimated that approximately 2.5 billion metric tons of iron have been mined throughout history. Iron ore is one of the most abundant minerals on Earth and has been extracted for thousands of years for use in various applications, primarily in steel production. The total amount mined continues to grow as global demand for steel remains high. However, precise figures can vary based on different sources and methods of estimation.
What percentage use do diamonds have?
One hundred percent of all diamonds mined are 'used', either as gemstones -- about 20%, or as industrial diamonds.
How many tons of ore contain one ounce of gold?
The grade of the ore from which gold is to be recovered will determine how much of it must be processed to recover that ounce of gold. There is a broad variation, but there is plenty of gold in ores that is dispersed so widely that it is not economical to attempt commercial recovery. In an additional note, gold exists in veins within ores, and is not chemically combined with other elements within that ore. Mines that are probably considered marginal yield something on the order of 4 to 6 grams of gold per ton of ore, and you can do some simple math from there (perhaps using 5 grams/ton) to discover an answer for the stated grade of ore. There are just over 30 grams in a Troy ounce, and at 5 grams/ton, you're looking at 30 divided by 5 or 6 tons of ore to recover that (Troy) ounce of gold from ore with a grade of 5 grams/ton. If you have 6 tons of ore, that's a lot of ore, and you have a lot of hard work ahead of you if want the ounce of gold disbursed in it. It will take time and energy to win the metal, and it might be as cheap to buy the gold as to recover it from the ore. But we'll leave it for you to do the math after you get an assay.

Once all the loose gold has been mined from streams who moved into the mining towns?
Well, one answer is saloons- to remove the gold from the miners! However, once the easy placer gold was mined from the streams, mining companies that sought to mine the rock that the placer gold came from moved in, and began mining gold ore that required processing to extract the gold.
How much of ore needs to be mined to get 2500 tons of gold?
To determine how much ore needs to be mined to obtain 2,500 tons of gold, one must consider the gold concentration in the ore, typically expressed in grams per ton. For example, if the ore contains 5 grams of gold per ton, approximately 1,250,000 tons of ore would need to be mined (since 2,500 tons of gold equals 2,500,000 grams). The exact amount will vary significantly based on the grade of the ore being mined.
How much gold do miners find in one day?
Gold miners never found a set amount a day. The amounts changed based on location, weather, and how much had been mined prior.

What is the most common rock that is mined using a quarry?

Can the map of an ore deposit help miners decide how to mine the ore?
Yes, because if one does not map out where the ore is, much waste rock will be mined and that's a big waste of money.
How much gold produced in one rock?
It depends on the rock, one rock could have alot of gold while another may have no gold at all. I suggest you ask the question again and be more specific such as telling what type of rock, where, climate, and history of the area. GOOD LUCK!
How much does gold ore sell for on Rock Isle on HorseIsle?

What are the advantages and drawbacks of using gold standard?
Unfortunately there are disadvantages to the gold standard. One of the main disadvantages of implementation is that a gold standard would artificially inflate gold's value, increasing the cost of items and industrial process in which it is used. Another disadvantage is under the gold standard, gold mined at a different rate than the economy grows can produce both inflation, when deposits are discovered and extracted and deflation when they are mined to exhaustion
What type of rock is gold in?
gold does not form in a rock. however it does forms along igneous rock and quarts veins. For gold to be present one of these two rocks will more then likely be there as well. (In some large gold nuggets, pieces of quarts will be stuck to the gold)
Is diamond a polished rock?
