They dig it or use some simple machine to dig it out.
Copper was one of the first metals to be discovered, possibly by anchient potters whose furnaces were hot enough to produce copper from the ore malachite.
i do know gold has been around forever and people are always trying to find it. and it's valuable and shiny. but thats it. sorry
Working in an ancient Greek silver mine was unpleasant at best. Ore was extracted by hand, with hammers, by the light of candles, with bad air and extremely hazardous conditions, deep underground. The miner's lives were much like that of Michael Jackson - short, brutish, and nasty.
Having learned iron ore smelting from the Assyrians, the Kushites made iron weapons and tools. Kush then provided iron products, ivory, gold, ebony, and slaves from central and eastern africa to the roman empire, arabia, and india. In return the Kushites received luxury goods from india and arabia.
Yes, The cultural achievement for which the Hittites are best known is the development of iron technology. Iron is a metal that is extracted from ore. The Anatolia region is rich in iron ore. The Hittites used this natural resource to make tools and weapons. Iron was superior to the bronze that was used by other cultures because it was much stronger and more durable.
Gold is typically extracted from gold ore through a process known as cyanidation, where cyanide solution is applied to the crushed ore. The cyanide solution helps dissolve the gold, which is then separated from the ore using processes such as carbon adsorption or zinc precipitation. Finally, the extracted gold is further refined to achieve high purity levels.

Gold is extracted from gold ore through a process called cyanidation, which involves the use of cyanide solution to dissolve the gold from the ore. The dissolved gold is then separated and purified through various refining processes to yield pure gold.

Gold is typically extracted from gold ore using a combination of chemical processes. The most common method involves cyanidation, where cyanide solution is used to dissolve the gold from the ore. The dissolved gold is then extracted from the solution through adsorption onto activated carbon, followed by refining to obtain pure gold.
Gold is typically extracted from gold ore through a process called cyanidation, which involves leaching the gold out of the ore using cyanide solution. The gold then forms a soluble cyanide-gold complex that is extracted from the solution through various methods, such as carbon adsorption or precipitation. Finally, the gold is further purified and refined to remove impurities and obtain pure gold.
Gold that is extracted from the earth is in its ore form, meaning that the gold is mixed with other minerals in the rock. The gold ore is processed by breaking it up into small pieces and heating it to remove the gold, which is extremely soft and melts at a very low temperature, leaving the rock behind.

The purity of gold ore is typically measured in karats, with 24 karats being pure gold. Assuming the gold ore is 24 karats, you will obtain approximately 0.9999 grams of pure gold from 1 gram of gold ore.
In the old days it was extracted from mines with pick axes. Gold nuggets were dug from veins of crystal quartz that often included silver, mercury, and lead. Today most of that ore has been tapped, and new methods are employed. The gold is no longer even visible to the naked eye--it is dust, scattered throughout an ore body in a zone. Strip mined ore is piled on slanted V shaped sheets of plastic where it is sprayed with a solution of cyanide. The cyanide bonds with the gold which settles into a pond. The pond is drained, the rich ore scooped up and further processed to recover the gold. A profitable ore body may contain as little as 0.02 oz of gold per ton of ore. I have toured several gold mining operations in northern Nevada, and have staked claims for other mines there.
