How gold is extracted? Answers
They first mine it. There are several ways. A lot of gold is in ore deep underground; they dig down to it, break it up and haul it out. Other gold is in stream beds, and machines called sluices

With gold having been in use since the dawn of history and new mining still occurring, it may seem strange to think of a day when there is no more gold to be extracted from the ground. nevertheless, like any other limited natural resource, there is a finite supply of gold in the world. at some point, the worlds supply of new gold will run out.
#173;Smelting, which results in nearly pure gold, involves melting the negative terminals in a furnace at about 2,100 degrees F (1,149 degrees C). When workers add a chemical mixture known as flux to the molten material, the gold separates from the metal used to make
#0183;#32;When gold is mined, it must be extracted from its surrounding materials. One of a number of precious metals, gold is found in the ground, either in alluvial deposits, noncohesive sediment, or other rocks. It is found in formations of
#0183;#32;Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.
#0183;#32;Unreactive metals such as gold are found in the Earth''s crust as uncombined elements. However, most metals are found combined with other elements
Gold ore is not pure, but instead intertwined with other metals like silver. In the mill, the large chunks of ore are crushed and broken down until it is a powdery sandlike mixture of gold, silver, and rock. It is then mixed and ground with generous amounts of water and cyanide until it becomes a pulp, which flows into large settling tanks.
Using a chemical solvent, usually cyanide combined with oxygen, the gold is extracted from the pulp inside these tanks; but it is still not pure gold. This process is known as carboninpulp. The result is gold that is attached to carbon. The next step is to remove the gold from the carbon bonds.
#0183;#32;How to Extract Gold from a Rock. Prospecting for gold can be a fun hobby, though it''s a lot of work! You may be able to harvest gold flakes from rock if it contains gold among its minerals. The safest way to extract gold from rocks at home...
Another process involves ground ore being passed over plates which are coated with mercury. The gold and the mercury form an amalgam, leading to the name of the process, amalgamation. Once the amalgam has formed, it is heated until the mercury gas is boiled off, leaving the gold. The mercury gas is highly toxic and must be handled carefully.
The Silver Extraction Process. The Silver Extraction Process. The ore used to extract silver was not a silver ore but Lead Sulphide (formula PbS), known as Galena or Galenite (named by the Roman Pliny) which contains 87% lead.
Silver is mined through a series of mines known as an open cut mine, a shaft mine, and a panning. Silver (Ag) is a precious metal used in jewelry and cutlery. It is extracted from copper amp; lead ores.

While many technologies exist, Silver is typically mined through a process that uses gravity to break and extract ore from large deposits. The exact method of ore removal used varies by the physical characteristics of the rock surrounding the metal, as well as the unique shape of the deposit.
Silver is predominantly found in ores that also contain copper, lead, zinc, and other metals. These ores are drilled out of the ground and loaded onto trucks for transfer to refining facilities. The method used to extract silver is dependent upon which other types of metals are found within the same ore.
