Something else.
Gold is native in the reactivity series, meaning it is found in its elemental form in nature without needing to be extracted from a compound.
Metal cannot be extracted from Gold, as Gold itself is a metal.
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 can take millions of years to form in nature through geological processes involving heat and pressure.
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.
Einsteinium is an artificial element, not extracted from natural materials.
Gold is extracted from the earth itself, near the place underground where coal miners work.
Gold is typically mined as ore containing gold particles, which are then extracted through various methods such as cyanidation or smelting. Once extracted, gold can be refined through processes like cupellation, where impurities are removed through oxidation. In terms of purity, gold is often measured in karats, with 24 karat gold being the purest form.
No. it changes its form in some temperature.
Gold has been extracted from seawater, but the cost is not worth the effort for the very small amount that can be obtained.
No. Diamond is a pure form of carbon, and this is not soluble in mercury. Gold and silver may be amalgamated with mercury.
Gold can exist as native gold in nature because it is relatively unreactive and stable. This means that it does not readily combine with other elements to form compounds, allowing it to exist in its pure metallic form. Additionally, gold is often found in quartz veins, where it can crystallize and form nuggets or grains.
