I may stand to be corrected but my understanding, the most simply process would be to heat the entire mixture of metals to melting point then slowly cool the mixture. The different metals will have different melting point and the various different metals will solidify on the surface of the solution. You could remove the metals until you have relatively pure gold left.
I am unsure of the industrial process but i belive it would be similar.
Mercury can form an amalgam with gold, which is a mixture of the two metals. This can make it easier to extract gold from ore, but it can also lead to environmental pollution if not properly managed.
It is a homogeneous mixture.. NOT a pure element because of the carat gold
Gold itself is an element. All of the gold you are likely to see (rings, watches, plating, etc.) is an alloy (mixture) of gold and other metals. Even "pure gold" jewellery (24 k) is only +99.9% pure
You can separate gold from a mixture of gold and zinc using a process called selective precipitation. By adding a chemical reagent that reacts with zinc but not with gold, the zinc can be precipitated out of the solution, leaving the gold behind. This process allows for the physical separation of the two metals.
Fourteen carat gold is a mixture of 58.5% pure gold and 41.5% other metals such as copper, silver, or zinc. This combination of metals makes the gold alloy stronger and more durable than pure gold.

gold, silver and bronze
Fourteen carat gold is a mixture of 58.5% pure gold and 41.5% other metals such as copper, silver, or zinc. This combination of metals makes the gold alloy stronger and more durable than pure gold.
22 carat gold is not an element on its own but a mixture of gold and other metals such as copper and silver. The purity of 22 carat gold is 91.7%, with the remaining 8.3% made up of the other metals for added durability and strength.
Yes it's an alloy of many different metals therefore it is a mixture
18 carat gold is a mixture because it is composed of 75% gold and 25% other metals such as copper or silver.
Depending on the piece, gold jewelry can be a mixture. If it is solid gold, then no. The highest concentration of pure gold is 24kt but it is very malleable or easy to distort. Anything less is most likely a mixture. All 22kt, 18kt, 14kt gold etc. is alloyed with other metals such as silver, copper etc.
18 karat gold is a mixture because it is composed of gold as the main element along with other metals such as copper, silver, or zinc. The karat measurement indicates the purity of gold in the mixture, with 18 karat gold containing 75% gold and 25% other metals.
14 karat gold is a solution because it is a homogeneous mixture of gold and other metals like copper, silver, or zinc. The gold is the solvent, while the other metals are the solutes that are dissolved in the gold.
