The gold that is used to make jewelry is actually a gold alloy a mixture of pure gold and other metals, which are added in to make the alloy harder. So, However, there are many other metals that are non magnetic, which can also be plated with gold and will not react to a magnet.
Cyanide. Cyanide solution extracts gold from the devices, and it is a general process. The cyanide clubs with gold and forms gold ions. The ions later can be distilled, and the gold can be obtained. This is a solution to extract gold that cannot be done easily; however, there
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 the terminals. Workers pour off the flux and then the gold.
This Guide is best suited for gold plated or pure gold object. THIS SHOULD ALSO NEVER BE ATTEMPTED INDOORS. *Cupellation is a refining process in metallurgy, where ores or alloyed metals are treated under high temperatures and controlled operations to separate noble metals, like gold and silver, from base metals like lead, copper, zinc, arsenic
