Gold parting is the separating of gold from silver.Gold and silver are often extracted from the same ores and are chemically similar and therefore hard to separate. Over the centuries special means of separation have been invented. The very earliest precious metals had mixes of gold and silver; gold and silver alloy is called electrum.With the advent of coinage, methods had to be invented to ...
Black sand deposits, which are composed of heavy metal materials such as iron and hematite, are common in areas where gold is found.

Because platinum is so rare, it must be extracted after being mined through a process that involves crushing it into incredibly small particles and separating these particles from one another. This is known as the flotation separation method, and produces a frothy layer of particles that can be skimmed to provide the extracted platinum.
one way is to increase heat and pressure to turn one into a liquid then disperse it. Gold has a lower melting point so it would turn into a liquid at a cooler temperature than platinum, then you ...
