The gold buyers sometimes put the specks of gold on a spoon or even a ladle-like apparatus and burn it under a sizzling fire, which is usually a Bunsen burner. At this stage, it is the mercury which is unwanted and it will be subjected to heat.
In just a few seconds, it evaporates leaving behind an even smaller speck of gold. The gold buyer once satisfied with the quality, pays up, stores his treasure while the miner goes back to the mine happy.
