Extraction of Gold by the Amalgam Process. The amalgam process is the oldest technical method of extracting gold and was used in antiquity. With the amalgam process the gold bearing rock is likewise crushed to fine sand. Afterwards mercury is added to the rock dust. Gold has the property that enables it to join to the surface of the mercury.
Yet mining the ore is just one stage in a long and complex gold mining process. Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well as how to extract and process the ore efficiently, safely and responsibly.
The Gold Mining Process In addition to cyanide processing, gold ore is also processed with gravity separation. Advanced technology has enabled the amount of gold mined and processed to steadily increase over the years.

Processes based on direct chemical purification and recovery from solution as elemental gold can greatly speed gold processing and virtually eliminate expensive in-process inventories. Refining from scrap. The processing of gold scrap varies not only with the gold content but also with the amenability of the gold in the scrap to extraction.
Gold miners too take special care to make the impact of mining for gold as light as possible. Reclaiming land to its previous natural state is the final and perhaps most important step to ensuring the process of obtaining gold doesn't result in permanent damage to the landscape.
