Placer mining Placer mining is the technique by which gold that has accumulated in a placer deposit is extracted.Gold Mining and Processing: Everything you Need to Know,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. For example, the worldwide production of gold in 2006 was 2360 metric tons.9 Step Process for Discovering, Mining & Refining Gold,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.
