Placer Gold Mineral Processing
About Placer Gold. Placer gold refers to the gold formed by the rock gold in the mountain washed by the river and separated from the quartz vein. Because this kind of gold is as fine as sand, it is called placer gold. Gold mining is divided into rock cave digging and panning in rivers and streams containing gold. For example, gold taken from mines is called …
