Prospecting Placer Gold Deposits

The most important type of placer deposit results from the weathering and disintegration of lodes and of rock formations containing gold disseminated through them, the erosion and transportation of these rocks by running water accompanied by further disintegration and liberation of the gold from the enclosing rock minerals, and the concentration of the gold in places where the velocity of the transporting medium (flowing water) is such that the gold

Placer mining

Overview

A number of methods are used to mine placer gold and gems, both in terms of extracting the minerals from the ground, and separating it from the nongold or nongems.
The simplest technique to extract gold from placer ore is panning. This technique has been dated back to at least the Roman Empire. In panning, some mined ore is placed in a large metal or plastic pan, combined with a generous amount of water, and agitated so that the gold particles, being of higher density
