Introduction. Smallscale gold mining around the world is usually thought of as an informal activity (Hentschel et al., 2002).In many states, smallscale mining is illegal and dealing or exporting smallscale mined gold amounts to smuggling.
Historically, mercury was used extensively in placer gold mining in order to form mercurygold amalgam with smaller gold particles, and thereby increase the gold recovery rates. Largescale use of mercury stopped in the 1960s. However, mercury is still used in artisanal and smallscale gold mining (ASGM), often clandestine, gold prospecting.
By much smallscale mining equipment and processing beneficiation practice, people discovered that gravity is the most efficient and the most stable method to grade smallscale gold mine. The smallscale gold mine in different regions by the above processes can .

Gold deposits along the general gold path can be small or large, depending upon the size of the gold trap. The most important type of gold trap in river mining is called the "paystreak". Paystreaks always form along the gold path where the river''s flow slows down on a large scale during a major flood storm.

ceased. This form of mining usually involves the extraction of secondary gold from placer deposits (alluvial, colluvial or elluvial), which can be liberated and treated using gravity methods. In the Guianas, the most popular form of smallscale gold mining is referred to as "land dredging", a combination of hydraulicking and suction dredging.

One of the most widespread gold extraction methods used by smallscale gold miners is whole ore amalgamation. In brief the method is as follows. After gold ore is mined, it is crushed to about walnut size mostly by hand. The crushed material is transferred to a metal drum and milled with hard metal rods or balls together with water and mercury.
