The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold.

placer gold deposits in the country and are quintessentially the main locations of small-scale gold-mining activities. Small-scale diamond mining is more localized, with 60 per cent of licensed operations occurring at the Ghana Consolidated Diamonds (GCD) site at Akwatia, and the balance within surrounding areas [4].

The use of the "all-in sustaining costs" and "all-in costs" metrics has been widely adopted by gold mining companies as part of their overall reporting disclosure. These non-GAAP metrics have helped provide greater clarity and improve investor understanding. All companies involved in gold-mining are encouraged to use these metrics.

Historically, mercury was used extensively in placer gold mining in order to form mercury-gold amalgam with smaller gold particles, and thereby increase the gold recovery rates. Large-scale use of mercury stopped in the 1960s. However, mercury is still used in artisanal and small-scale gold mining (ASGM), often clandestine, gold prospecting.

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 "pay-streak". Pay-streaks always form along the gold path where the river's flow slows down on a large scale during a major flood storm.

The use of mercury in gold mining is causing a global health and environmental crisis. Mercury, a liquid metal, is used in artisanal and small-scale gold mining to extract gold from rock and sediment. Unfortunately, mercury is a toxic substance that wreaks havoc on miners' health, not to mention the health of the planet.

Gold panning is the most common method used by small scale prospectors, but larger mining equipment like gold dredges, sluice boxes, drywashers, and many other types of equipment uses gravity separation to discharge lighter material while retaining gold.

Some gold can be found by panning in rivers; heavy gold will remain in the pan, whereas lighter rocks and minerals float out. This small-scale form of gold mining has little effect on the body of water, but the large-scale practice of mining gold from ore can have tremendous negative effects on water quality.

This sector is also responsible for the largest releases of mercury to the environment of any sector globally. A major source of air pollution from mercury, artisanal and small-scale gold mining releases approximately 400 metric tons of airborne elemental mercury each year.
