Ghana's small-scale mining has evolved beyond the reach of current small-scale mining legislation. The formalization process enacted in the small-scale mining laws is ineffective because it is unable to capture the magnitude and complexity of what now encompasses Ghana's small-scale gold industry.

Basic Gold Prospecting Exploration Methods

Prospecting and exploration that is a search for precious metals deposits is not a simple process because big deposits were discovered a long time ago. There are several places with important content of precious metals waiting for skill prospectors. The large mining companies of the world are focused in big deposits and the small deposits are attractive for small miners and perhaps their

Understanding Gold Mining

Jul 05, 2013In the small-scale mining process, excess mercury runs off into the river basin and contaminates the surrounding ecosystem. Some techniques are so crude that, for every 1 gram of gold produced, more than 3 grams of mercury run off into the water. The gold nuggets extracted by small-scale miners contain high levels of mercury.

Gold mining

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.
