This paper, the second of our series on alluvial gold exploration in Ghana, discusses some of the causes of the failures of placer gold exploration programmes in the country that were identified in the first article. The need to recognize and rectify the common lapses and peccadilloes displayed by Ghanaian exploration personnel is important …
Ghana's gold deposits can be classified as primary along shear zones in the Birimian gold belts (mesothermal quartz-vein gold deposits) or secondary free gold in conglomerates of the Tarkwaian Banket Formation (paleoplacer deposits) (Milési et al., 1991; Sunkari, 2018).A common method involving an amalgamation stage uses mercury …
1. Introduction. Mantey et al., defines "galamsey" as the practice of illicitly mining and/or extracting gold found either at or below soil and water surface in Ghana. It is an illegal or unregulated form of artisanal small scale gold mining (ASM) and could either be in a stand-alone mining mode, a stand-alone processing or gold extraction …
Alluvial gold is found beneath the surface at the bottom of a creak or stream. Alluvial gold mining is the process of extracting gold from these creaks, rivers and streams and is generally considered to be the most environmentally friendly method of gold mining as a result of the reduced environmental impact when compared to underground mining. ...

The extraction methods in Ghana can be categorized into the following three groups: shallow alluvial mining; deep alluvial mining; and hard rock (lode) mining. Shallow …
The alluvial mining method is done in placer deposits or waterlogged areas where there are alluvial gold deposits, usually in a low-lying area or at the riverbeds. For the initial phase of extraction of alluvial gold deposits in low-lying areas, miners clear the vegetation and then excavate the soil to reach the gold-rich layer (Aryee et al ...
Ghana is known globally for gold (and diamond) mining, and this activity contributes more than one-third of Ghana's export revenues. During the global COVID-19 pandemic, the mining sector was one major area that was largely considered as an essential sector, especially in Ghana ( GCM, 2020 ), possibly due to its impact on the economy.
