Description

ABSTRACT

In Burkina Faso, artisanal mining is practiced in all thirteen (13) regions. The country made 2,262 million USD gold exportation in 2019 against 3,568 million USD in 2020. Today, with more than 500 active sites, artisanal gold mining employs over a million people. The studied site is located in the rural commune of Silmiougou in the department of Boussé (Burkina Faso). The artisanal mining site of Silmiougou open in 2014. The waste produced on the site is generally not managed with crushing and grinding phase employing more children. The latter are exposed to injuries from flying stones, respiratory illnesses from dust and deafness from noise. Skin infections can also occur from repetitive contact with ore flour, waste oils and other hydrocarbons. During the ore washing and refining phases (amalgamation, burning and cyanidation), unprotected handling and continuous exposure to chemicals can be sources of mercury and cyanide poisoning. Measures must be taken to support or compel the artisanal gold miners for the proper management of the Silmiougou site. These measures include the enforcement of regulations on gold panning by emphasizing the environmental aspect and ensuring compliance with existing laws along with the technical supervision of artisanal gold miners.
