Valorization of Gold ores by the sustainable management of gold panning activities in Madagascar

Sciences de la Terre

Artisanal mining takes an important place in the Malagasy mining sector because it is one of the engines of local economic development. Indeed, such a study makes it possible to serve as a reference for the understanding of the importance of gold panning, the impacts of exploitation on the environment, on local economies as well as the social development of populations. The highlights of the study highlight a much higher gold production in Madagascar, than that officially declared, despite its current state of exploitation: Based on official exports of about 11 tons in 2017 and about 3 tons in 2018 and 8 tons in 2019 on the largest gold sites of Madagascar, and this despite the under-equipment and the under-technicality displayed by gold miners. This study aims to acquire new techniques for processing gold ore and manage environmental impacts. For the realization of the study, we valorized the following specific steps namely the typologies, the different modes of gold mining, the environmental stakes of artisanal mining, the impacts of gold mining in natural environments, and the valorization of gold ores by advanced processing techniques. The results expected by this study concern the increase of gold production by the appropriate processes, the measures of mitigation of environmental impacts in order to draw the recommendations for a sustainable management of the gold panning activity in Madagascar from the social, economic and environmental point of view.
