Artisanal and small-scale gold mines (ASGMs) have been accompanied by widespread usage of mercury amalgamation to extract from ores, putting Indonesia among the top three global emitters this pollutant posing potential risks marine ecosystem human health. Although use has largely eliminated following signature Minamata Convention on Mercury, practice in ASGM persisted several regions, including...

French Guiana is well endowed with gold like its neighbours in the Proterozoic Shield, yet it has no industrial mines, and most of current production comes from illegal Brazilian miners. This situation rooted history extractive frontiers, which began discovery 1855. experienced two rushes influenced by price gold, first during standard period, he second Chinese supercycle. The wave diverse ethn...

Few investigations have focused on the potential uses of artisanal gold (Au) mine tailings, despite fact that mining activity contributes to environmental issues such as greenhouse gas. Mineralogical characterizations tailings in Miyove (Baradega and Masogwe) Rwanda were investigated for utilization a source valuable gold, using centrifugal separation technique. Results X-ray diffraction analys...

OBJECTIVE While artisanal mining takes place in casual framework and with total ignorance of good practices, few studies have focused on the origin of hazards specific to each workplace constitutive of this exploitation facility. Nevertheless, this study is a condition of an efficient occupational health and safety control in this sector. MATERIALS AND METHOD We took the effort to identify di...

Oxidation of sulfide-containing ores is the main cause of Acid Mine Drainage (AMD), which is an environmental problem associated with both the abandoned and active mines. Iron-bearing sulfide minerals can be oxidized and form mine waters with high sulfate content, low pH, high electrical conductivity, high redox potential, and high concentrations of iron, aluminum, and other heavy metals. In th...

The usage of inefficient techniques in artisanal gold mining is quite common, either to extract the ore or processing it, and related to environmental contamination. This paper analyse the mineral processing of a case study in Peru (San Cristobal) with the aim to improve the gold recovery process and the environmental impact. The process of amalgamation (gold-mercury) has been found as ineffect...
