ARTISANAL GOLD MINING CHALLENGES WITH SPECIAL

2019-6-25  Artisanal Gold Mining (AGM) operations in the global level are unregulated, informal and transient. Rudimentary mining and processing techniques used in AGM often result in degraded environmental, safety, health and social conditions. The main objective of the study is to assess challenges in AGM with special reference to gold mining and processing methods in Asgede Tsimbila and Lailay-Adiabo Woredas, Ethiopia. Qualitative and quantitative research methodology was used of this study. The views, opinions and attitudes of 64 miners and 20 local chiefs were gathered concerning about AGM methods and techniques. AAS instrument is used for the geochemical analysis of the soild waste materials from the artisanal gold mining and processing techniques. The miners are searching gold from the primary gold by digging more than 35meters into hard rocks, from shallow subsurface and surface soil using the most traditional tools to get gold. About 85.94% of the miners agreed that artisanal gold mining methods and processing
