Mining and Environmental Degradation: a Gift Brings Grief Scenario for Mining Communities in Sierra Leone
Sierra Leone is blessed with abundant natural resources but yet prone to environmental degradation due to the mining operations. Most often, the mining communities are faced with social tensions, as a result of the possible trade-off between the expected employment impact and the cost of mining operations to the environment. Over the past decades, the contribution of the mining sector to the de...
متن کاملTreatment of small scale gold mining wastewater using pilot-scale sedimentation and Cocopeat filter bed system
The use of amalgamation process to recover gold from mined ores by the small-scale gold miners in the Philippines and other developing countries produces and dispose of untreated wastewater to the receiving water bodies. In this study, a field-scale filter bed system was constructed to treat heavy metal metal-laden wastewater collected from small-scale gold mining site in Paracale, Camarines No...
متن کاملTackling Youth Unemployment in Sub-Saharan Africa: Is there a role for Artisanal and Small-Scale Mining?

Over the past decade, hundreds of thousands of the region's youth have pursued work in the ASM economy in various capacities, decisions which have brought much-needed stability...
متن کاملSilica Exposures in Artisanal Small-Scale Gold Mining in Tanzania and Implications for Tuberculosis Prevention.
Gold miners exposed to crystalline silica are at risk of silicosis, lung cancer, and experience higher incidence rates of pulmonary tuberculosis (TB). Although the hazards associated with mercury exposure in artisanal small-scale gold mining (ASGM) have been well documented, no published data was available on crystalline silica exposures in this population. Air sampling was conducted in the bre...
متن کاملErgonomic Hazards Associated with Small Scale Mining in Southern Africa
The aim of this paper is to examine the ergonomic hazards associated with small scale mining in Southern Africa. A number of ergonomic health hazards affect the workers involved in the small scale mining. Many people in Southern Africa are working in the informal mining sector without any guarantee of occupational health and safety. Actual work places in deep level mines present unique challeng...
