چکیده
Gold mining is a significant strategic sector for local, regional, and national economies. The rapid development of coexisting camp-type artisanal small-scale gold (C-ASGM) large-scale (LSM) accelerates the environmental health risks associated with mercury pollution; however, transformations sites have not been well quantified. This study used remote sensing (the PlanetScope smallsat constellations systems) to investigate C-ASGM LSM in Gorontalo, Indonesia, from 2019 2022. results show positive increase extent barren land across all zones, resulting road network construction connecting southern port major sites. Notably, greater landcover after 2020 were attributed dumping underground soils excavated using shaft-mining method. findings this expand our understanding operations quantify mining-induced changes. These are anticipated assist timely monitoring identification areas, rates, volumes, together existing C-AGSM’s reactions LSM’s massive developments. also helps detect possible local-level socioenvironmental impacts shape changes, leading human disasters, including landslides floods.

Treatment 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 کاملManagement challenges on small-scale gold mining activities in Brazil.
This article presents a focused study of environmental management in small-scale gold mining, called garimpo, at the Tapajós River in the Amazon basin (Brazil). Environmental management is necessary in this very important area not only for Brazil but for the general world welfare. The fact that this is a very dispersed area, with a very low economic and education level, complicates the issues. ...

متن کاملFrom large-scale to small-scale dynamos
Several recent advances in turbulent dynamo theory are reviewed. High resolution simulations of small-scale and large-scale dynamo action in periodic domains are compared with each other and contrasted with similar results at low magnetic Prandtl numbers. It is argued that all the different cases show similarities at intermediate length scales. On the other hand, in the presence of helicity of ...
