Ancient Gold Mining Activities in India - An Overview
Gold was obtained through washing or panning of the river sands during initial periods of civilisation. With the advent of knowledge of metallurgical processing of ores it was recovered through mining of in-situ quartz reefs, and then from auriferous sulphide ores. The metal mining activities are evidenced in the form of large number of ‘ancient metal mines’ or ‘old workings’ and ‘placer mining...
متن کاملMalaria in gold-mining areas in Colombia
Gold-mining may play an important role in the maintenance of malaria worldwide. Gold-mining, mostly illegal, has significantly expanded in Colombia during the last decade in areas with limited health care and disease prevention. We report a descriptive study that was carried out to determine the malaria prevalence in gold-mining areas of Colombia, using data from the public health surveillance ...
متن کاملKronenberg, J. Global warming, glaciers and gold mining. GLOBAL WARMING, GLACIERS AND GOLD MINING
Two case studies (Kumtor in the Kyrgyz Republic and Pascua-Lama in Chile–Argentina) are analysed, illustrating how gold mining interferes with glaciers and how this may be affected by changing perceptions on global warming. Although global warming presents new opportunities for the mining industry, increasing the physical accessibility of resources previously covered with glaciers, it may also ...
متن کاملEvaluation of Occupational Therapy Practices for Artisanal Gold Mining in Bagega Community, Zamfara State, Nigeria
Background: The enormous numbers of people involved in artisanal gold mining (AGM) together with primitive methods being used in processing gold have resulted in health and environmental challenges. Based on this, both the local and international stakeholders in mining and health sectors engaged in therapeutic practice to mitigate the challenges. Methods: Physical observation and soil samples ...
متن کاملElectricity generation by Geobacter sulfurreducens attached to gold electrodes.
The versatility of gold for electrode manufacture suggests that it could be an ideal material for some microbial fuel cell applications. However, previous studies have suggested that microorganisms that readily transfer electrons to graphite do not transfer electrons to gold. Investigations with Geobacter sulfurreducens demonstrated that it could grow on gold anodes producing current nearly as ...
