Gold mining activity is a source of supply in many areas of the world, and especially in developing countries, it is practiced illegally and by applying unsafe techniques. Particularly in Ecuador, artisanal and small-scale gold mining (ASGM) is widespread, and it is based on the use of toxic substances, such as mercury (Hg), in …

Traditional gold mining (TGM) is among the off-farm income sources of smallholder communities in the highlands of Ethiopia. However, information on their impact on land degradation, taking soil ...

Challenges and ways for an integrated management of water resources in this highly complex area are outlined, including possible consequences of the future cessation of mining and the resulting ...

As findings indicate in (Table 3) that overall impacts of the mining operations the dehydration of the brook (10.6%), soil erosion (20.8%), and damage of the street (17.6%) are major consequences of the mining operations in study area. Extracting gemstones and gold mining negatively affects the environment through destruction of …

Abstract. In many areas of China, agricultural land is subject to heavy metal contamination from mining activity. This study investigates an in situ remediation program suitable for the recovery of heavy metal-contaminated agricultural soil around mining areas. A 1-year field experiment was conducted in a gold mining area of Tongguan, …

Indonesia is included in the top ten gold producers worldwide (with production in December 2020 alone reaching 130 tons) [ 1, 2] and is host to large number of artisanal and small-scale gold mining (ASGMs) businesses and operational facilities. The definition offered by Wiriosudarmo (1999) in Prabawa (2020) [ 3] states that ASGM can …

Indeed, Commercial Scale Gold Mining is believed to have commenced in Ghana in. the early 19th century by the British. After the ban in Gold mining was lifted in December 2018, there has been a ...

Due to the depletion of placer gold reserves in old mining areas, existing gale-lixiviation dumps are processed to extend the life of mines and maintain the level of gold production. Dump washing results of past years (25–30 years ago) indicate that the gold content in these dumps is approaching present-day conditions for open-pit mining …
