2022年1月31日 Introduction. Small-scale mining (SSM) is mining by individuals, groups, families, or cooperatives with minimal or no mechanization, often in the market's informal
Artisanal and small-scale gold miners pour mercury into ground ore where it merges with gold flecks to form an amalgam— essentially a ball— of mercury and gold. They then burn this ball to evaporate the mercury so
Health problems of gold miners who worked underground include decreased life expectancy; increased frequency of cancer of the trachea, bronchus, lung, stomach, and liver;

2022年1月1日 1. Introduction. Globally, it is acknowledged that artisanal and small-scale gold mining (ASGM) has expanded dramatically in most low- and middle-income countries during the last decade due to increasing demand for valuable metals and the lucrative potential of gold coupled with the prevalence of poverty (Basu et al., 2015, Cossa et al.,
2021年11月24日 Exposure to heavy metals in mining activities is a health issue among miners. This study was carried out at three small-scale gold mining sites situated in Banmauk Township, Myanmar and aims to
The present review discusses the hazards faced in personal and domestic use of gold and the far greater risks presented through occupational exposure to the metal in mining and processing gold ores. In the last situation, regular manual contact or inhalation of toxic or carcinogenic materials like mercury or arsenic, respectively, presents far
2018年10月1日 Gold mine tailings are reported to have low reactivity and need the addition of co-binder to achieve a strong matrix [17]. Large amount of different cationic elements from gold mine tailings can be immobilized by alkali activation of optimized system [11, 18]. High levels of As and V were leached out from the alkali-activated mine tailing
2022年2月9日 The global mining of gold among artisanal and small-scale mines is associated with numerous hazards. Traumatic and occupational hazards include mine collapse and cave-ins, crush injuries, burns, falls, barotrauma, drowning, asphyxiation, lacerations injuries from mining equipment, temperature-related maladies, and noise

2022年3月15日 Background: In 2017 around 14-19 million miners were exposed to multiple hazards in artisanal and small-scale gold mining (ASGM). ASGM is characterized by basic and compromised mining methods with either very limited control of hazards or none at all. There is little knowledge about health and safety among artisanal and small-scale gold
Health problems of gold miners who worked underground include decreased life expectancy; increased frequency of cancer of the trachea, bronchus, lung, stomach, and liver; increased frequency of pulmonary tuberculosis (PTB), silicosis, and pleural diseases; increased frequency of insect-borne diseases, such as malaria and dengue fever; noise-induced
