May 11, 2018 The Mercury Problem in Artisanal Gold Mining. Mercury‐based artisanal and small‐scale gold mining (ASGM) causes more mercury pollution than any other human activity.1 In this practice, mercury metal is used to extract gold from ore as a stable amalgam. The amalgam is then heated to evaporate the mercury and isolate the gold

Sep 01, 2020 Occupational injuries, though preventable, have been described as a major public health problem. In artisanal and small-scale gold mining (ASGM), little is known about the risk factors to injuries. In 2018, we examined injuries and the potential risk factors among ASGM workers in Rosterman, Kakamega County, Kenya. A descriptive cross-sectional survey was

In addition to just examining gold price charts, you can also use the gold/silver ratio price chart. The gold/silver ratio is simply the amount of silver required to buy a single ounce of gold. For example, if gold is at $1200 per ounce and silver is at $15 per ounce, the ratio would be calculated as $1200/$15 = 80
