Review of barriers to reduce mercury use in artisanal gold mining

Most gravity concentration methods used in artisanal mining are not continuous (i.e., they must be stopped to discharge the concentrate). Miners working with alluvial ores control their activities based on how "yellow is the concentrate". This is a very common mistake. High gold grade in concentrates do not reflect high gold recoveries.
