Strain and sluice (IMAGE)
Caption
Miners pose for a photo while one pours an earth-toned liquid through a strainer and down a sluice to separate out the fine-scale gold-laden sediment from larger soil particles.
By collaborating with mining communities in Senegal, Michigan State University researchers were part of a team that found practical solutions to reduce mercury emissions from artisanal and small-scale gold mining.
