Tailing Disposal Methods and Tailings Dam

For a large dam a mechanical excavator is employed instead of hand labour Fig 70 shows the method of construction If a large proportion of the tailing is coarse and granular, the wall can sometimes be built by direct deposition from the pulp as it enters the dam The use of mercury in gold mining is causing a global health and environmental crisis Mercury, a liquid metal, is used in artisanal and smallscale gold mining to extract gold from rock and sediment Unfortunately, mercury is a toxic substance that wreaks havoc on miners’ health, not to mention the health of the planetEnvironmental Impacts of Gold Mining Brilliant Earth
