Mine tailings: How to effectively manage the risk
The tailings dam seems sound for the moment but may become an issue in the years to come. Communities live downstream from both the pit and tailings dam and allegations of pollution are routine. The risk register process raises the requirement for information about water and associated geology from various sources.
Karara Mining to stack tailings high to keep costs water use
With environmental and cost factors in mind Karara wanted to look at ways to have greater control over water assets on site. The ability to reuse and recycle water in the mining process would lead to substantial cost efficiencies by minimising the amount of makeup water needed for the mining operation FLSmidth said.

Big River Mine Tailings National Priorities List NPL
It has been estimated that some 250 million tons of hazardous mining waste such as lead mill waste tailings and chat were produced in the Old Lead Belt from processing lead ore. Mining activities in St. Francois County have contaminated soil sediment surface water and groundwater with elevated levels of heavy metals primarily lead.
The Mining Process - Newmont Corporation - About Us
The tailings are stored in tailings dams which are lined with impermeable layers. While the cyanide levels in the dam are safe steps are taken to keep wildlife away from the dams. Over time the chemicals break down and the solids settle to the bottom so that the water can be returned to the plant to be used in processing.We then smelt the

Tailings dam failures linked to hefty bonuses for mine
Tailings dam failures increasing. The number of tailings dam failures worldwide has doubled in the past 20 years from eight between 1999 and 2003 to 16 between 2014 and 2018. In addition to the push to reduce costs and increase production increased amounts of waste from mines is also factoring into the increase in accidents the study says.
