What are tailings dams IndustriALL

What are tailings dams Tailings dams are used to store water and waste that come as by products from the mining process It is estimated there are at least 3 500 tailings dams around the world But as there are around 30 000 industrial mines the number of tailings dams is likely to be much higher

Tailings Earthworks

Tailings most often in the form of a wet slurry are conventionally stored above ground behind earthen dams There is no comprehensive global registry of tailings dams It is estimated there are around 18 000 dams 3 500 of which are active However that number may be much higher For example China alone has more than 12 000 tailings dams

PDF Filtered Dry Stacked Tailings The Fundamentals

Filtered tailings are becoming an increasingly common consideration for tailings management at many mines There are more filtered dry stack tailings storage facilities than there are surface paste facilities yet the amount of guidance documentation on filtered tailings is virtually non existent in compare to those same paste tailings facilities

Tailings Dam Failures Factors Causes and Examples

There are many examples where tailings dams have failed and caused catastrophic disasters such as environmental pollution ecosystem damage and loss of life The causes of mine tailings dam failure are different as each failure is always site specific although common themes always emerge around In higher rainfall climates tailings dams may

Risk and the mining industry after the Brumadinho tailings dam failure

Tailing dams like the one that failed at Brumadinho are common in the mining industry They are constructed to form tailings ponds huge basins sometimes spanning square kilometres used to store by products from mining operations such as ground up rock and sand as well as often toxic chemical reagents used to extract commodities

About Tailings Global Tailings Review

Tailings is a common by product of the process of extracting valuable minerals and metals from mined ore They usually take the form of a liquid slurry made of fine mineral particles created as mined ore is crushed ground and processed Effective tailings management is integral to the safe and sustainable production of metals and minerals

Tailings Dam Failures Factors Causes and Examples

Typically mine tailings are pumped as a slurry to a storage dam known as a mine tailings dam This dam follows similar engineering principles to water storage and hydroelectric dams Characteristics that can be reasonably investigated at the design stage and may contribute to foundation failure are Geological structures Landslip surfaces
