What are Taillings?

In the mining industry, the term tail or tail concerns the waste material that remains extracted from mined ore in the mine processing plant after most of the required minerals. Tails, sometimes also called Slickens, Slickens or Leach Resium, usually consist of very fine particles of the Earth or crushed rocks and minerals mixed with water and other chemicals added in metallurgical processes of mineral extraction. This waste material can be processed in different ways, depending on its composition, water content and regulations for mining in specific jurisdiction. For example, the material can be mixed with water and pumped into the ocean or waterways, stored in specially built surface ponds or underground devices, dried and supplied, or treated in different ways to be safer to use and process. The disposal of the tail is the main part of any mining operation and this material can cause health and environmental problems if it is not solved correctly.

taillingS often contain some of the same minerals to which the ore has been mined, and sometimes redesigned to extract this material. Mining waste also usually contains arsenic, sulfur, various naturally radioactive materials and heavy metals such as mercury and cadmium. The additives used in the chemical processing of ore are also often part of the scarves. This may include oil, fat, cyanide, sulfuric acid and calcium in the form of lime.

is a common way to store tails in ponds and dams. For example, coal mining produces waste material called coal porridge, consisting of very fine particles of coal mixed with water, which is often stored in the type of dam called coal porridge. Tails can also be stored underground or drained and stored in storage devices. Often toxic waste content makes it difficult to maintain any storage and any leakage of overs passing can cause environmental damage and affect health BLicky inhabitants.

worldwide, the mining industry produces hundreds of thousands of tons of scarf every day. Many mining companies seek to find methods of treating their waste material, so it does not require expensive long -term storage. The aim is often to turn waste into attic material that can be used for projects of mine reclamation and planting vegetation. Other waste materials from the processing of mining substances include overload, which is a waste rock that is removed during mining but unprocessed. Such a material is sometimes thrown into the so -called tip of the prey and left in place.
