Tailings are a by-product of mining. After ore containing an economically-recoverable commodity is mined from the earth, that commodity is extracted in a processing plant or mill. After the commodity of value is extracted from the ore material, the resultant waste stream is termed "tailings". Typically, mill tailings range from sand to silt ...

· Only 14% mined material makes it to processing for metals. Tailings are what is left over after mills separate the metal from the mined rock. The processed material "tailings" comes from the "tail" end of a mining mill and comprise fine particles mixed with water forming a slurry. Mining companies will store this waste in dams or ponds.

· The heat treatment or the annealing process of producing stainless steel often causes a scale or build-up on the steel. Several steps are taken to get rid of the scale, through a process known as descaling. One of the methods involves pickling, where a nitric-hydrofluoric acid bath is used to remove the scale.
