What is the purpose of tailings?

Tailings are the waste products from mining. Mechanical and chemical processes are used to grind up rock into a fine sand to extract the valuable mineral or metal from the rock ore. All the unrecoverable and uneconomic remnants from this process are waste.

What is a tailings pile?

Tailings are a type of rock waste from the mining industry. When a mineral product is mined, the valuable portion is usually embedded in a rock matrix called ore. Once the ore has been stripped of its valuable minerals, sometimes through the addition of chemicals, it is piled up into tailings.

How tailings are formed?

Tailings consist of ground rock and process effluents that are generated in a mine processing plant. Mechanical and chemical processes are used to extract the desired product from the run of the mine ore and produce a waste stream known as tailings.

What are tailing piles?

What are mine tailings made of?

Mine tailings are usually produced from the mill in slurry form, which is a mixture of fine mineral particles and water.

What chemicals are in tailings?

Tailings from oilsands can contain napthenic acids, polycyclic aromatic hydrocarbons, phenolic compounds, ammonia, lead, mercury, and other metals.

What are tailings in construction?

Tailings is a common by-product of the process of extracting valuable minerals and metals from mined ore. Tailings storage facilities follow one of three wall construction designs: these are downstream, upstream and centreline. Downstream. Downstream designs start with an impervious starter dam.

Can iron ore explode?

Iron ore spreads explode as mills rush to grab higher grades.
