Mine Tailings an overview ScienceDirect Topics

Large quantities of radioactive waste and mine tailings are being generated annually worldwide from mining and processing uranium ores for nuclear energy. Radioactive tailings represent a large clean-up challenge to the mining and nuclear energy industries. Therefore in the first few sections of this chapter we detailed the physical, chemical, storage, transportation and disposal of

Managing tailings from mining operations

Tailings differ from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced unprocessed during mining. Tailings are the mineral waste remaining after the processing of ore to extract mineral concentrates and are typically stored within an engineered containment structure known as a tailing storage facility or TSF.

Mine tailings: How to effectively manage the risk

19/08/2020· Tailings should actually be addressed as part of overall water management, as water is the major risk to mining operations beyond just tailings. It requires effective management just to make the operation work cost-effectively. While the tailings risk is unlikely to affect the actual mining effort; a collapsed tailings dam can destroy the mine’s value as well as a company’s reputation and

What are tailings dams? IndustriALL

What are mine 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. They include finely ground rock particles, chemicals, minerals and water. Depending on the type of mining, tailings

Mine Tailings groundtruthtrekking.org

Mine tailings are the ore waste of mines, and are typically a mud-like material. Worldwide, the storage and handling of tailings is a major environmental issue. Many tailings are toxic and must be kept perpetualy isolated from the environment. Scale of tailings production is immense, since metal extraction is usually only ounces or pounds, for every ton of ore. Tailings containment facilities

Tailings Wikipedia

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.. The extraction of minerals from ore can be done two ways: placer mining, which uses water

Risk and the mining industry after the Brumadinho tailings

It’s clear that, in the wake of Brumadinho, tailings dams represent a key existential challenge for the mining industry. A tailings dam failure is a catastrophic event, the effects of which can ripple out from the collapse of the dam itself, leaving a legacy which can endanger the water security of an area for decades to come. Continuing inattention to the risks posed by tailings dams not

Tailingsfo Dry Stacking of tailings

A conventional tailings facility, designed to store water, can provide a mining operation with a buffer (e.g. storm water storage) to maintain operations during dry months of the year. Oxidation of sulphides in the tailings can create high concentrations (but low volume) of seepage water.
