Tailings Management - OceanaGold

The management of tailings and the structural integrity of our tailings storage facilities are critical to community safety and environmental protection. Our tailings storage facilities (TSFs) are engineered structures designed and constructed to hold mineral waste (tailings) from our processing facilities. We design, construct and manage TSFs in compliance with all host country regulations ...

Mine Tailings - Mining and Geomorphology

Definition: Tailings are waste stream materials that consists of ground rock and process effluents generated in a mine processing plant through which mechanical and chemical processes are used to extract the desired products from the run of the mine ore (Tailings.info). Extraction and production of Tailings: Different tailings have different compositions based on the composition of the ore ...

Recycling mine tailings in chemically bonded ceramics – A ...

Mine tailings are stored either in dammed ponds along with the process water or as thickened pastes in piles usually near the mine sites. Lottermoser (2010) estimates that approximately 20–25 billion tons of solid mine wastes are produced annually in the world, of which 5 to 7 billion tons are mine tailings ( Mudd and Boger, 2013 ).

Process effluents and mine tailings: sources, effects and ...

Mine tailings, consisting of process effluents that are generated in a mineral processing plant, are generally transferred to tailings ponds/impoundments to meet environmental regulations and site-specific factors before discharge. Most mining activities induce an impact on their geochemical environment (e.g., water, groundwater) due to the ...

The Mining Process - Newmont Corporation - About Us

Once information is back from the lab, we supplement those findings with geologic, geochemical and geophysical data. Understanding the local geology is a very important part of the process, both economically and environmentally. The geology affects mining, processing and the ways in which we manage waste rock, tailings and water.

Mine tailings: How to effectively manage the risk

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 licence to operate. Rather than look at tailings in isolation it actually makes more sense to include it as part of water management.
