Tailings and Waste Rock Clean Environment Cameco

Tailings and Waste Rock. Mining at our operations in northern Saskatchewan requires the excavation of rock to access the uranium bearing ore. This waste rock is classified as either mineralized or non-mineralized. Waste rock generated during underground mining is temporarily stored underground before being moved to surface for storage.

Prospecting Gold Tailing Piles with a Metal Detector

Most dredge tailings are absolutely littered with iron trash, from square nails and boot tacks, all the way up to 55-gallon oil drums! The old-timers just didn’t give much thought to littering, and it is clearly evident once you start swinging your detector across some tailing piles.

Gypsum Tailings Vinland Materials

The Flat Bay mining district, in St. George’s, Newfoundland and Labrador, is composed of several abandoned gypsum mines that historically produced high quality gypsum to supply the wallboard industry. As a result of this high-grading process, a very large gypsum tailings pit developed from years of screening and washing.

Tailingsfo What are tailings? Their nature and production
IntroductionNature of TailingsProduction of TailingsTailings CharacteristicsTailings 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. This process of product extraction is never 100% efficient, nor is it possible to reclaim all reusable and expended processing reagents and chemicals. The unrecoverable and uneconomic metals, minerals, chemicals, organics and process water are dis...

Left behind after operations ceased were underground mine workings, waste rock dumps, piles of mine tailings, and an open mine pit. In addition, historic mining activity at the site fractured the mountain, exposing minerals in the mountain to surface water, rain water, and oxygen. When pyrite is exposed to moisture and oxygen sulfuric acid

All three gypsum stacks constructed or proposed since the enactment of the 1993 Florida Phosphogypsum Management regulations have followed or exceeded the Florida standards but none of the designs approach the protectiveness of the uranium mill tailings standards. The Plant City gypsum stack proposal goes beyond the Florida standards due to the

Environmental Risks From Mine Tailings

Aug 10, 2018· Slumps, landslides.Tailing piles can be unstable, and experience landslides. In 1966, in Aberfan, Wales, a hill of mining debris famously collapsed onto buildings, resulting in 144 deaths. There are also cases where wintertime avalanches occurred on tailings, with loss of life for residents below.

Mine tailings dams: Characteristics, failure

Within tailings piles there is an increase in bulk density with depth as the result of compaction, dewatering and diagenesis. Sarsby (2000), for example, gives a gradient of 0.09–0.17 t m −3 per 30 m depth change. The froth flotation process utilizes flocculants to render targeted metal cations hydrophobic in order that they may be

Stockpiles, Tailings and Spoil Contaminants in Drinking Water

Tailings Tailings are low grades of mining ore that are disposed of on the land surface and often in mining waste ponds(1). Because they are unlined, these ponds can be a source of acids or metals, which are carried in run-off or leachate. Spoil Spoil consists of mining debris and waste.
