TENORM: Copper Mining and Production Wastes Radiation

Mining and Processing MethodsWaste GenerationDisposal and ReuseEPA and The StatesCopper mining wastes make up the largest percentage of metal mining and processing wastes generated in the United States. There is a broad range of TENORM concentrations in copper mining wastes. Mining and extraction of copper by surface or underground methods can concentrate and expose radionuclides in the waste rock and tailingstailingsThe remaining portion of a metal-bearing ore after some or all of a metal, such as uranium, has been extracted..

Economic Potential for reprocessing Copper Mine Tailings

Four copper mine tailings in Chile were investigated for their elemental and mineral composition, in order to evaluate the potential for economic reprocessing. The sample material, taken for processing had Cu-contents between 0.1 and 0.5 %. Copper was abundant in various primary (mostly chalcopyrite) and secondary (cuprite, atacamite, b

Copper Tailing an overview ScienceDirect Topics

The copper tailings were used at 20% content as a fine granite replacement for fraction size smaller than 1.18 mm. The aggregate grading of the copper tailings mix was kept similar to the reference mix, thus the difference in aggregate packing between the two mixes was kept to a minimum. In the same study, the effects of bitumen characteristics

Copper tailings: if the copper with high heavy metals content, the separation will be easier and apply the process of flotation. If there exist magnetite in the copper tailings, it will firstly using acid leaching to precipitate the copper, then use magnetic separation accordingly.

Environmental Risks From Mine Tailings

Aug 10, 2018· Tailings from copper and uranium mining often produce measurable levels of radioactivity. Tailing Ponds Some mining wastes become very fine after they have been ground up during processing.

Geotechnical Properties of Mine Tailings Journal of

Therefore, the consolidation process of the fine iron tailings during and after the construction of the tailings dam can be analyzed with the traditional Terzaghi’s theory, whereas for the fine copper tailings, the acceleration of the consolidation process caused by the increase in C v should be considered.

May 15, 2017· Mine tailings may contain base transition metals, such as iron, copper, nickel and zinc, in relatively high concentrations, and also occasionally precious metals such as gold and silver, in minerals (and native metals) that have been not been separated by froth flotation (e.g. Bryan et al., 2006, Ahmadi et al., 2015).

From Tailings to Treasure? Miners Make Advancing Mining

Mintails, a mine tailings processor, has developed new technology to process 350,000 tons of slimes from its extensive tailings resources. It expects to recover 58 kg of gold per month, and has enough slimes to last until 2025.

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 discharge
