An Assessment of Radiological Hazards from Gold Mine

Jan 18, 2016 The basin has led to a legacy of some 400 km 2 of mine tailings dams (270 tailings dams and 380 mine residue dumps) containing 6 billion tonnes of pyrite tailings and 600,000 tonnes of low-grade uranium [ 9 ]. The gold mining area studied has 5 mine tailings that have been accumulated throughout the operating history of the mine.

A Radiological Survey in Tailings: A Case Study of

Thirty samples of tailing waste weighing 200 g were randomly collected from both active and inactive tunnels at the Rosterman gold mine site in western Kenya. The average activity concentration of the radionuclides (40K, 232Th and 238U) analyzed by the gamma-ray spectrometry in the tailing samples was 260 ± 14.29 Bq/Kg for 40K, 118 ± 8.25 Bq/Kg for 232Th and 81 ± 3.63 Bq/Kg for 238U.

In this article, documented results of natural radionuclide concentrations in tailings at Rosterman gold mine, Kakamega county, Kenya were evaluated. Thirty tailing samples from Rosterman gold mine were collected as per standard sampling procedures and were analyzed for 238U, 232Th and 40K by NaI (TI) gamma-ray spectroscopy. The activities of 238U, 232Th and 40K was found to vary from 39 ± 1

Forgotten Gold Searching Abandoned Mines and Tailings

Witwatersrand gold tailings as a possible uranium resource

Re-mining of Witwatersrand tailings for uranium and subsequent reclamation would not only provide short-term economic revenues, but it would also reduce the likelihood of uranium dispersion into the environment and associated pollution impacts. The presence of substantial uranium contents in wastes of non-uranium mines is an often-neglected fact.
