RESEARCH ON THE REMOVAL OF RADIUM FROM
2002-6-21 Keywords: Uranium, Radium, Uranium effluent, Aeration, Hydrated manganese hydroxide, Adsorption 1. INTRODUCTION A significant quantity of uranium effluent can be produced during uranium mining and milling operations. The natural radionuclide radium is a normal element existing in uranium effluent. It can have a great influence on the environment.
Uranium, thorium, and protactinium in a manganese
Isotopic compositions of uranium, thorium and protactinium have been determined in a manganese nodule dredged from the North Pacific Ocean. Both the 230 Th and 231 Pa activities are found to decay exponentially with depth in the nodule.
Thorium and uranium isotopes in a manganese
Thorium- and uranium isotopes were measured in a diagenetic manganese nodule from the Peru basin applying alpha- and thermal ionization mass spectrometry (TIMS). Alpha-counting of 62 samples was carried out with a depth resolution of 0.4 mm to gain a high-resolution 230 Th excess profile. In addition, 17 samples were measured with TIMS to obtain precise isotope concentrations and isotope ratios.

Manganese removal and uranium recovery from acid
The acid water sample BIA which presented the highest uranium (12 15mg/L) and manganese content (173mg/L) along with a very high content of iron (180mg/L), was used in the adsorption assays. From the adsorption isotherms and the continuous column experiments, it was possible to determine the uranium and manganese loading capacity of the most
Manganese biomining: A review PubMed
Biomining comprises of processing and extraction of metal from their ores and concentrates using microbial techniques. Currently this is used by the mining industry to extract copper, uranium and gold from low grade ores but not for low grade manganese ore in industrial scale. The study of microbial
In situ effects of metal contamination from former
2016-6-7 Other trace metals (e.g., iron, manganese, copper, cadmium, and zinc) are also found in former uranium mining areas, either due to their natural presence or to extraction and effluent treatment processes (Pereira et al. 2008).
Uranium, thorium, and protactinium in a manganese
Isotopic compositions of uranium, thorium and protactinium have been determined in a manganese nodule dredged from the North Pacific Ocean. Both the 230 Th and 231 Pa activities are found to decay exponentially with depth in the nodule. The corresponding accretion rate of the nodule, averaged over the past several hundred thousands of years, is about 4 mm/10 6 y.
