In 1915, they established the Schlesinger Radium Company plant in Denver. Walter Koenig was plant manager and Henry worked on radium paint. C. F. Whittemore, from the US Bureau of Mines, later joined the company as chief physicist. Mineralogist Karl L. Kithil, .
Radium, as well as it's daughter radon, are naturally occurring elements found in uranium and thorium ores. Another major source for these radioactive pollutants is the waste from oil and gas industries.

Radium is a very rare metal and hasn't its own minerals; radium is a decay product of U and Th and exist in very low concentrations in uranium and thorium ores.
Natural uranium is transported as uranium oxide after it is refined at the mining site. It is not very radioactive, much less radioactive than the ore from which it .
Mar 31, 1987· The removal of radium from acidleached uranium mill tailings has been difficult due to its strong retention as mixed sulfates and in adsorbed forms.

Uranium decays into radium and radon gas, and other "daughter" products. Over hundreds of thousands, or millions, of years, these decay products build up and contaminate the water in and near the ore body. For example, the EPA has a proposed maximum level for radon gas of 300 pCi/L in drinking water.
Radium removal from Elliot Lake uraniummill solids by EDTA leaching. Hydrometallurgy, 10: 173175. Ethylenediaminetetraacetic acid (EDTA) in alkaline solution has been found to be effective in the extraction of radium226 from uraniummill final Pachuca solid discharge at Elliot Lake, Ontario.
Mar 31, 1987· The removal of radium from acidleached uranium mill tailings has been difficult due to its strong retention as mixed sulfates and in adsorbed forms. With this invention the leaching action of a complexing agent (reducing the free radium cation concentration in solution) is combined with that of a .
