Solutions for the uranium mining industry

Waterfowl landing in cyanide or sulfuric acid leach ponds is a serious environmental concern. Waterfowl are naturally drawn to the reflection of light off of water bodies and can land in any pond regardless of where or how long it has been established. USDA Wildlife Service studies have shown that by reducing aerial visibility to ponds, waterfowl will not be attracted to the water. The Saturn Disc provides a 99% total eclipsing of the sun covering ponds of any size.

Uremediate soil and water remediation of Uranium

Please see files for more information. The following mechanisms of direct bacteria-uranium interactions are described: i) oxidation of U(IV) to U(VI) resulting in solubilization; ii) bioaccumulation, which includes processes of bio-sorption by cell surface iii) reduction of U(VI) to insoluble U(IV); polymers and/or uptake inside the cells. iv) The U(VI) accumulated both on the bacterial surfaces or inside the cells as well as biologically reduced U(IV) precipitates can initiate bio-mineralization processes,...

Phosphorimetric determination of uranium in water

Introduction The presence of uranium in water causes radiological pollution as all uranium radionuclides decay by both alpha and gamma emissions. Chemical aspects of uranium toxicity include mainly nephritis and other renal diseases. Mentioned harmful features affect on humans even in low concentrations thus requiring sensitive analysis methods.

Water Treatment Solutions for Uranium Removal

AdEdge provides treatment systems for for Uranium removal using AD92 an anion exchange media that is ideal for use in potable water as well as non-potable and environmental remediation applications for removal of naturally occurring uranium. The high efficiency AD92 can selectively remove the negatively charged uranium anion (most often in the form of uranyl carbonate) to below the existing EPA MCL of 30 ug/L. The AdEdge AD92 systems can deliver the needed performance in two ways: (1) via regeneration type...

Industrial water Uranium recovery & purification

The type of Uranium mineralization and the nature of its association within a particular deposit will have a major impact on process route selection. Uranium minerals are classified according to their influence on extractive metallurgy. The presence of impurities such as Vanadium, Molybdenum, and others may dictate that ion exchange is to be employed.

Water Treatment Solutions for Radium Removal

Radium is found naturally in uranium ores. It is an alkaline earth metal that decomposes in water and it is over a million times more radioactive than the same mass of uranium. As a radiological hazard that emits alpha, beta, and gamma rays, it is a carcinogen.

Radiation and chemical detection instrumentation for Mining & drilling

Mining and drilling operations for radioactive ore such as Uranium, Thorium, Radium, and Rare Earth requires detection and monitoring of radionuclides. Drilling for gas or oil using hydrofracking methods also requires radiation monitoring for environmental and worker safety. Fracking rock releases naturally occurring radioactive isotopes such as Radon, Radium-226, Uranium-238, and Thorium-232. Equipment used for prospecting oil, water, or gas requires the use of radiation detectors for geological evaluation. US...

Zero valent iron nanoparticles for water treatment and purification

All described properties of Fe(0) nanoparticles can be even used for decomposition of pollutants contained in the waste water, mainly for treatment of industrial sewage and hutch water. The usage of nanoiron can represent a significant qualitative step in the classical technologies of water treatment including drinking water. The extremely reactive iron nanoparticles thus offer a possibility to solve long-lasting problems with a high content of uranium and arsenic in a variety of localities in the Central Europe....
