Massive stockpiles of uranium (U) mine tailings have resulted in soil contamination with U. Plants for remediation low extraction efficiency Chelating agents can mobilize U soils and, hence, enhance phytoextraction from the soil. However, rapid mobilization rate by chelating a short period than plant uptake could increase risk groundwater soluble leaching down profile. This review summarizes re...

Flotation tailings from copper production are deposits of copper and other valuable metals, such as Mo, V and U. New hydrometallurgical technologies are more economical and open up new possibilities for metal recovery. This work presents results of the study on the extraction of copper by mixed extractant consisting p-toluidine dissolved in toluene. The possibility of simultaneous liquid-liquid...

Tailings are mine wastes in the form of slurries stacked in mine sites abandoned after the exhaustion of ores. There are approximately 5000 abandoned mine sites in Korea, and tailings have become a serious environmental problem. Long-term environmental exposure of tailings can cause release of acidic and high concentrations of sulfate- and metal-contaminated water (acid mine drainage, AMD). Org...

Mining tailings represent a generating source of rich heavy metal material with a potential danger the public health and the environment, since these metals, under certain conditions, can leach and contaminate aqueous systems that serve like supplying potable water sources. The strategy for this work is based on the observation, experimentation and the simulation that can be obtained by binding...

Effects of Low-Level Chronic Radiation on Plant Nuclear Parameters as Related to Successional Patterns by Eric A. Rechel, Master of Science Utah State University, 1977 Major Professor: Dr. W. F. Campbell Department: Plant Science vi A major i ss ue facing nuclear power stations is how to effectively deal with radioactive waste. This waste, as it comes from a reactor, is emitting large quantitie...
