Mechanism of flotation process
Soil washing is a process in which water, with or without additives, mixes with contaminated soil and debris to produce a slurry feed. This feed enters through a scrubbing machine to remove contaminated fine soil particles (silts and clay) from granular soil particles. Radionuclides are generally bound more tightly to the fine soil particles and not to larger grained sand and gravel. It is well known surfactant molecules is contained hydrophobic and hydrophilic regions. The combination of hydrophobic and hydrophilic properties in the same molecule gives these species unique solubility properties in water or aqueous media. In dilute aqueous media, surfactants molecules usually exist as monomers. Aggregation of these monomers in different forms called micelles and changes of physical properties of the solution occur at a surfactant concentration known as the critical micelle concentration. These media which contain micelles have been shown to exhibit some interesting features. They are capable of solubilizing many water-insoluble substances within and on the surface of the micelles (Ahn et al., 2008; Mulligan et al., 2001, 1999). The effective removal of radium species from TENORM scale can be explained by the increased solubility of radium …show more content…

Generally, the change in the concentration of surfactant is leads to change in their physical properties such as micelles formation and its solubilization effect for radium species present in TENORM waste (Mulligan et
