Remediation of Radium from Contaminated Soil

Remediation of Radium from Contaminated Soil

The stirrer and air recharge pipe of the Denver flotation machine were uninstalled and replaced with a larger stirrer. A cell, which has a larger height and a smaller bottom length and width, replaced the flotation cell, and plastic film was used to seal the top when the slurry was put into the cell. The volume of the cell was 1 liter.
