The Use of Flotation for Treatment of Anthropogenically Impacted Soils

The study is devoted to the remediation of contaminated soil with the presence of potentially toxic elements by flotation. The research summarizes the results concerning the verification of the effectiveness of selected flotation agents at different doses. Kerosene and potassium ethyl xanthogenate were used as reagents. Application of these two reagents simultaneously and flotation without the use of a collector were also tested. The flotation tests showed that similar results were obtained with kerosene, which is a non-polar collector, as with the polar potassium ethyl xanthogenate, which as an anionic collector is designed specifically for metal flotation. Interesting results were also achieved in flotation without the use of a collector.
