EVALUATION OF THE POSSIBILITY OF PHYTOSTABILIZATION OF POST-FLOTATION TAILING PONDS

The effect of organic fertilization and microbiological preparations for phytostabilization of copper ore tailings were examined. It has been shown that the introduction of the pulp, waste from the sugar industry, leads to the mobilization of trace metals. The copper content in aqueous extract of enriched waste was greater than 500-fold higher than in controls. It has also been stated an increase in the toxicity of extracts. While the use of biopreparations for seed treatment contributed to the stimulation of nutrients uptake by plants. In the biomass of plants from treated seeds with a suspension of Azotobacter strain EK, and biosurfactant was found more phosphorus and calcium than in plants from control.
