Scientific novelty
The method utilizes inexpensive and accessible mining waste, specifically aluminosilicate materials generated during the extraction and processing of loparite ore. The primary innovation lies in the activation of the waste by applying 1% calcium fluoride to its surface, creating an effective seeding material for fluoride precipitation. This accelerates the purification process and achieves a high degree of fluoride removal without complex chemical processes or expensive reagents.
Advantages
1. Cost-effectiveness: production waste is used instead of purchasing expensive reagents, reducing treatment costs. 2. High efficiency: the method reduces fluoride concentration in water to a safe level (less than 1 mg/l) even at high initial concentrations. 3. Ease of use: no strict acidity (pH) control or complex equipment is required. 4. Reuse: the resulting sludge can be reused to treat new batches of water, reducing waste volume. 5. Environmental friendliness: the method uses no toxic substances and helps recycle mining waste.
Commercial implementation
The technology can be implemented at enterprises generating wastewater with high fluorine content: mining and processing plants; metallurgical plants; chemical production (e.g., production of fertilizers, aluminum, glass); rare metal processing enterprises. The method is suitable both for tertiary treatment before discharge into water bodies and for organizing closed-loop water cycles at production sites. The solution can be offered as ready-made units or reagent modules easily integrated into existing treatment systems.
