Изучена проблема загрязнения водных ресурсов фторидами применительно к Ловозерскому ГОКу, где концентрация фторидов в стоках превышает допустимые нормы в 20–37 раз. Существующие методы очистки имеют существенные недостатки. В качестве альтернативы предложен метод химического осаждения с использованием солей кальция и затравочных материалов на основе промышленных отходов. Эксперименты показали, что нанесение слоя CaF₂ на эти материалы ускоряет процесс осаждения и повышает эффективность очистки до 98,4 %. Разработан критериальный метод оценки материалов, учитывающий стоимость, скорость осаждения, доступность и необходимую массу затравки. Наиболее перспективными признаны хвосты обогащения и пустая порода, что позволяет снизить затраты и утилизировать отходы производства. Метод обладает потенциалом для масштабирования и внедрения на промышленных предприятиях.

Работа выполнена в рамках госзадания Министерства науки и высшего образования РФ FSRW-2024-0005 «Новые подходы к проведению экологического мониторинга арктических экосистем, подверженных влиянию объектов минерально-сырьевого комплекса, и разработка технологий их комплексного восстановления».
