Method for extracting rare and precious heavy metals by producing rock wool from red mud and furnace bottom

The invention discloses a method for extracting rare and precious heavy metals by using red mud to produce rock wool and a furnace bottom, and the method comprises the following steps: in the process of producing rock wool from red mud, rare and precious heavy metal elements with the density higher than that of iron and the boiling point higher than 1700 DEG C are naturally settled and enriched in a honeycomb structure of the furnace bottom of an electric melting furnace to form a mushroom-shaped mixture, and then the mushroom-shaped mixture is taken out; and carrying out iron removal and classification treatment. In the process of producing the rock wool through comprehensive utilization of the red mud, rock wool series products with high additional value can be produced, meanwhile, unnecessary rare and precious heavy metal elements in redundant rock wool fibers in the red mud can be naturally enriched, and the requirements of national policies, energy conservation and environmental protection are met. 本发明公开
