Production of the Calcium Fluoride From Solid and Iiquid Wastes of Aluminum Production Process

A technology for the regeneration of яuorine to produce calcium яuoride from a saturated solution of gas puriёcation had developed. Investigated the optimal conditions for the synthesis of calcium яuoride gas cleaning solutions. Production of calcium яuoride will reduce the cost of secondary cryolite, and the purchase of a primary CaF2 to 80 %. The laboratory study on extraction of яuoride from solid waste leaching process followed by obtaining secondary яuorides. Waste technology will reduce the waste of aluminum production, to receive income from the use of recycled materials and implementation of carbon concentrate in other industries.
