Abstract
The process of carbonization of aluminate solutions is one of the main in the hardware and technological schemes of alumina production from nepheline and low-grade bauxite. Total energy costs for this process are determined by the power consumed by agitating devices and spent on gas supply to the apparatus. The value of the latter depends on the hydraulic resistance of carbonizers and gas flow rate. Varying geometrical parameters of the mixing device and liquid level in the apparatus, we were able to select the best operating modes of carbonizer, as well as to study the effect of gas speed and speed of the mixing device on the mass transfer coefficient.
