Abstract

The article presents the results of a study to determine the optimal conditions for an autoclave desiliconization of a zinc product. According to the plan of a six-factor experiment at 5 levels, the optimal conditions for the process of leaching of silicon dioxide from a zinc product were determined. Based on significant partial dependencies, a generalized multivariate equation was compiled for the degree of extraction of silica in solution. The generalized multifactor equations make it possible to determine the optimal conditions for the desiliconization of a silica-containing zinc product with a combination of different temperatures, the duration of the process, and the initial alkali concentration in the solution.
