Anodic oxidation of iron during the purification of sulfate zinc solutions

The anodic oxidation of iron in zinc solutions is carried out using a two-chamber electrolyzer separated by an anionite membrane. The positive effect that copper ions in the solution have on the rate and completeness of the oxidation processes is shown. This method is effective for cleaning the solutions of zinc production and processing the industrial zinc-containing wastes.

Computer simulation of microcomposite ceramics with high transcrystalline mobility

Computer simulation is used to consider the possibility of creation of microcomposite technical ceramics with a high transcrystalline mobility and to show that allowance for the exchange interactions of atoms through nonequilibrium electrostatic fields causes formation of self-organized mesoscopic (SM) blocks, which provide microplasticity and relaxation of strain at lower temperatures. The simulation results agree with the yield stria observed in mechanical compression tests of A1₂,O₃ specimens obtained from sol-gel solutions. It is shown that the yield stria are directly connected with the sizes of the SM blocks. The high mobility of SM blocks also promotes a decrease in the temperature of the gel → A1₂O₃ transformation.     

Leaching of lead cakes of zinc production in a complexing solvent

The process of leaching of lead cakes of zinc production in a complexing solvent—trilon B, which makes it possible to selectively extract lead into the solution—is studied with the use of mathematical modeling of the experiment. Its optimum conditions—pH, liquid-to-solid ratio within pulp, and temperature—are determined. The developed flow chart of cake processing provides zinc removal as a single product, recycling of zinc to the basic production, and reduction of current expenditure due to solvent regeneration.
