Abstract
A method for obtaining aluminium and other metals by electrolysis with pool cathode and horizontal anode. To increase the efficiency and ecological purity of the process the level of the electrolyte is maintained at one to two times the interpole gap. Raw material feeding to the electrolyte is effected by means of vertical movements of the anode.

A decrease in the elec- tricity level for one or two values of ΜΜ reduces the speed of 5 electroprocesses that cause emulsification of the metal.

Alumina in this case was lost in the elec- trozer through a gap formed between a small 5-gas and small gas furnace, as well as in small ones. The developed irregularities and the plots of the disturbances of the hermetic siphoned off alumina. The frequency of anode effects on fresh baths during the week of testing was 0.25 per day in the middle of the bath per day, and 1.7 on the main baths, which is very high. There were no cases of accumulation and formation of plantings on the back. The supply of alumina to all the use of the anode makes it possible to work with weekly low levels of 15 electorate.
