Abstract
Anodes containing non-ferrous and precious metals are cast from the metal phase supplied to electrical enterprises after sorting by individual elements. The article deals with the main aspects of determining the dissolution potentials of copper and nickel alloys containing precious metals in laboratory conditions and the choice of electrolyte for their dissolution. The chemical composition of the investigated anode is given. Graphs of time and voltage dependence of the obtained potentials are given. The influence of some impurities on the process is explained. The conclusion about rationality of the use of salt electrolyte is made.
