Operation Characteristics of the Series System for Electrolytic Refining of Copper

In the copper electrolytic refining operation, two main objectives are desired: the first is the production of a metal of desired chemical composition and physical characteristics, and the second is the recovery of the valuable by-products.

The Characteristics of the Electrolyte in the Series System of Electrolytic Copper Refining

Almost everyone is familiar with the tremendous importance of copper in our everyday life. One of the pro­perties of copper which determines its great usefulness to mankind is its electrical conductivity. This property alone has more to do with the prominence of copper among useful metals then does any other.

Separation of Cadmium from Zinc in the Purification Step of the Leaching Cycle

The purpose of this investigation is to determine the effect of the factors listed previously by conducting a series of tests that will indicate the ex­tent to which the purification is influenced by time, temperature, zinc oust size, zinc dust quantity, iron concentration, two stage precipitation, and aeration.
