Factors Affecting Copper Electrical Conductivity: Effect of Impurities

The average brass-founder feels nervous unless his copper is so very pure that it shows a conductivity of 99 or 100 per cent., while the character of the zinc used is usually overlooked in his anxiety. Electrolytic refining has made it possible to produce copper of a very high degree of purity, the metallic impurities averaging but a few ...

Flotation

The electrolytic flotation has mainly been used for small plants with capacity between 20 and 30 m 3 h −1. In dissolved air flotation, the bubbles are produced by controlling the pressure of water saturated with air. Three main processes of dissolved air flotation include vacuum flotation, microflotation, and pressurized flotation.
