Copper Refining - an overview ScienceDirect Topics

In the electrolytic process, copper is electrodeposed to obtain a spongy powder deposit at the cathode rather than a smooth, adherent one. In this feature, it differs from the process of copper refining where a strongly adherent product is desired. Low copper ion concentration and high acid content in the electrolyte favor formation of powder deposits.

CONTINUOUS FIRE REFINING OF BLISTER COPPER

2015-9-7  Development of continuous copper matte converting processes creates a strong demand for continuous copper fire refining. Copper refining requires two stages: oxidation with slagging of impurities and sulphur removal, and copper reduction before anode casting. So, the continuous process needs two reactors or one rector with separated zones.The first continuous refining were in developed at Technical University Berlin [1, 2] based on the principle of separated reverbaratory anode furnace with two zones, where oxidation were carried out by air lances and reduction by lances with reducing flame.The new concept of continuous fire refining is based on the continuous flow of blister copper through two packed bed type reactors. The principle is shown schematically in Figure 1. Blister copper flows into the first reactor filled with ceramic grains, for example grains of a scrap of chromomagnesite bricks. The copper
