Electrowinning

Electrowinning, also called electroextraction, is the electrodeposition of metals from their ores that have been put in solution via a process commonly referred to as leaching. Electrorefining uses a similar process to remove impurities from a metal. Both processes use electroplating on a large scale and are important techniques for the

Titanium Anode In Electrolytic Extraction Of Metal

titanium anode in electrolytic metallurgy. Electrolytic extraction of non-ferrous metals can be carried out in the chloride electrolyte, sulfate electrolyte and chloride sulfate mixed electrolyte. It requires a good stability of anode, corrosion resistance, a long lifespan and a good electro catalytic activity to reduce the anode reaction over potential and tank voltage. It is difficult to

Electrolytic Cell

The electrorefining of many non-ferrous metals is done with the help of electrolytic cells. Such electrochemical cells are also used in electrowinning processes. It can be noted that the industrial production of high-purity copper, high-purity zinc, and high-purity aluminium is almost always done through electrolytic cells.

Electrowinning of cerium group metals from fused chloride bath

Electrowinning of cerium group metals 159 at 7 and 7.6 A/cm ~ respectively, a decrease in CE is observed with further increase of CCD. The possible reason for decrease of CE at very high CCD is co-reduction of solvent ions at cathode.

Electrolytic cell

An electrolytic cell is an electrochemical cell that uses electrical energy to drive a non-spontaneous redox reaction. It is often used to decompose chemical compounds, in a process called electrolysis—the Greek word lysis means to break up. Important examples of electrolysis are the decomposition of water into hydrogen and oxygen, and
