What You Need to Know about 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 economical and straightforward purification of non-ferrous metals. The resulting metals are said to be electrowon metals. In electrowinning, a current

How Polarity Reversal Affect the Lifetime Of Ruthenium and Iridium Tantalum Coated Titanium Anodes The current density, sodium chloride concentration, and current reversal cycle length can affect the polarity reversal of coated titanium electrodes.   For ruthenium and iridium tantalum coated titanium anodes, the lifetime increased with decreasing current density or decreasing reversal cycle frequency. NaCl had no effect on lifetime over the 180 range studied. The effect of anodic and cathodic current density indicated that i

How Reversed Electrodes are Used for Hard Water Treatment? In water treatment process, calcium and magnesium deposits build-up on the cathode. Over time, the deposits can cause increases in the operating cell voltage, thus decreasing cell efficiency. Various techniques have been proposed for the removal of the cathode scale deposits from hard water treatment systems. The technique of polarities of the electrodes are periodically reversed in the hard water treatment system is used commercially though it has its own challenge

How Coated Titanium Electrodes are Used in Electrochemical Water Disinfection Coated titanium anodes have been used for electrochemical water disinfection of domestic (drinking and swimming pool chlorination) and industrial water. The disinfecting agents like hypochlorite ions and hypochlorous acid can be generated on-site in the electrochemical process, which avoids the storage and transporting of hazardous materials like chlorine gas. Electrochemical water disinfection is based on the chloride content in the water to generate
