Electro winning, also called electroextraction, is the electro deposition of metals from their ores that have been put in solution via a process commonly referred to as leaching. Electro refining 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 electro won.
The metals that can be recovered by this method are copper (Cu), nickel (Ni), zinc (Zn) and cobalt (Co), and used in the recovery of cyanide-based electrolytes of gold (Au), silver (Ag), copper (Cu), zinc (Zn) and cadmium (Cd) - cyanide is electrochemically destroyed, due to the enhanced anode efficiency. Different metals plate out at different voltages so application if the different voltages will allow all metals to be recovered from a mixed metal effluent.
Tiaano manufactures Platinised Titanium Anodes which have gained acceptance in the Metal Electrowinning Industry. Platinised Anode technology has all but replaced lead anodes as the anodes of choice with industries becoming more environmentally conscious. Platinized Anodes offer a cleaner alternative and significant power savings over lead anodes. Platinum is a precious metal, having very good physical and chemical properties, such as high corrosion resistance, thermal conductivity, and catalytic nature. As it is very expensive, platinum cannot be used in its solid form as an anode. So that Platinized Metal Anodes (Pt Anode) are produced by electroplating platinum (Pt) on a specially treated precious metal (Titanium / Niobium) substrate by means of electro deposition process. Electroplated metal anodes are economical as well as it retains the superior physical and chemical properties of platinum.
Our Platinised Titanium Anodes have a proven track record in applications such as:
Electroplating, Electro Winning or electroextraction, Electrosynthesis, Electrodialysis, Drinking Water electrolysis, Cathodic Protection, Sodium Hypochlorite, HHO Generator, Swimming pool disinfectant, Perchlorate protection, Chlor-alkali industry etc...
Due to our proven plating technology, Tiaano Platinised Titanium Anodes have become the anodes of choice. Tiaano Platinised Anodes Electrodes results in platings which provide the following attributes:
• Higher levels of adhesion of the precious metal plating
• Better uniformity of plating
• Greatly improved resistance to acid attack
• Resistance to interface degradation by deposits
