New type MMO anode and Lead Dioxide(PbO2) coated Titanium Anode for Electrowinning of Copper, Nickel, Cobalt; 

This electrode use titanium mesh as substrate, and coated with Mixed Metal Oxide(MMO, no Iridium) or Lead Dioxide(PbO2);  Comparing with lead alloy anode, have advantages as following： 1, High purity of cathode copper or other products. 2, Lower power consumption. 3, Endure high concentration of chloride, fluoride ions... 4, Longer service lifetime than lead anode. 5, No Anode sludge produced. 6, No secondary pollution to the cathode copper or other products. 7, Light weight, save labor cost.

Dear Kavin,

Acid mist control has been a severe problem in copper electrowinning operations around the world. The problem is becoming more relevant under the actual and future scenarios in which the production of copper using this route has increased dramatically in the last years. This in combination with environmental regulations are demanding the industry to explore for a definitive solution. The control of acid mist in Copper Electrowinning tankhouses produces a series of benefits such as: reduced corrosion of the buildings, savings in electrolyte heating needs, improves worker’s confort, etc. An important extension of the benefits introduced by the proper capturing and collection/cleaning of acid mist is the associated mechanization of the operations.

Capturing the mist in existing plants allows marginal expansions using same cells and electrodes, provides the electrometallurgical parameters are maintained under control. Additional cells are not needed.

Hope it is helpful to you.
