Electroleaching of Copper Waste with Recovery of Copper by Electrodialysis
A new process to leach and recover copper from solid waste using electric fields was designed. The leaching with electro migration is presented as an alternative to traditional leaching. Preliminary data indicate that the copper ion migration is facilitated by using the electrical potential difference; therefore applying a potential difference in the processes of leaching facilitates the remova...
متن کاملThe Recovery of Soluble Copper from an Industrial Chemical Waste
A novel electrochemical device was used to recover copper metal from an inorganic chemicals process effluent. In a sidestream pilot-plant demonstration, the copper content was continuously reduced from an average of 20 mg/l to less than 2 mg/l. The basic concepts, laboratory testing, and pilot-plant demonstration are described. General Future water-pollution regulations may require effluent con...
متن کاملELECTROLYTIC RECOVERY OF COPPER FROM CHELATED WASTE STREhMS
Electroless plating is a chemical reduction process which depends upon the catalytic reduction of a metallic ion in an aqueous solution containing a reducing agent without the use of electricity (1). Cahill (2) showed that the cupric ion could be reduced autocatalytically with formaldehyde in an alkaline solution. Okinaka (3 ) established that the overall reaction of the catalytic copper platin...
