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 کاملMortality from Copper Smelter Emissions Circa 1967
Pope et al. (2007) found lowered monthly mortality rates during a 1967–1968 copper smelter strike, coincident with and attributed to widespread reduced airborne sulfate levels. The authors cited three “intervention” studies associating particulate emissions reductions with mortality reductions as supportive. Evidence below suggests that mortality reductions in the study by Pope et al. and “inte...
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...
متن کاملStudies of morbidity near a copper smelter.
Children living near a copper smelter in Tacoma, Washington, have been shown to have increased levels of urinary and hair arsenic. Studies of hearing, blood status and school attendance in exposed and nonexposed children failed to detect any differences in these parameters.
