  • Recovery of Gold and Silver from Secondary Sources of

    Fine materials, such as flue dust, generated during processing of electronic waste (ewaste) contain valuable metal resources, such as Au and Ag However, recovery of valuable metals from this flue dust has not been extensively studied In this study, a leaching process was investigated for effective recovery of Au and Ag from flue dust In particular, thiourea was used as leaching reagent toIn 1973, a pressure stripping method, which decreased the time needed for the stripping step, was developed to desorb gold and silver from carbon An alcohol desorption method, developed in 1976, also decreased the carbon stripping time InRecovery of Gold and Silver from Ores byRecovery of Gold and Silver and Removal of Copper, Zinc and Lead Ions in Pregnant and Barren Cyanide Solutions Gabriela Figueroa1*, Jesus L Valenzuela1, Jose R Parga2, Victor Vazquez1, a novel method for the minimization of heavy metals in the wastewater from the mining industryRecovery of Gold and Silver and Removal of Copper, Zinc
