Recovery of metals from chloride leach solutions of anode ...A separation process was developed to recover Au(III) from the chloride leach solution of anode slime using selective extraction and stripping step. The anode slime contained Ag, Au, Cu, Ni, Sn and Zn. The extraction with Cyanex 272 in kerosene was conducted by varying the HCl concentration of the solution from 0.5 to 9 M. Most of Au(III) and Sn(II) were extracted into .HYDROMETALLURGICAL PROCESSING OF ANODE SLIMES .Hydrometallurgical Processing of Anode Slimes Obtained from the. 67 Figure 3.

The characteristic EDX spectra of the anode slime produced in 3h with 1000 A/m2The treatment of copper refinery anode slimes | SpringerLinkThere are numerous viable approaches to the treatment of anode slimes from electrolytic copper refining. Of particular interest in the treatment of slimes are the behavior and recovery of selenium. The understanding of the process chemistry involved in the treatment of anode slimes should be aided considerably by recent work on the formation and characterization of slimes.A Novel Process For Recovery Of Te And Se From Copper ...settle to the bottom of the electrolytic cells. Anode slimes almost invariably contain copper, tellurium, selenium, silver, gold and traces of platinum group metals. In order to recover the precious metals from slimes, refineries must first complete the separation of copper, tellurium and selenium prior to refining silver and gold to pure products.

C. Whereby lead dissolution is maximized and other metals are minimized. Separate the leach solution from the undissolved slime residue, crystallize lead from the separated .

CHARACTERIZATION OF ADHERENT ANODE SLIMES IN .

anode slimes that adhere to the anode's surface are referred to as adherent anode slimes. The formation of adherent anode slimes can inhibit the dissolution of the anodes. If the dissolution reaction is completely inhibited, the anode passivates (Moats & Hiskey, 2010). The anode passivation causes the process to be inefficient (Cheng ...Recovery of Gold and Silver from Copper Anode Slime ...This study has shown that gold and silver can be recovered from a complex anode slime containing copper, selenium, and tellurium, but a carefully planned leaching procedure is required. To extract the gold with thiourea, it is necessary to first remove the copper, selenium, tellurium, and most of the silver from the mixture. Once these elements are removed, the gold and most of the remaining ...HYDROMETALLURGICAL PROCESSING OF ANODE SLIMES .Hydrometallurgical Processing of Anode Slimes Obtained from the. 67 Figure 3.

The characteristic EDX spectra of the anode slime produced in 3h with 1000 A/m2Recycling of copper telluride from copper anode slime ...Efficient separation of tellurium and copper from copper telluride was achieved through a pressure oxidizing alkaline leaching process under the optimal conditions of 5 mol/L for NaOH concentration, 5:1 for liquid to solid ratio, 150 °C for temperature, 0.7 Mpa for system pressure, and 2 h for reaction time, by which over 95% of tellurium was ...Process for the Recovery of Gold from Anode Slimes ...Jan 25, 2018· The general process for the hydrometallurgical treatment of anode slimes is described by J. E. Hoffmann and K. E. Sutliff in their paper entitled Hydrometallurgical Processing of Kennecott Refinery Slimes, ibid. Electrolytic refinery slimes, i.e., anode slimes, usually contain between 10% and 40% elemental copper. Since copper can complicate ...

Lead leaching mechanism and kinetics in electrolytic ...

anode slime was reduced and obtained in a sulfuric acid mixture (Wei et al., 2017). The extent of manganese leaching in anode slime was> 99%. The content of lead, whose form was mainly lead sulfate, was larger than 43% after the anode slime was concentrated and leached. Shu et al. (2017) found that the main forms of manganese in anodeEFFECT OF OXIDIZING AGENTS IN EXTRACTING GOLD FROM ANODE SLIMEProcessing of copper anodic-slimes for extraction of valuable metals, Physicochemical Problems of Mineral Processing, 36, p. . Bard, Gabrielle and Sobral, 2008. Extraction of gold, silver and copper from the copper electrorefining anode slime; separation of the metals, Global Symposium on Recycling, Waste Treatment and Clean Technology.Chapter - L HYDROMETALLURGY & SOLUTION MININGRecovery of gold from copper anode slimes is a multi-stages process; at first stage selenium and copper were separated from anode slime. Then, anode slime was roasted Table 1. The chemical composition of anode slim Chemical composition Weight.% Au 0.106 SeO 2 16.1 CuO 5.90 Fe 2O 3 0.19 BaO 37.1 SO 3 22.1 PbO 2.80 Ag 2O 5.80 As 2O 3 0.88USA - Separative treatment of anode slime - Google ...A hydrometallurgical process is provided for the separative treatment of electrometallurgical anode slime containing precious metals and substantial amounts of tin dioxide and lead sulfate. The process is especially suited for treatment of anode slimes from the electrorefining of secondary copper to recover about 85% of the metal value contained therein, especially tin and precious metals.A Novel Process For Recovery Of Te And Se From Copper ...settle to the bottom of the electrolytic cells.
