Pressure leaching of copper sulphide from nickel refining: Initial experiments for valorisation

Removal of Cadmium, Zinc, Lead and Copper by Sorption on Leaching Residue from Nickel Production

Odstránenie Cd, Zn, Pb a Cu sorpciou na vylúhovanom zvyšku z produkcie Ni A leaching resudue from the nickel production (LRNi), was used to study the removal of selected bivalent cations (Cd, Pb, Cu and Zn) from model aqueous solutions. Batch-type experiments have been performed in solutions with initial concentrations of heavy metals in the range of 20-400 mg.L and the adsorbent dosage 2 g.L. ...

copper and nickel recovery from electroplating sludge by the process of acid-leaching and electro-depositing

in this work, we developed a method which combined the processes of acid-leaching, ammonium jarosite precipitating and electro-depositing to recover copper and nickel from electroplating sludge. residual sludge from an electroplating plant located in qingdao was used for acid-leaching, and more than 95% of copper, nickel, zinc, chromium and iron were extracted from the sludge. after acid-leachi...

Comparison of various extractants for recovery of Copper from Sarcheshmeh Chalcopyrite concentrate Ammonia/Ammonium Carbonate Leaching

Solvent extraction of copper from the copper leach solution obtained from the ammoniacal carbonate leaching of the Sarcheshmeh copper concentrate was carried out, and the performance of CP-150, LIX984N, and Kelex100 as well as the effects of different parameters involved were investigated. According to the results obtained, the extraction kinetics of all the three extractants was fast. High con...

The influence of sulphide transport on the growth and properties of copper sulphide films on copper

Optimized Leaching Conditions for Selenium from Sar-Cheshmeh Copper Anode Slimes

The recovery process of selenium from Iranian Sar-Cheshmeh copper anode slimes employing hydrometallurgical methods has been investigated. The copper anode slimes are made up of those components of  the anodes, which are not soluble in the electrolyte. They contain varying quantities of precious metals like gold, silver, selenium and tellurium. They are being extracted as a by product in th...
