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...

متن کاملExtraction of Tin and Copper by Acid Leaching of PCBs
Printed circuit board (PCB) waste is generally dumped as a landfilling or treated pyrometallurg ically, which consumes enormous power, generates hazardous gases and also destroys valuable PCB components. For recycling of the components, they must be separated from the printed circuit boards which is a cumbersome task. For its simplification, the rate of d issolution of solder with acids like Hy...

Oil is obtained from rice bran, by the process of extraction with petroleum solvents, whereas the edible grade oil is the one refined by neutralisation with alkali.
متن کاملDemonstration Plant Equipment Design and Scale-Up from Pilot Plant of a Leaching and Solvent Extraction Process
Germanium recovery from coal fly ash by hydrometallurgical procedures was studied at the pilot scale (5 kg of fly ash/h). Results were used to design the equipment of a demonstration-sized plant (200 kg of fly ash/h). The process is based on hydrometallurgical operations: firstly a germanium extraction from fly ash by leaching and a consequent Ge separation from the other elements present in th...
