recovery of nickel from spent catalysts by hydrometallurgical method
there are no appreciable amounts of nickel resources in iran; therefore, secondary resources of this element are to be more considered in future. spent nickel catalysts that are used in various industrial processes are one of them. for example nickel catalyst that is used in hydrogenation of edible oil have large amounts of nickel and they are generally supported on porous materials like silica...
متن کاملHydrometallurgical Recovery of Metals from Large Printed Circuit Board Pieces
The recovery of precious metals from waste printed circuit boards (PCBs) is an effective recycling process. This paper presents a promising hydrometallurgical process to recover precious metals from waste PCBs. To simplify the metal leaching process, large pieces of PCBs were used instead of a pulverized sample. The chemical coating present on the PCBs was removed by sodium hydroxide (NaOH) tre...
متن کاملHydrometallurgical Recovery of Nano-Palladium from Spent Catalyst
Hydrometallurgical recovery of nano-palladium (Pd) from spent Pd/Al2O3 catalyst has been investigated. The Pd content in the spent catalyst sample was assayed to be 0.42% while the remainder was mainly aluminum oxide. Mixture of HCl and AlCl3 was studied as leaching agent for the sample. The Pd was deposited with formic acid. Different parameters affecting leaching and deposition processes such...

CORE FLOOD STUDIES TO EVALUATE EFFICIENCY OF OIL RECOVERY BY LOW SALINITY WATER FLOODING AS A SECONDARY RECOVERY PROCESS
Various researches on laboratory and field scale illustrate that manipulating the ionic composition and the ion concentration of injected water can affect the efficiency of water flooding and the interaction of injected water with rock and other fluids present in porous media. The objectives of this paper are to investigate parameters that affect low salinity water flooding; mainly the effect o...
