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...
متن کاملZinc Stripping from Steelwork Dust
Recycling is extremely important for steelmaking. In developed countries, about 60% of steel is manufactured from scrap. The scrap contains 0.5% of zinc in average, and this percentage steadily increases. During the steelmaking process both in basic oxygen furnaces (BOF) and in electric arc furnaces (EAF), all volatile zinc is released and forms airborne particles of dust. About 20 kg of dust i...
متن کاملOptions of Utilising Steelmaking Dust in a Non-metallurgical Industry
Recycling of by-products of the steelmaking process in electric arc (EAF) furnaces is an important activity from the perspective of environmental protection as well as the steelmaking industry itself. This article is a discussion concerning the selected research results in terms of utilisation of steelmaking dusts containing 4 12 % of zinc in manufacture of cement bricks, ceramic construction m...
