“…In a research work conducted by Ranjbar et al (2014) [73], the recovery of gold from copper anode slime by means of a novel process utilizing magnetite nanoparticles (MNPs) was studied. All the gold content of copper anode slime was dissolved in thiourea solution as leachant and a positive complex of gold and thiourea was obtained as a result.…”

Precious metals which include the platinum group, gold, and silver, play indispensable roles in high technology industries of the modern world due to their outstanding physical and chemical properties. As a result of diminishing availability of mineral sources, increasing demand, and environmental concerns, the recovery of precious metals from both leaching and industrial waste solutions is becoming a very important technology. Magnetic solid phase extraction (MSPE) is a technique that has received substantial consideration in the separation and recovery of precious metals because of the many advantages it offers compared to conventional methods. This technique is based on the extraction of different analytes from solutions using solid adsorbents with magnetic properties. This review focuses on different types of magnetic adsorbents, the main procedures used for synthesis, characterization and their application in precious metals recovery based on recently published literatures.

“…Nevertheless, the separation and recovery of gold is not actually simple, which is due to the low concentration of gold in environmental, geological and metallurgical materials and insufficient sensitivity [3]. Various technologies that have been employed for the recovery and enrich gold include co-precipitation [4], ion exchange [5][6], solvent extraction [7] and adsorption [3,[8][9].…”

“…In the recent years, magnetic materials have been widely used as an adsorbent for treatment of toxic contaminates [7][8][9]. Moreover, magnetite metal oxides or various ferrites are frequently used in hydrometallurgical extraction process for recovery of precious metals [10] and heavy metals [11,12], and regulating digestion of high silica bauxite [13]. Among the available magnetic sorbents, inorganic spinel ferrites and their composite materials were widely used in water treatment due to its unique advantages of magnetic and chemical stability [8,[14][15][16].…”

Abstract-In order to develop water treatment performance, graphene oxide based inverse spinel nickel ferrites (GONF) and reduced graphene oxide based inverse spinel nickel ferrites (rGONF) nanocomposites were prepared using graphene oxide (GO) and inverse spinel nickel ferrite (NiFe 2 O 4 ) by thermal precipitation method. The interface interactions of GO and NiFe 2 O 4 were studied. The X-ray diffraction spectrometer (XRD), and Fourier-transform infrared spectroscopy (FT-IR) and BET studies showed that the formation GONF and rGONF. Scanning electron microscopy (SEM) studies observed porous surface morphology of GONF and rGONF. The magnetic studies revealed that the ferromagnetic property of GONF and rGONF, but the later one shows less Ferro magnetic intensity than GONF. It was well performed for the adsorption removal As(V) and subsequently easy magnetic separation from water. The sorption studies revealed that the sorption was rate-limiting pseudo -second-order kinetics with mono layer chimisorptions on homogeneous surface of GONF and rGONF. The sorption capacity of GONF enhanced by the reducing of GO. The sorption capacity of rGONF (106.38 mg/g) was higher than GONF (81.30) for As(V). It was decreased with increasing temperature from 293 to 323 ± 2 K. The influence of sorption with solution pH and spectral characterisation of loaded GONF-As(V) or rGONF-As(V) were further confirmed that the sorption occurred through an inner sphere surface complexation by chemical interactions.
