A new approach is brought to diamond recovery from waste cutting segments. Unlike the commonly used hydrometallurgical processes, this approach offers the simultaneous recovery of copper with diamond. Besides, instead of strong acids, this work involves use of a dilute acid solution, reducing the evolution of toxic vapors. Copper base segments of waste diamond tools were used as anode, which were dissolved by applying potentials above the dissociation voltage of Cu. Simultaneously, the diamond grits detached from the segments and gathered at the bottom of the cell. Then, the dissolved Cu2+ cations were reduced, and Cu powders were electrodeposited at cathode without affecting the accumulated diamond particles. Eventually, the diamond particles could be collected from the bottom of the cell, providing the simultaneous recovery. In this work, the effect of individual process parameters on the outcome of presented approach is studied. The process parameters were then optimized, and mathematical models were developed for response variables by response surface methodology. Also, a mini-prototype was designed and operated at the optimized conditions to check the possibility of converging the proposed approach to industrial applications. Prototype tests show that all detached diamond could be recovered in 3 h and simultaneously with Cu powders.

A robust optimization model for sustainable and resilient closed-loop supply chain network design considering conditional value at risk Lotfi, Reza; Mehrjerdi, Yahia Zare; Pishvaee, Mir Saman; Sadeghieh, Ahmad; Weber, Gerhard Wilhelm (2021-06-01) One of the challenges facing supply chain designers is designing a sustainable and resilient supply chain network. The present study considers a closed-loop supply chain by taking into account sustainability, resilience, robustness, and risk aversion for the first time. The study suggests a two-stage mixed-integer linear programming model for the problem. Further, the robust counterpart model is used to handle uncertainties. Furthermore, conditional value at risk criterion in the model is considered in orde...
Advanced oxidation techniques for the removal of refractory organics from textile wastewaters Erol, Funda; Özbelge, Ayşe Tülay; Department of Chemical Engineering (2008) Ozonation is an efficient method to degrade refractory organics in textile wastewaters. In recent years, catalytic ozonation is applied to reduce ozone consumption and to increase “chemical oxygen demand” and “total organic carbon” (TOC) removal efficiencies. The ozonation of two industrial dyes, namely Acid Red-151 (AR-151) and Remazol Brilliant Blue R (RBBR) was examined separately both in a semi-batch reactor and also in a fluidized bed reactor (FBR) by conventional and catalytic ozonation with alumina a...
Design and characterization of TlInSe2 varactor devices QASRAWI, ATEF FAYEZ HASAN; Aljammal, Faten G.; Taleb, Nisreen M.; Hasanlı, Nızamı (Elsevier BV, 2011-07-15) TlInSe2 single crystal has been successfully prepared by the Bridgman crystal growth technique. The crystal, which exhibits compositional atomic percentages of 25.4%, 25.2% and 49.4% for TI, In and Se, respectively, is found to be of tetragonal structure with lattice parameters of a=0.8035 and c=0.6883 nm. The crystals were used to design radio frequency sensitive varactor device. The temperature dependence of the current-voltage characteristics of the device allowed the calculation of the room temperature ...
Development of a screening model for polymer flooding in multi-layer reservoirs ZarePakzad, Negar; Durgut, İsmail; Artun, Emre; Department of Petroleum and Natural Gas Engineering (2018) Polymer flooding is a chemical enhanced oil recovery method which aims to increase oil production from a water flooded oil reservoir by increase in water viscosity and reduction in water-oil mobility ratio. These changes result in significant increase in sweep efficiency of water comparing with water-only flooding technique. The objective of this study is to analyze the behavior of multilayer reservoirs under polymer flooding process, considering effects of reservoir characteristics, polymer properties and ...
A SIMPLIFIED APPROACH TO THE SETTLEMENT ESTIMATION OF PILED RAFTS Kalpakci, Volkan; Özkan, M. Yener (2012-01-01) In this study, a simplified approach to the settlement estimation of piled rafts resting on over-consolidated clay deposits is presented. For this purpose, a series of plane-strain and three-dimensional analyses were performed and their results are compared with the available data in the literature. It was found that the percentage decrease in the total settlements with the addition of piles with respect to the unpiled case is very closely estimated by both the plane-strain and the three-dimensional, simpli...
