Investigation on Gold Dissolution Performance and Mechanism in Imidazolium Cyanate Ionic Liquids Zhang, Na; Zhang, Yuxin; Liu, Zhengyu; Liu, Ziyuan; Sun, Chunbao; Altun, Naci Emre; Kou, Jue (2024-02-18) To explore green gold leaching reagents, a series of imidazolium cyanate ionic liquids (ILs), 1-ethyl-3-methyl-imidazolium cyanate ([C2MIM][OCN]), 1-propyl-3-methyl-imidazolium cyanate ([C3MIM][OCN]) and 1-butyl-3-methyl-i...
Optimizing rare earth element beneficiation using response surface methodology and Knelson concentrator Li, Lixia; Zhou, Mingliang; Liu, Feifei; Liu, Zhe; Altun, Naci Emre; Yuan, Zhitao; Liu, Jiongtian (2024-01-01) The beneficiation of rare earth elements is a crucial process in unlocking the potential of these valuable resources. This study investigates the utilization of response surface methodology in optimizing rare earth benefic...
Gravity-based pre-concentration strategies for complex rare earth ore containing niobium and zirconium Zhou, Mingliang; Li, Lixia; Liu, Feifei; Liu, Zhichao; Altun, Naci Emre; Yuan, Zhitao; Liu, Jiongtian (2024-01-01) The Balzhe rare earth mine, renowned for its rich reservoirs of niobium, zirconium, and rare earth elements, poses a unique challenge due to its diverse and interbedded mineral composition. Despite the abundance of these e...
Molecular dynamics simulations of the solubility and conformation change of chitosan grafted polyacrylamide: Impact of grafting rate Zhao, Wei; Zou, Wenjie; Liu, Fengyang; Zhou, Fang; Altun, Naci Emre (2024-01-01) Graft modification is an effective approach to improve the water solubility and molecular weight of chitosan. This work investigated the effect of grafting rate on water solubility of chitosan-grafted polyacrylamide (Chi-g...
Modelling of continuous centrifugal gravity concentrators using a hybrid optimization approach based on gold metallurgical data Sakuhuni, Givemore; Altun, Naci Emre; Klein, Bern (2022-03-30) Conventional optimization procedures for Continuous Centrifugal Gravity Concentrators (CCGCs) impose a priori weighting on objectives and results in a single optimum point, thereby failing to exploit the competing grade/re...
Comparison of flash flotation and gravity separation performance in a greenfield gold project Erkan, Emre; EKMEKÇİ, ZAFİR; Altun, Naci Emre (2022-01-01) Recovery of gold and gold-containing sulfide mineral particles requires multiple-stage recovery processes starting from the grinding circuits to avoid over-grinding of the liberated gold particles. Due to high density, the...
