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...
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...
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...
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...

Altınsel, Yiğit; Sarılar, Sena; Altun, Naci Emre; Topkaya, Yavuz; Yılmaz, Orhan (2020-10-10)
Marble Wastes as a Calcareous Sorbent for SO2 Control in Thermal Power Plants
Altun, Naci Emre (2019-08-20)
In this study, the possibility of using marble wastes for SO2 control in coal-fired thermal power plants was assessed. The goal is suggesting marble wastes as an altarnative calcareous sorbent to limestones for use in WFGD...
Flotation of Pyrite from Flotation Tailings
Altınsel, Yiğit; Sarılar, Sena; Yılmaz, Orhan; Atalay, Mustafa Ümit; Altun, Naci Emre (null; 2018-10-26)
Centrifugal Gravity Concentration as a Novel Way for Extending Limits of Conventional Process Circuits
Altun, Naci Emre (2018-10-26)
Use of Ultrasound to Enhance Flotation Performance: Flotation Cleaning of Oil Shale after Ultrasonic Pre-Treatment
Altun, Naci Emre; Hiçyılmaz, Cahit (2018-08-20)
This study aims at determining the contribution of ultrasonication to conventional flotation. In this regard, enhancing the performance of flotation cleaning of an oil shale sample was attempted using ultrasonic pre-treatm...
