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...

Altınsel, Yiğit; Sarılar, Sena; Yılmaz, Orhan; Atalay, Mustafa Ümit; Altun, Naci Emre (null; 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...
Bottle Roll Testing for Cyanidation of Gold Ores: Problems related to Standardized Procedures on Difficult-to-Process Ores
Çetin, Mahir Can; Altun, Naci Emre; Atalay Mustafa Ümit; Büyüktanır Aktar, Karden (2017-06-11)
This paper evaluates the influence of some of the critical parameters of bottle roll testing procedure on gold extraction results and leaching behaviour. The conventional testing procedure with special em...
Extraction of zinc from smithsonite by ammonia leaching
TALAN, DENİZ; ATALAY, MUSTAFA ÜMİT; Altun, Naci Emre (2017-06-11)
– In this study, an ore taken from Kayseri region of Turkey was used. Characterization studies showed that the run-of mine ore is rich in oxide minerals, cerussite (PbCO3) and smithsonite (ZnCO3). The aim of the study was ...
Loading Behaviours of Nickel, Cobalt and Scandium on Different Types of Resin
Altınsel, Yiğit; Altun, Naci Emre; Topkaya, Yavuz; Atalay, Mustafa Ümit; Kaya, Şerif (2017-06-01)
Importance of laterite nickel ores are increasing day by day because of their nickel, cobalt and scandium contents. Processing operations of laterite ores generally consist of scrubbing, high pr...
