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...
Effects of abandoned coal mine on the water quality
Tozsin, Gülşen; Arol, Ali İhsan; Duzgun, Sebnem; Soydan, Hilal; Torun, Abdulvahit (2022-02-01)
Improving effective strategies to control acid mine drainage (AMD) in abandoned mine areas is a significant challenge because of water quality issues. AMD is a serious water pollution problem. The water in the area where t...
Preliminary assessment of spray coating, solution-immersion and dip coating to render minerals superhydrophobic
Camalan, Mahmut; Arol, Ali İhsan (2022-01-01)
Achieving hydrophobic surfaces on mineral particles is an active research topic in mineral processing. The conventional technique for achieving good hydrophobicity is to mix mineral particles in solutions of organic salts ...
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...
