This technological procedure is divided into two phases, first slow cooling of slag on the air for 24 hours, and then accelerated cooling with water for 48 hours. Within the research following methods were used: calculation of nonstationary slag cooling, verification of the calculation using computer simulation of slag cooling in the software package COMSOL Multiphysics and experimental verification of simulation results. After testing of the experimentally gained samples of slowly cooled slag it was found that this technological procedure gives the best results in promoting growth or coagulation of dispersed particles of copper sulfide and copper in the slag, thereby increasing the utilization of the flotation process with a decrease of copper losses through very fine particles.}, number={2}, journal={Metallurgical and Materials Engineering}, author={Mihajlović, Aleksandar and Kamberović, Željko and Korać, Marija and Gavrilovski, Milorad and Jovanović, Nikola}, year={2015}, month={Jun.}, pages={127–141} }
