Hydrometallurgical leaching process has been identified as a viable procedure for recovering metals of value from their matrices. The optimization zinc recovery sphalerite in nitric acid solution was carried out this study. Central Composite Rotatable Design (CCRD) Response Surface Methodology (RSM) and Particle Swarm Optimization (PSO) tool matlab were deployed the studies. RSM modeling gave o...
