Redox potential (Eh) control plays a significant role during sulfide mineral flotation by influencing the reactions on surface of minerals and accordingly behaviour. In this study, metallurgical performance typical copper minerals, molybdenite as well gangue (e.g., pyrite, tennantite, enargite) under different pH Eh conditions cell were investigated. The molybdenum processing plant at Sungun co...

In this study, a plant-based adsorbent was used in order to remove lead, nickel, cobalt and cadmium metals from wastewater sample collected Sungun mine real wastewater. The biosorbent one of the most abundant native plants region, named Chrysopogon zizanioides (C. zizanioides). root powder C. heavy sample. characterized by FTIR, SEM, HR-TEM, EDS, BET ZPC analyses. effect pH, initial concentrati...

The life cycle cost of a system is influenced by its maintainability. Maintainability is a design parameter, whose operational conditions can affect it significantly. Hence, the effects of these operational conditions should be quantified early in the design phase. The proportional repair model (PRM), which is developed based on the proportional hazard model (PHM), can be used to analyze mainta...

All steps of a mining project generally disturb the environment'soriginal condition during construction. Therefore, it is crucial toimplement an appropriate mine reclamation plan throughout all mineplanning stages from sustainable and environmental point of view.Planting the suitable plant species in each step of any reclamationplan and each area is one of the necessities in this respect.Select...

Abstract Backbreak (BB) is one of the serious adverse blasting consequences in open-pit mines, because it frequently reduces economic benefits and seriously affects safety mines. Therefore, rapid accurate prediction BB great significance to mine design other production activities. For this purpose, six different swarm intelligence optimization (SIO) algorithms were proposed optimize extreme lea...

post-mineralization activities may cause difficulties in the process of ore modeling in porphyry deposits. sungun, nw iran, is one of the porphyry copper deposits, in which dyke intrusions have made ore modeling more complicated than expected. among different kinds of dykes, two types were chosen and the consequent geostatistical analyses were applied on. in this study, simple directional vario...

The appropriate operating of mining machines is affected by both the executive and environmental factors. Considering the effects and the related risks lead to a better understanding of the failures of such machines. This leads to a proper prediction of the reliability parameters of such machines. In this research work, the reliability and maintainability analysis of the loading and haulage mac...

The flotation circuit in Sungun copper plant consists of two column flotation cells as cleaner, having fixed-spargers system. To achieve the expected aims in flotation step, there are serious operational challenges such as: fast choking of the static mixers, boiling problem, burping phenomena and pulp overflow to concentrate lander, maintenance and control problems. An attempt was exerted by im...
