At present, copper smelting slag is not effectively recycled and wasted. Copper contains FexO at more than 40 mass%. For the utilization of as a Fe resource, it necessary to separate Cu in slag. recycling from slag, FeS-based matte can be introduced use sulfurization concentrate into sulfide finally recover copper. In previous paper, kinetic model was developed simulate coupled reactions betwee...

During the pyrometallurgical extraction of copper, a significant fraction this metal is lost with discard slag, which decreases profits and overall copper recovery. These losses can be reduced by using settling furnace, in suspended droplets containing separate from slag under influence gravity. An industrial trial was conducted furnace to increase knowledge effect temperature time on content t...

With the increases in costs of iron and copper ores, incongruity between significant imports these ores into China ongoing accumulation unused slag has greatly increased. Even so, there are few low-value methods for utilization slag. The present work demonstrates processing this material via reduction whilst smelting wear-resistant cast iron. This system is able to recover copper, iron, zinc, l...

To determine slag properties and the factors influencing these for optimization of operating conditions in copper flash smelting process, composition microstructures quenched converting slags have been analyzed. Thermodynamic software FactSage 8.2 has used to investigate effects matte grade, SO2 partial pressure, Fe/SiO2 ratio on liquidus temperature content slag. The possibility recover valuab...

543 Introduction During the last years, due to world-wide economic recession and a large inventory of stock, copper reached a historical value of 0.59 US$/pound in 2001. This fact meant closing down many important mining companies in the world, mainly in USA. On the other hand, strong environmental restrictions have been imposed on the mining activity, and it is expected they will become more r...

bardsir region is one of the richest regions of metallic deposits, especially copper, in the east of iranian plateau. most of the metallic deposits in bardsir region are located on the western and southwestern parts, in k?h panj area. some of the mines have been exploited since prehistoric times through historic to islamic periods. the data presented here are collected during the second season ...

The leaching characteristics of slag and fly ash from copper-cobalt smelting in the Zambian Copperbelt were studied using pH-static leaching experiments (CEN/TS 14997). The release of metallic contaminants as a function of pH and the influence of fine dust particles and/or time on leaching were investigated. Three types of slag samples with decreasing portion of particles < 500 μm were prepared...
