Vitrification of copper flotation waste.
The vitrification of an hazardous iron-rich waste (W), arising from slag flotation of copper production, was studied. Two glasses, containing 30wt% W were melted for 30min at 1400 degrees C. The first batch, labeled WSZ, was obtained by mixing W, blast furnace slag (S) and zeolite tuff (Z), whereas the second, labeled WG, was prepared by mixing W, glass cullet (G), sand and limestone. The glass...
متن کاملEffect of grinding time on flotation recovery of copper smelting slags in Bardaskan district
Copper smelting slags are hard materials. Therefore,to recover their copper by flotation method, grinding should be carried out to obtain optimal particle size. Copper smelting slags in the Bardeskan district, with work index of 16.24 kwh/st, were grinded for 65 minutes to reach an acceptable degree of freedom for the flotation tests, with particle size of 80%, smaller than 70 μm. With this gri...
متن کاملMintek’s Advanced Optimisation Control Strategies in Milling, Flotation and Smelting
Mintek, specialists in mineral and metallurgical technology, have developed advanced optimisation control strategies in milling, flotation and smelting. The strategies address process specific problems namely downstream flow disturbances in flotation circuits from open milling circuits, fluctuating grade and recovery of flotation circuits and furnace fault conditions including power trips and e...

متن کاملDesigning of Synergistic Waste Mixtures for Multiphase Reactive Smelting
Electric arc furnace (EAF) dust, together with a mill scale and coke were smelted in a laboratory electric arc furnace. These metallurgical wastes consist of a many different phases and elements, making the reaction process complex. Thermo-chemical analysis of the reactions in metal, slag, and gas phases was done, and used for modeling of the mixture composition and energy consumption required ...
