Feb 03, 2021 0183 32 Possibilities for minimizing copper losses in converter slags include 1 settling the molten slag to recover entrained matte and copper, 2 smelting the slag with a suitable reductant to recover a copper-iron alloy or a low-grade matte 3 beneficiation of slags by magnetic separation, and 4 treatment of the slag by flotation...

Jan 13, 2021 0183 32 Slag formed in the smelting and converting reactions flows to the slag well Slag cleaning occurs as a result of contact with lower grade matte in passing through zone 1, by the roast reaction of copper sulfide and copper oxides by the reduction of copper oxide by sulfur and ferrous sulfide, and by the reduction of magnetite...

Jun 24, 2021 0183 32 The primary heat exchanger consists of a copper plate, which is cooled by water or thermal oil The heat is extracted via conduction underneath the slag The copper plate is mounted on a steel basin in which the thermal fluid water or oil captures the slag heat and cools the copper to prevent it from overheating and melting...

Technical description of slag drying 1 Scope of application HG direct heating rotary drum dryer is widely used in food, feed, chemical, pharmaceutical, mining, fertilizer and other industri According to the requirements of drying products, different heat sources can be used...

Abstract Copper slag is a by-product obtained during matte smelting and refining of copper This work reports an experimental procedure to investigate the effect of using CS as partial replacement of sand Six series of concrete mixtures were prepared with different proportions of CS ranging from 0 to 100 ....

Sep 01, 2011 0183 32 The recovery of heat from dry-granulated slag grains conventionally takes place in fluidized bed for improved heat transfer and also preventing agglomeration of the particl However, the disadvantage of fluid-bed is that slag is discharged at a temperature typically above 200 176 C, causing a considerable energy loss , Copper slag waste as a ....

Copper slag, an important by-product of the copper smelting process, is mainly composed of 2FeO SiO2, Fe3O4, and SiO2 Due to the sufficient metal oxides, copper slag is regard as a potential oxygen carrier OC , which can be applied in chemical looping technology This research proposed to use the granulated copper slag particles as precursor to produce oxygen carrier...

a difficulty with lowering the copper grade of slag, which necessitates the reprocessing of slag by slag , has improved a drying process of concentrates, the structure of furnace, the cooling system of furnace, , furnace created dust troubles in the waste heat boiler But the volume of copper matte increased due to the...

Dec 03, 2008 0183 32 I am sorry to inform you that for this application of drying Copper Slag where you are looking for Fluid Bed Dryers we from Buss-SMS-Canzler do not have such equipment in our fabrication program Best regards, Mr W Nussberger Buss-SMS-Canzler Branch Office Pratteln Hohenrainstrasse 10 CH-4133 Pratteln Tel 41/ 0 61-825 64 90...
