“…Other pyrometallurgical processes used for processing metallurgical zinc coinveing dust are: technology Contop [13] or ENVIROPLAS process [14]. A number of hydrometallurgical processes have been develop in order to treat these dusts from steel plant for recovering zinc from ferrite -phases such as acidic or caustic leaching, microwave assisted extractions [15]. EAFD leaching process generally includes two steps: [13] • leaching of zinc into solution, which most often uses sulfuric acid;…”

Zinc ferrite ZnFe2O4 both in the micro and nano scale is widely used in various fields. The article discusses the structure of this compound and its properties in the nanoscale, which is clearly different from those which the ferrite shows in the microscale. The properties of dust generated electric arc furnace, which can contain up to 40% zinc, substantially in the form of ZnFe2O4 are disscused here. Specific properties (electric, magnetic, thermal) of zinc ferrite nanoparticles determine the very wide possibilities of their use, inter alia as catalysts, absorbents, gas sensors, and a tool to combat cancer.

“…The conventional processes of recovering zinc from galvanizing dross include pyrometallurgical and hydrometallurgical processes. In general, the pyrometallurgical routes are high energyconsuming and require large capital investments; 4,5) while the hydrometallurgical processes are usually quite complex and consume a great deal of lixiviating reagent. 6) So far, super-gravity separation has been successfully applied in removing impurities from alloy melt 7,8) and recovering valuable elements from different kinds of slag.…”

The removal of iron-containing dross particles and recovery of zinc from galvanizing dross by super-gravity separation was investigated using a model Zn-Fe-Al alloy. After super-gravity separation, the high purity molten zinc went through the filter, while the residue mainly consisting of dross particles was intercepted by the filter and separated from the molten zinc. The effects of gravity coefficient and separating temperature on zinc recovery and iron removal were investigated. The preliminary results show the supergravity separation is a promising method of recovering zinc from galvanizing dross.
