An optimization study on the leaching of zinc cathode melting furnace slag in ammonium chloride by Taguchi design and synthesis of ZnO nanorods via precipitation methods

Withdrawn: Chemical co-precipitation synthesis of spinel manganese ferrite nanoparticles (MnFe2O4): Morphological characterizations and magnetic properties

“…Specific surface areas of the manganese ferrite nanopowders were measured by BET method. Moreover, average particle size of the products was calculated by following equation [19]:…”

An Influence of EAF Dust Calcining Conditions on Zinc Leaching Efficiency in Ammonium-Chloride Media

“…According to the literature data, there are several hydrometallurgical methods for dusts processing [6][7][8][9][10][11][12], however, ammonia-chloride leaching is considered to be the most selective for zinc extraction in relation to impurities ratio [13][14][15][16][17][18]. Preliminary tests of ammonia-chloride leaching confirmed that a significant part of zinc is in the form of a stable compound (ZnFe2O4), which is insoluble in ammonium-chloride medium [10][11][19][20][21]. Figure 2 shows the mineralogical composition of the solid residue after ammoniumchloride leaching.…”

Optimization of Nickel Extraction From Lateritic Ore in Hydrochloric Acid Solution With Hydrogen Peroxide by Taguchi Method

“…Therefore, optimization of leaching parameters is very important. Taguchi method is widely used in optimization studies, both leaching studies and other scientific fields (Bese et al, 2010;Abali et al, 2006;Demir and Donmez, 2008;Babaei-Dehkordi et al, 2013;Asl et al, 2015;Dogan and Yartasi, 2014;Copur, 2002;Abali et al, 2011;Moghaddam et al, 2006;Ata et al, 2001;Safarzadeh et al, 2008;Ilyas et al, 2010;Zolfaghari et al, 2011). One of the advantages of Taguchi method is to keep costs to a minimum level compared to conventional experimental design methods and closer performance to the desired level.…”
