“…However, when the relevant solid phases, such as Pb(OH)Cl, were detected in industrial wastes, they were characterized as easily leachable in certain solvents [6]. Moreover, as presented in Table 1, the solubility of lead compounds in HNO 3 solution (3.3 M and with L/S = 10) is almost quantitative.…”

“…The extraction of lead from the respective ores or minerals by leaching was examined during several studies [1][2][3], although nowadays most research efforts are focused on the possibility of recovering lead from industrial wastes, such as its recycling from used batteries [4,5]. Among others, lead was also extracted and recovered from electric arc furnace dusts [6], from alloy wire * Corresponding author.…”

“…The two basic methods of recovery of zinc include: hydrometallurgical and pyrometallurgical method (Havlik et al, 2006;Jha et al, 2001;Leclerc et al, 2002;Leclerc et al, 2003;Shawabkeh et al, 2010;Youcai et al, 2000). Hydrometallurgical methods are based on leaching solutions of zinc waste using sulphuric acid or hydrochloric acid.…”

Dust generated at an electric arc furnace during steel production industry is still not a solved problem. Electric arc furnace dust (EAF) is a hazardous solid waste. Sintering of well-prepared briquetted mixtures in a shaft furnace is one of possible methods of EAFD utilisation. Simultaneously some metal oxides from exhaust gases can be separated. In this way, various metals are obtained, particularly zinc is recovered. As a result, zinc-free briquettes are received with high iron content which can be used in the steelmaking process. The purpose of the research was selecting the appropriate chemical composition of briquettes of the required strength and coke content necessary for the reduction of zinc oxide in a shaft furnace. Based on the results of the research the composition of the briquettes was selected. The best binder hydrated lime and sugar molasses and the range of proper moisture of mixture to receive briquettes of high mechanical strength were also chosen and tested. Additionally, in order to determine the thermal stability for the selected mixtures for briquetting thermal analysis was performed. A technological line of briquetting was developed to apply in a steelworks.

“…[10][11][12][13][14][15][16][17][18] In addition, several other hydrometallurgical processes were developed, including the use of ammoniac solutions and chloride leaching. 1,[19][20][21][22][23] A high zinc-leaching rate was achieved during these processes. However, severe leaching conditions, such as a high temperature (90-95°C) and high acidity (200-250 g/L), were required for the decomposition of zinc ferrite.…”

An integrated process for the recovery of zinc that is generated from zinc hydrometallurgy in residues was developed. A mixture of residue and ferric sulfate was first roasted to transform the various forms of zinc in the residue, such as ferrite, oxide, sulfide, and silicate, into zinc sulfate. Next, water leaching was conducted to extract the zinc while the iron remained in the residue as ferric oxide. The effects of the roasting and leaching parameters on zinc recovery were investigated. A maximum zinc recovery rate of 90.9% was achieved for a mixture with a ferric sulfate/residue weight ratio of 0.05 when roasting at 640°C for 30 min before leaching with water at room temperature for 20 min using a liquid/solid ratio of 10. Only 0.13% of the iron was dissolved in the water. Thus, the leaching liquor could be directly returned for zinc smelting.
