The present work focuses on investigation of the effective recovery of heavy metals from molten fly ash by applying chloride-induced volatilization. In particular, the effect of unburned carbon on the chloride-induced volatilization of lead, zinc, and copper from model and real molten fly ashes was investigated in the temperature range 873–1173 K under a N2 atmosphere. As a result, …

This study demonstrated that WAS removed 97% of zinc and 86% of lead within the first minute of contact with the mine water (0.5 g of WAS per 20 mL of mine water), with a maximum measured removal ...
Zinc recovery from MSWI fly ash using acidic leaching and chemical precipitation was studied at pilot scale. The leached fly ash was re-incinerated in order to destroy toxic dioxins. 75-150 kg/h ...
The production of EAFD chiefly results from the following three reasons [2, [10], [11], [12]]: (1) Volatilization of metals with low boiling point,such as lead and zinc, (2) Iron and slag phases triggered by CO bubble bursting at the slag-gas interface, (3) Low-density additives (e.g.carbon or limestone) taken away with the flue gas at high processing temperature …
Clean and efficient recovery of lead from zinc direct leaching residue has good environmental and economic benefits. The paper firstly developed a clean and efficient …
Hot-dip galvanizing is known for more than 250 years. It is a common and reliable method used for the formation of anticorrosive zinc coatings on iron and steel workpieces of different shapes and dimensions ranging from tower constructions, masts, bridge parts, pipes, sheets, strips to buckets, hinges, hasps, nails (Mass and Peissker 2011).The coatings have …

Zinc ash has different properties depending on how it is processed and the quality of the zinc used. Generally, zinc ash contains a number of chemical components, including zinc oxide, zinc ferrite, and small amounts of other metals. Type of Zinc Ash. Zinc ash usually comes in the form of a fine powder with a gray or white color. Powder ...
Three kinds of fly ash from continuous stoker-type MSWIs and a kind of fly ash from an ash melting plant (AMP) were investigated. XAFS measurements were carried out on beam line BL01B1 at SPring-8. The lead, zinc and antimony spectra were collected in fluorescence detection mode at room temperature with a Si (111) or Si (311) monochromator.
Typically, the zinc ash represents 12–20% of total zinc consumed during hot dip galvanizing (Ainsley, 2019; Barakat, 2003). It gives even several dozen tons of the waste accumulated monthly in a galvanizing plant (Barakat, 2003). The zinc ash is formed on the bath surface as a result of molten zinc oxidation in a contact with air.
