· Electric arc furnace (EAF) dust is a waste generated in the EAF during the steel production process. Among different wastes, EAF dust represents one of the most hazardous, since it contains heavy metals such as Zn, Fe, Cr, Cd and Pb.

It was found that the incorporation of a fine particulate dust actually decreased the viscosity of the fluid. The present paper shows that selective extraction of zinc and lead can be achieved through judicious choice of the hydrogen-bond donor and it is also shown that metals in solution can be separated using cementation with zinc powder.

The characterization of Electric Arc Furnace (EAF) dust shows that bubble burst at the liquid steel surface is the principal source of dust emission. We have therefore developed an experimental device for studying this phenomenon. As in the case of the air–water system, the bubble-burst gives birth to two types of droplets: film drops and jet drops. The jet drop …

An electric arc furnace (EAF) is a furnace that heats material by means of an electric arc, combined with the action of chemical power provided by the use of oxygen and fuel. In electric arc furnaces, the charged material is directly exposed to an electric arc, and current from the furnace electrodes passes through the charged material.

 · Our models justify the importance of a r to the power -1 density law in the winds for efficient formation and survival of dust grains. The dust production rate scales linearly with the mass of the central BH and varies as a power law of index between 2 to 2.5 with the dimensionless mass accretion rate.
