As a reusable secondary raw material resource, the steel mill dust contains a high amount of iron and zinc. Nowadays, most of the steel mill dusts are processed under the Waelz-Process. However, this process is limited or impossible without additional dust treatment and can only be operated economically with zinc contents over 20 wt%.
During the melting of steel scrap in an electric arc furnace (EAF), high amounts of dust—so-called steel mill dust or electric arc furnace dust (EAFDs)—are generated. These dusts contain a rich variety of different species, depending on the input material. Basically, the main components, among others, are zinc and iron.
The simple solution for steel mills was to dispose of the dust at a landfill site. Unfortunately, only a few landfills are able to take the EAF dust. Furthermore, compared to normal wastes, the disposal of EAF dust is more expensive. Tipping fees at landfill sites that accept the dust cost in the range of $150 to $200 per ton.
For steel to exist, it truly most go through the hottest fire. Steelmaking is the process of producing steel from iron ore. Iron and Steel Mill operations consist of Iron preparation, cokemaking, blast furnace work, and finishing operations. The World Steel Association's Overview of the Steelmaking process will help better visualize this ...
A new technology for the recycling of steel mill dust is the RecoDust process, which is the only process not needing any pretreatment steps. The large range of processable dusts, especially dusts ...
Protecting the Environment. Currently, US-based mini-mills using the Electric Arc Furnace (EAF) method to melt scrap steel generate more than a million tons of steel mill dust annually. Classified as a hazardous substance, most of this steel dust can be recycled to obtain zinc oxides used as a raw material for the world's zinc smelters.
Steel mill and foundry waste dusts containing zinc and/or lead oxides in addition to iron oxides are briquetted by means of a hydrocarbonaceous binder, together with sufficient carbon to reduce at least the lead and zinc oxides to the metal; the briquettes are preferably preferentially treated with an oxygencontaining gas at 350* to 600*F to selectively react with the binder to obtain strong ...
Cooling the Steel Mill with Dust Control. During the melting process of the steel-based demolition materials, the surrounding temperature can get unnecessarily hot.The furnaces used release copious amount of heat into the surrounding air, raising the temperature to undesirable heights.
The Bethlehem steel mill in Maryland was once the largest working mill in the world, employing 30,000 people at its peak in the 1950's. The collapse …

419 Mini Steel Mills dust arrestment equipment to achieve an Air Emissions emission level of less than 0.25 kg/t. Air emissions of particulate matter (PM) should be below 20 mg/Nm3 where toxic metals are present and 50 mg/Nm3 in other cases. This would correspond to a total dust emission of less than 1 kg/t of steel. SOx should be 2000
I come from a family of steel-making men, and I've seen what's about to happen in Bethlehem happen in other places in another time. The great …
990. Jun 15, 2010. #3. Always wear a respirator. Along with the steel dust are the fragments of grit that come off the belt that can get into your lungs and act like little tiny knives that cut up your lungs. Very, very bad.
About 99% of the total fumes and dust generated in steel-making process escape as fugitive emissions whereas slags also lead to release of fumes in the form of iron oxide, kish (graphite), soot and silica. ...

KWS designed heavy duty slide gates suitable for the demanding environment of a steel mill. The design incorporated mill duty cam follower bearings that could be greased externally. Pneumatic cylinders were designed with sufficient force to open and close under a head load of dense iron dust. Proximity switches were located on the gates so both ...
The main solid co-products produced during iron and crude steel production are slags (90% by mass), dust and sludge. On average, the production of one tonne of steel results in around 200 kg of co-products for the electric arc furnace (EAF) route and 400 kg for the blast furnace - …
Steel mill dust nowadays is a well-known secondary resource for zinc. Most of the companies treating this dust operate the established waelz process. However, even though it is known as best available technology, it finally only recovers zinc and does not create any value out of the other metals contained in the dust such as lead, iron etc.
The Waelz process is the oldest and most often applied technology for the recycling of dusty steel mill residues worldwide,especially for EAF dust.It is a pyro-metallurgical process characterized by the volatilization of non-ferrous metals like zinc,lead and cadmium out of an oxidised solid mixture by means of reduction by coke in a rotary kiln without generating a liquid slag.The recycling of ...
