Lead Sintering Gases The strong SO2 gases discharged from lead sintering ma-chines are generally used for producing sulfuric acid. The weak discharge gases normally are passed through baghouses before being discharged to the atmosphere. Again the FGD system would be installed between the baghouse and the stack. Moly Plant Tail Gases
Multi-source ferrous metallurgical dust and sludge are significant components of iron-containing solid waste in the iron and steel industry. It is crucial for the sustainable operation of steel enterprises to recycle iron from ferrous metallurgical dust and sludge (FMDS) for use in steel smelting. However, besides Fe, FMDS also contains valuable elements such as Zn, Pb, …

The processing of lead concentrate into metallurgical lead involves three major steps: sintering, reduction, and refining. A diagram of a typical facility, with particle and gaseous
The sludge from the water supply plant,named the water supply sludge,contained 60%~80% of water,is becoming a urgent task in controlling the pollution of the urban solid waste .Based on the research objective,the experiment of the sintering bricks is carried out with this sludge and fly ash and a little clay.The results show that the sintering products,sintered with 30%~45% …
Damage of the sludge. The steel making process makes a lot of sludge (about 8 to 12% of the steel production), such the blast furnace sludge, gas sludge, steel rolling sludge, steel rolling iron oxide scale, sintering dust, steel pipe graphite sludge, etc. Get rid of these sludge will help the plant to reduce the cost for the product and prevent pollution.
Lead and Zinc Sintering | IntechOpen. 06-02-2013· 1.2. Why sintering. Lead and zin metals are produced in blast furnace. In a blast furnace, ore, coke and flux are continuously supplied through the top of the furnace, while air (sometimes with oxygen enrichment) is blown into the lower section of the furnace, so that the chemical reactions take place throughout the furnace as the …
Herein, a co-sintering strategy of MSWI FA and LS had been proposed, it introduced CaF 2 into the system and a series of assessments were carried out to investigate the influence of sintering temperature, heavy metal volatilization, as well as the compressive strength of the value-added product. It was expected that the CaF 2 would significantly lower the …
Sewage sludge can be utilized as an alternative raw material for manufacturing sintering brick to achieve energy recovery and resources recycle, which, thus, may have the potential to reduce GHG emissions associated with sludge treatment. However, the carbon footprint of the sludge-based sintering brick manufacturing route remains unclear, and the …
The sludge-based forming thermal reduction can be used to improve the resource utilization ability of sintering dust. This paper discussed the feasibility and mechanism of sewage sludge as a binder and reducing agent to facilitate iron recycling from sintering dust by mixing wet sludge to form and adding dry sludge to reduce.
The leachate sludge (LS) and fly ash (FA) are the foci of hazardous wastes which generated from the municipal solid waste incineration (MSWI). The current work developed a new way to use energy from MSWI process for the on-site sintering of LS and FA at a relatively low temperature.
An innoxious sinter process for treating the mud from sewage treatment plant includes such steps as proportioning raw materials including said mud as main material to ensure enough Si content, dewatering, drying, granulating by 15-20 mm, and sintering at 1100-1250 deg.C for 10-15 min to obtain haydites.
