Micro-organisms and sinter. When hot springs overflow they often form layers of sinter – a rock made of very fine-grained silica – that takes the form of flats, terraces and mounds. Sinter terraces are one of the most distinctive features of geothermal areas, and provide evidence for past geothermal activity.
Introduction. The stack emissions of the iron ore sinter plant contain flue gas with CO, CO 2, H 2 O vapors; fine particles of iron ore, sinter components; and particulates of SO x, NO x, KCl, and PCDD/Fs.The appearance of the stack emissions varies with the plume contract, its contents, and the meteorological conditions, …

The changing coke consumption declines the total chlorine input amount only by 1%. It has a minor influence on the chlorine balance. About 15% of total chlorine feedstock is leaving the sinter plant via the solid sinter. The other 85% of the chlorine input leaves the sinter plant by stack-gas.

Steel making using the integrated blast furnace (BF) process route is still the dominant steel production method covering 70% of worldwide steel production and iron ore sintering is one of the most important iron sources within this process, which represent 70–80% of charged iron-bearing materials into modern BF [].Inside this route, sinter …
Lead sinter plant trials have been carried out at the Xstrata Zinc sinter plant (Mount Isa) by the author and Xstrata Zinc staff. The design of the hood at the Mount Isa sinter plant is such that there is a 10 cm gap between the ventilation hoods for the main feed hopper and the sinter machine. This space is sufficient for thermocouples to be ...
sinter plants are designed to meet the most stringent environmental regulations.

We provide processes for limiting dioxin, SOx, and NOx emissions, while incorporating noise attenuation ...
The sinter plant is a major contributor to dust emissions from integrated iron and steel works. The dust emissions from sinter plants are generated from raw material handling, wind box exhausts, and the discharge end of the sinter strand associated with sinter crushers, and hot screens, the cooler, and cold screens. ...
Sinter plant: Freshwater is essential for serving as a coolant in the sinter machines, ignition hood, and fan within the sinter plant. The intake demand consists of 350 m 3 /h of raw water and 150 m 3 /h of make-up water. In a sinter plant, water serves multiple functions, primarily encompassing the cooling of the sinter machines, the …
In the sinter plant, raw material such as ore fines, coke or coal, dust from the furnace off-gas system, and binding material are discharged from feed bins in the correct proportions through weigh feeders and conveyed to a blending system. The raw materials are blended in a rotating mixing drum. ... P. Rodda, in Encyclopedia of Geology, 2005.

14th International Symposium on Process Systems Engineering. Haoran Li, Tong Qiu, in Computer Aided Chemical Engineering, 2022. 2.1 Process description. The sintering process is an important thermochemical process in the blast furnace ironmaking system. It involves the heating of fine iron ore with flux and coke fines or coal to produce a semi …
12.5.2.1 Sinter - Emissions from sinter plants are generated from raw material handling, windbox exhaust, discharge end (associated sinter crushers and hot screens), cooler, and cold screen. The windbox exhaust is the primary source of particulate emissions, mainly iron oxides, sulfur oxides, carbonaceous
The remaining 2% of domestic iron ore was produced for non-steel end uses. Seven open-pit iron ore mines (each with associated concentration and pelletizing plants), and three iron metallic plants—one direct-reduced iron (DRI) plant and two hot-briquetted iron (HBI) plants— operated during the year to supply steelmaking raw materials.
Modern sintering process consists of three stages: sintering raw material preparation, sintering, and sinter processing (Fig. 1).Sintering raw material preparation stage consists of the steps such as uniform mixing of raw material in storage, and processing, batching, mixing, granulation, and distribution of flux and fuel.
A typical sinter plant consists of a number of sequential operating units with the sinter machine at the heart of the plant. The simplified process sequence is as follows. Raw materials consisting of iron ore fines, coke breeze, slag modifiers such as lime stone, dolomite, manganese ore, lime, quartzite, and sand etc., and waste materials such ...
Optimum mean size of iron ore fines for good sintering process will vary from sinter plant to sinter plant since it is dependent on several factors but as a general rule higher mean size is better for permeability and hence helps in sintering productivity. Posted: 10 July, 2013 at 15:57 pm; Reply
