Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace. The final product, a sinter , is a small, irregular nodule of iron mixed with small amounts of other minerals.
Agglomerate is a material composed of iron oxides and gangue, roasted and sintered [notes 1] [1] in an agglomeration plant. This product is obtained by burning coal previously mixed with iron ore and oxides. This conditioning of iron ore optimizes its use in the blast furnace.
Sintering or frittage is the process of compacting and forming a solid mass of material by pressure [1] or heat [2] without melting it to the point of liquefaction. Sintering happens as part of a manufacturing process used with metals, ceramics, plastics, and other materials. The atoms/molecules in the sintered material diffuse across the ...
Sinter plant, in which iron-ore dust gets mixed with other fine materials at high temperature, to create a product – sinter – for use in a blast furnace; Sintering, a high temperature process for fusing powder together; Calcareous sinter, calcium carbonate deposited by springs; Siliceous sinter, silica deposited by hot springs and geysers
In 1926, an industrial pilot plant was constructed by Krupp in Rheinhausen to explore the potential of this pelletizing technology. However, the plant was later dismantled to make way for the installation of a large-scale grate sintering line, which emerged as a competing process in the industry. [4]
Plants for the production of lead are generally referred to as lead smelters. Primary lead production [clarification needed] begins with sintering. Concentrated lead ore is fed into a sintering machine with iron, silica, limestone fluxes, coke, soda ash, pyrite, zinc, caustics or pollution control particulates.

Sinter roasting involves heating the fine ores at high temperatures, where simultaneous oxidation and agglomeration of the ores take place. For example, lead sulfide ores are subjected to sinter roasting in a continuous process after froth flotation to convert the fine ores to workable agglomerates for further smelting operations.
