Iron processing - Ores | Britannica
Sintering. Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together. For this purpose, a traveling-grate machine is used, and the burning of fine coke (known as coke breeze) within the ore generates the necessary heat. Before being delivered to the sinter machine, the ore mixture is moistened to cause fine particles to stick to larger ones, and then …
What Is Iron Ore Sintering? (with pictures)
Oct 27, 2019 · Iron ore sintering is a type of powder metallurgy used to pre-treat iron before using it in manufacturing applications. Sintering involves heating iron powder to partially, but not completely, melt the iron particles. The exact process used and additional elements involved vary, …
Calcination and Pelletizing of Siderite Ore | IntechOpen
As a result of experimental studies, it was found that the calcination process decreased the milling time, causing the significant energy saving and the most suitable calcination process for siderite ore was found as 15 min at 700°C temperature.

Iron ore mining and dressing - tec-science
During sintering, the fine ores are first mixed with additives and fine coke. This mixture then passes through a funnel onto a circulating moving grate. Ignition flames then set the mixed coke on fire. Due to the high temperatures, the ores “bake” together to a sinter cake (called sintering). Air vents provide a suction effect (“chimney effect”) so that the sinter cake actually bakes together over the entire cross …
Siderite - Wikipedia
Siderite is a mineral composed of iron(II) carbonate (FeCO 3). It takes its name from the Greek word σίδηρος sideros, “iron”. It is a valuable iron mineral, since …
Mechanisms in oxidation and sintering of magnetite iron ...
Apr 09, 2008 · Principal mechanisms during oxidation and sintering (dilatation) of magnetite iron ore green pellets were studied. Special attention was paid on variations in raw material fineness and green pellet porosity. Increasing fineness enhances the unwanted Duplex structures.
Sinter plant - Wikipedia
Sinter plants agglomerate iron ore fines 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. The process, called sintering, causes the constituent materials to fuse to make a single porous mass with little change in the stone properties of the ingredients. The …
