Nov 21, 2014· Chemical reactions during sintering results into formation of sinter cake which is a multiphase material with a heterogeneous microstructure. It is composed of several mineral phases out of which main phases are hematite, magnetite, iron ore, SFCA, dicalcium silicate and a glassy phase.
The following is an introduction to these four types of iron ore, magnetite, hematite, limonite and siderite. Iron ore property. Iron is widely distributed in nature (the crust), but since iron is easily combined with other elements to form various iron minerals (compounds), there is little natural pure iron .

Hematite is economically the most important iron ore, since it is more abundant than magnetite. Hematite typically occurs as one of two varieties; a massive red earthy form or a black specular variety that has a strong metallic luster. The latter variety may be mistaken for magnetite, but is not magnetic.
