Different Types of Iron Ore - Mineral Processing & Metallurgy

Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times high-grade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration.

Pre-concentration relies on heterogeneity in the ore. That is, at some scale, there must be discrete higher-grade and lower-grade zones in the ore that have the potential to be separated. For example, there may be discrete veins of valuable minerals within poorly mineralized host-rock or sulphide breccias containing clasts of unmineralized rock.
