Hematite: A primary ore of iron and a pigment mineral
Many of the sedimentary iron deposits contain both hematite and magnetite as well as other iron minerals. These are often in intimate association, and the ore is mined, crushed, and processed to recover both minerals. Historically, much of the hematite was not recovered …
Hematite Processing by Flotation
Low grade deposits containing specular hematite (Fe2 O3) as the major iron mineral as low as 25% Fe can be treated with “Sub-A” Flotation to produce concentrates that average better than 62% Fe with less than 9% SiO2 and with a high recovery.
Hematite - an overview | ScienceDirect Topics
Most of the high-grade hematite iron ores (direct shipping ore (DSO)) are subjected to simple dry processes of beneficiation to meet size requirements. This involves multistage crushing and screening to obtain lump (− 31.5 + 6.3 mm) and fines (approximately − 6.3 mm) products.
Iron ore - Wikipedia
Increasing iron ore demand, coupled with the depletion of high-grade hematite ores in the United States, after World War II led to development of lower-grade iron ore sources, principally the utilization of magnetite and taconite. Iron-ore mining methods vary by the type of ore being mined.

Types of iron ore: Hematite ore. Hematite ore is a direct-shipping ore with naturally high iron content. Because of its high iron content, hematite ore must undergo only a simple crushing ...
Hematite - Wikipedia
Hematite is colored black to steel or silver-gray, brown to reddish-brown, or red. It is mined as the main ore of iron. Varieties include kidney ore, martite (pseudomorphs after magnetite), iron rose and specularite (specular hematite). While these forms vary, they all have a rust-red streak. Hematite is harder than pure iron, but much more brittle.
