Massive hematite ore (MHO) is a special high-grade iron ore, used as lump ore in the process of obtaining direct reduction iron (DRI). The influence of porosity on the reducibility of MHO from the Capitão do Mato Mine (Iron Quadrangle, Brazil) was investigated using optical and scanning electron microscopes on drill core and open pit samples.

01-01-2015  Mueller and Segura (1975) reported that leaching a Brazilian “earthy hematite” ore sample containing 0.16% P with 10% sodium carbonate solution at 70 or 95 °C lowered the phosphorus levels to 0.05% and 0.04% P, respectively. The addition of an equal amount of sodium carbonate prior to heating at 300 °C for 1 h was also reported by Mueller and Segura (1975) to result in the lowering of ...

Types of Iron Ore: Hematite vs. Magnetite_SMM

The deposit was discovered in 1844 and ore was first mined there in 1848, as per the State of Michigan’s website. Among the four types of iron ore deposits found in this area are magnetite and hematite ore. In Minnesota, magnetite iron ore is mined mainly in the Mesabi iron range, one of the four ranges that make up the Iron Range of Minnesota.

Hematite and Itabirite - Sundance Resources Limited

Hematite is a black, grey or reddish-coloured mineral which is mined as the main source of iron. Hematite has traditionally formed the bulk of global iron ore production, and high-grade hematite is often referred to as “Direct Shipping Ore” or “DSO” because it is mined and beneficiated using a relatively simple crushing and screening process before being exported for use in steel mills.

Hematite - Wikipedia

Hematite, also spelled as haematite, is a common iron oxide with a formula of Fe 2 O 3 and is widespread in rocks and soils. Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of Fe 2 O 3.It has the same crystal structure as corundum (Al 2 O 3) and ilmenite (FeTiO 3), with which it forms a complete solid solution at temperatures above 950 °C ...
