Magnetite - an overview | ScienceDirect Topics
Figure 9.8 presents a typical flow sheet for processing a magnetite ore using multiple stages of low-intensity magnetic drum separators. The ore consists predominantly of magnetite and quartz. There are three stages of ball mill grinding and magnetic separation, using low-intensity magnetic drum separators to reject quartz as early as possible.
magnetite compressive strength
The compressive strength of magnetite concentrate pellets with different proportions of oolitic haematite ore was investigated. The porosity of finished pellets was determined to clarify how oolitic haematite ore affects the compressive strength. The main findings are summarized as follows. The compressive strength of pellets decreases gradually.
Unconfined Compressive Strength Iron Ore

Magnetite Iron Ore Concrete for Nuclear Shielding
Discusses crushing and handling of the magnetite iron ore, which was used as the aggregate for a dense shielding concrete, and the physical properties and costs of magnetite ore concrete are compared to those of other concretes. The mix used had a compressive strength of 4000 psi in 10 days.
What is the compressive strength of iron ore - Answers
Iron ore is a catch-all name that covers a variety of different ores of iron. Compressive strength, depending on the particular ore, can be from, say, 7MPa or even so small that the ore falls apart before it can be measured, up to 680MPa and beyond.
The Study of Pelletizing of Mixed Hematite and Magnetite Ores
The present study aims to investigate the use of mixed hematite and magnetite ores in iron ore pellet production. Pelletizing tests were carried out on the hematite and magnetite premixed pellet feed.
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.
Recrystallization of Fe O During the Induration of Iron ...
hematite grains, and consequently the Fe 2 O 3 crystallites are easily formed between particles. It also can be found that the compression strength of roasted pellet increases with magnetite ratio below 70%; above 70%, the strength will be decreased with the addition of magnetite.

Iron ore pelletization - ScienceDirect
The compressive strength of preheated pellets is increased further to 500 N per pellet even at a lower preheating temperature of 1050 °C when a blend comprising 30% magnetite concentrate and 70% specularite concentrate is pretreated using an HPGR. This meets the minimum requirement for a rotary kiln and the preheating time can be shortened.
Magnetite - Wikipedia
Small grains of magnetite occur in almost all igneous and metamorphic rocks. Magnetite is black or brownish-black with a metallic luster, has a Mohs hardness of 5–6 and leaves a black streak. The stone IUPAC name is iron(II,III) oxide and the common stone name is ferrous-ferric oxide .
