A specific test carried out as a measurement of value, such as the crushing strength of fired pellets, is only as good as the degree of reproducibility of the test. Results of Laboratory Pelletizing Tests. The laboratory tests were carried out on five different iron ore concentrates, designated as M1, M2, M3, and H1, H2.

The following Iron Ore specifications guide contains the primary specifications and methodologies for Platts Iron Ore assessments throughout the world. These are the timestamps used for Platts iron ore assessments. Data reported at or after these timestamps is not considered in the assessment process. Asia: 5.30pm Singapore
Iron ore is the primary raw material used to make steel. Steel is strong, longlasting and costefficient making it perfect for everything from washing machines to cars, bridges and skyscrapers.
Crushing. Asmined iron ore contains lumps of varying size, the biggest being more than 1 metre (40 inches) across and the smallest about 1 millimetre (0.04 inch). The blast furnace, however, requires lumps between 7 and 25 millimetres, so the ore must be crushed to reduce the maximum particle size. Crushed ore is divided into various fractions
Iron ore pellets are sintered, centimetresized spheres of ore with high iron content. Together with carbonized coal, iron ore pellets are used in the production of steel.

Without iron ore, QM had the highest crushing strength, which was 92.25%. When the addition amounts of iron ore were 10% (QE1) and 20% (QE2), the ferrocoke could maintain a higher crushing strength, which were 78.94% and 72.11%, respectively. When the addition amount of iron ore was 30%, the crushing strength of
Iron ore is the key raw material for steel production enterprises. Generally, iron ore with a grade of less than 50% needs to be processed before smelting and utilization. After crushing, grinding, magnetic separation,
