Determining Iron Grades of Ores or Concentrates

2020-2-18 Usually, earth crustal rocks contain some iron in their composition. Iron minerals are abundant in nature and they include magnetite, hematite, siderite, and pyrite.[2,3] Pyrite is the most well-known iron sulfide ore and it occurs in rocks of every geologic age and of virtually every geologic realm.

The result has seen much wider and more volatile differentials between iron ore indices of different grades, and companies exposed to prices such as the high-grade MBIOI-65-BZ and MBIOI-CO are now calling for exchanges to list contracts settled against those indices to help manage price risk, with the basis risk to the 62% Fe financial benchmark deemed unmanageable.

iron processing Ores Britannica

The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe 2 O 3), which is red; magnetite (Fe 3 O 4), which is black; limonite or bog-iron ore (2Fe 2 O 3 ·3H 2 O), which is brown; and siderite (FeCO 3), which is pale brown. Hematite and magnetite are by far the most common types of ore.

2018-12-31 In 2018, Australia's EDR of iron ore increased by 3% from 2017 to 49 604 Mt (Table 3). Similarly, there was a 4% EDR increase of contained iron to 24 122 Mt (Table 4). EDR attributable to magnetite deposits have decreased by 1%, likely due to re-assessment of projects and inactivity in the magnetite industry.

Determining Iron Grades of Ores or Concentrates

2020-2-18 The iron grade of a high pyrite-containing ore was determined by the new method, and the results were compared to those obtained by the traditional roasting or HNO3 titration. The new method was found to provide iron grade values close to the roasting method. The proposed method was tested on a number of samples with known iron grades.
