Developments in iron ore comminution and classification

1/1/2015· The iron ore in this area contains a large volume of fines (20-30% below 150 μm), which can be transformed by high moisture content into a sticky mass that is almost impossible to screen Vale initially considered wet-process screening using water sprays to overcome the problem but ultimately rejected that approach as too costly.

LOW UNIT VALUE OF IRON ORE The major iron-ore producers of the world mine massive high-grade ore-bodies, and sell their products after only crushing and screening of their run-of-mine ore Without thesace ofore reserves, this is not possible with South.

Precautions against bulk cargo which may liquefy

Mill Scale, a by product of hot rolled steel-making, is a bulk commodity liable to liquefaction, like iron ore fin Mill Scale and Mill Scale Fines possess a transportable moisture limit (TML) and have thus been confirmed as Group A cargoes, which should not be accepted for loading without the shipper having certified the moisture content and TML.

SOLID BULK SHIPPING: CARGO SHIFT, LIQUEFACTION AND THE TRANSPORTABLE MOISTURE

If some solid bulk cargoes such as concentrates, unprocessed nickel ores and iron ore fines contain sufficient moisture, then cargo compaction during a voyage may cause liquefaction This has been known to result in major cargo displacement (‘cargo shift’), causing the vessel to.

Iron Ore Beneficiation

There is a large economic competitive advantage in beneficiating iron ore in the dry state, as this avoids the costs of removing the moisture that is added during wet processing However, dry beneficiation presents more technical challenges than wet systems, due to the greater difficulty in maintaining dynamic stability and the complexity of a dry solids handling system.

Dry Processing

Today, most of our iron ore production (about 60%) is through dry processing The natural moisture processing is used at Carajás and Serra Leste mines, at S11D Eliezer Batista complex, in Pará, and at several plants in Minas Gerais.
