India Iron Ore Fines Risk of Liquefaction

Oct 10, 2007 India: Iron Ore Fines - Risk of Liquefaction. In the past few weeks three vessels have experienced serious cargo liquefaction problems after loading iron ore fines in Mangalore and Haldia. The iron ore fines were apparently loaded from open stockpiles which had been exposed to heavy rain. Two of the ships developed a severe list on passage and ...

Liquefaction is a phenomenon in which a soil-like material is abruptly transformed from a solid dry state to an almost fluid state. Many common bulk cargoes, such as iron ore fines, nickel ore and various mineral concentrates, are examples of materials that may liquefy. If liquefaction occurs on board a vessel, the stability

The transportation of iron ore fines has increased massively since the process of sintering – that is, coagulating iron ore fines with coke to enable their use in the blast furnace – came of age in the late 20th century. Before sintering became common, just 10-20% of all iron ore produced was used. The rest – fines and micro-fines – was ...

Experimental Study on the Liquefaction Mechanism of Iron

The liquefaction of Iron Ore Fines (IOF) during maritime transportation has got more attention in recent years. To study its liquefaction mechanism, the undrained monotonic loading tests on saturated IOF were conducted by using compression tri-axial apparatus. The static liquefaction behaviors of IOF under different densities and confining pressures were investigated.

Jul 04, 2021 Iron ore containing BaSO4 may have a series of effects on the quality of the sinter and performance of the blast furnace. Thus, the effect mechanism of BaSO4 (0–6.0 mass%) on the compressive strength, mineral composition, and microstructure of the sinter was investigated. The experimental results show that the compressive strength of the sintered samples initially increases …
