Iron ore (fines) - Cargo Handbook - the world's largest ...

Description. Iron Ore (fines) Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite (FeO(OH)), limonite (FeO(OH).n(H 2 O)) or siderite (FeCO 3).

IMSBC CODE (S-7 to S-13) – Capt.S.S.Chaudhari

The correct pressure to be applied is calculated from: Tamping pressure (Pa) = Bulk density of cargo (kg/m 3 ) x Maximum depth of cargo (m) x Gravity acceleration (m/s 2) The number of tamping actions should be about 35 for the bottom layer, 25 for the middle and 20 for the top layer.

A Logical Approach to Determination of Density and ...

The importance of the accurate determination and interpretation of the bulk density and porosity of a given iron ore deposit is very often disregarded or neglected. Large amounts of time and money are spent on delineating and testing orebodies, and yet one of the most important factors in resource evaluation is sometimes estimated or, at best, determined from existing data from similar deposits.
