The iron ore lump premium price
The Platts spot iron ore lump premium assessment by S&P Global Commodity Insights (IOCLP00) is of the premium a lump cargo commands over the price of fines as defined by the Platts 62% Fe Iron Ore Index, or IODEX. This premium is assessed on a US dollar per dry metric ton unit CFR Qingdao basis, which is applied over the IODEX assessments. ...

From Iron Ore to Crude Steel: Mass Flows Associated with Lump…
Iron ore is prepared for subsequent steps in three forms: as lump ore (6–30 mm size), pellets (9–16 mm), and sinter (15–25 mm). Lump ore is used when the ore grade is relatively high, and requires no processing except crushing and screening, although some simple separation such as washing of fine particles may be done.

lump ore samples were reduced very slowly and the disinte-gration of lump ore samples was not obvious. The samples' average diameter (weighted average of particle size distribu-tion) decreased from 12.75 mm to 11.71 mm. In the second step, the reduction degree of lump ore samples still kept at low level, but RDBI-6.3 increased sharply. The ...
