Fines drive the iron ore price and it makes up the bulk of supply, but producers of so-called "lump" ore enjoy a little more breathing room. Lump ore can be loaded directly into blast furnaces

When iron ore is crushed and divided to lump and fines parts, there are principled differences between the lump and fines degrees. The lump products are richer in iron and lower in the other impurities in comparison with the fines product. The grade differences between lump and fines, added with the lump percentage, are known as the 'lump algorithm'. We offer high grade iron ore lump according to the

Circored fine ore direct reduction | Dirk Nuber - Academia.edu. Its use for the direct reduction of iron ore fines commenced in the late 1970s and was as a result of the significantly increasing price difference between r Fig.1 View of Circored Plant in Point Lisas, Trinidad fine ore and lump ore or pellets. .

Iron ore also differs in physical form. Fines require sintering (agglomeration into crude pellets) prior to use in the blast furnace. Lump ore can bypass this process and be charged directly into the furnace, as can pellets, and both command an associated price premium.

08.12.2020· In iron processing: Lumps and fines As-mined iron ore contains lumps of varying size, the biggest being more than 1 metre (40 inches) across and the smallest about 1 millimetre (0.04 inch). The blast furnace, however, requires lumps between 7 and 25 millimetres, so the ore must

Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities. The results, high-quality fine ore powders, are known as fines. Magnetite. Magnetite is magnetic, and hence easily separated from the gangue minerals and

Iron Ore Fine. Iron ore fines refer to a small particle of high grade direct ship ore. Fines are high quality ground iron ore sands that must be sintered at first to create larger pieces before they can be used in blast furnaces. The grade is between 56% to 66% iron (Fe) with the disadvantageous elements controlled through ore mixing.
