Washing Of Iron Ore Lumps

Impact of quality of iron ore lumps on sustainability of ...

2015-1-1  The quality of lumps may have a significant impact in iron ore mining systems with implications for mineral reserve recovery rates. Improving the quality of lump ore, through a simple yet innovative mineral processing, can maximize recovery of reserves, decrease waste generation, and increase the productivity and sustainability of mines by allowing transition to lower quality iron ores.

Estimating the lump to fines composition split in iron ore ...

2014-5-13  have different lump algorithms. Some ore geotypes give a greater percentage of lump, or show a greater lump to fines composition difference than do other types of ore. Some geotypes even tend to split according to a “reverse algorithm”, with the lump component being lower in iron and higher in silica and alumina than is the fines component.

Iron Ore Processing Plants - Iron Ore Wash Plants - CDE

Iron Ore. Efficiently remove silica and alumina contamination to increase efficiencies in steel production. Our iron ore wet processing plants are proven to successfully deal with silica and alumina contamination in the iron ore, resulting in an increase in the Fe value of the iron ore thereby increasing the efficiency of the steel production process.

Calibrated lumps for DRI - CDE Global

Calibrated lumps for DRI. Iron production through DRI (Direct Reduced Iron) route is a very controlled process which requires the Iron-ore feed to be in the range of 5mm – 18mm. Presence of particles finer than this creates problems in the kiln in the form of accretions in the kiln walls and also higher consumption of coal fines.
