Beneficiation of Clay-Rich High-LOI Low-Grade Iron Ore
The unutilized iron ore fines (IOF, − 10 mm, 45% to < 60% Fe(T)) left at various mine sites during blasting and processing are rich in goethetic-hematite associated with high clay and considered a potential iron ore resource. The variation of loss on ignition (LOI) from mines to mines is based on the goethite and clay mineral content. The clay Most of the high-grade hematite iron ores are typically subjected to simple dry processes of crushing and classification to meet the size specifications required for direct shipping ore (DSO). This involves multistages of crushing and screening to obtain lump (−31.5 + 6.3 mm) and fines (approximately −6.3 mm) products.Comminution and classification technologies of iron ore

The Challenge of Domestic Iron and Steel
The ore deposits obtained from Dunoka, Amankwo and Umuakpo in Lejja Nsukka were found to be iron silicate in nature. They were analysedby XRD, XRF, AAS and the ores were found to contain 60.59% Essar Steel is setting up an iron ore beneficiation plant at Dabuna to upgrade the quality of low-grade iron ore fines from 45 to 54 % to over 63 % Fe content and a 253-km slurry pipeline connecting Dabuna and Paradeep.

List of Some Nigerian Iron Deposits and Locations
The iron ore has to be beneficiated at the rate of eight (8) million tonnes per year by NIOMCO to supply 2.15 million tons of 63 % to 64 % grade concentrate of iron (Fe) per year to Ajaokuta SteelThe haematite ore in South Africa is processed in a dry process to a HQ lump ore with 64 % iron content and a sintered fine ore with 63.5 % iron content. For fine ore beneficiation, wet processes are used.

A Study on High-Grade Iron ore Beneficiation to Reduce
Iron ore pellets are largely characterized by inherent physical and chemical properties of the ore. Alumina and silica play important roles in determining the productivity of a Blast Furnace. On average, one percent increase in iron content improves productivity by 2% and reduces coke consumption by 1%. Therefore higher iron ore feed content to This study present the system-level dynamic performance and techno-economic optimisation of solar-thermal beneficiation of iron ore. Fig. 1 illustrates the schematic diagram of the dynamic model for the proposed solar-thermal beneficiation plant. The whole process is composed of the following units: the air-based PTC, the rock-bed Solar-thermal beneficiation of iron ore: System-level dynamic
