Section snippets Materials. This study was conducted using a magnetiterich iron ore sourced from South Australia. The asreceived sample had particles with a top size of 32 mm and 80% passing (P 80) ore was crushed using a single toggle jaw crusher to generate a product with a top size of 10 mm to meet the requirement of the HPGR.

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 goethetichematite 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 containing below 45 μm is mostly brittle ...

Experimental results show that grade of iron ore fines was enhanced by % in single stage operation with reasonable yield. Experimental results indicate that SBAFS has a huge potential for iron ore fines beneficiation with the added advantage of the reduction of water consumption during the beneficiation process.

iron ore is expected to rise by more than 200 million tonne per year to meet the internal demand export. This additional requirement of iron ore will need beneficiation of low grade ore/fines to get the major portion of increased demand. This paper deals in brief to use of available methodologies for beneficiation of iron ore in Indian context.

The beneficiation process refers to the production process in which the mined ore undergoes various operations to obtain a concentrate that meets the smelting requirements. The beneficiation process mainly includes: ore crushing and screening, ball mill grinding and classifier classification, mineral separation (gravity separation, flotation ...

Rough processing of iron ore employs dry methods which means that equipment is tuned to process large particles, but fine magnetic material less than a few tenths of a millimeter in size is not separated as efficiently. The relevance of this study is determined by the fact that dry beneficiation waste contains recoverable ironbearing magnetite of commercial value.

In mining and minerals industries, whenever water supplies are restricted and also where wet processing leads to problems in handling and dewatering of the products and tailings, dry beneficiation is preferred. Moreover, the decrease in available highgrade iron ores has generated a need to develop alternative beneficiation processes for processing lowgrade iron ores.
