The constituent minerals in these low-grade iron ore are mostly hematite and quartz, and they are liberated at extremely fine sizes due to the intergrowth of hematite and quartz. During the mining of hematite ores, large quantities of such low-grade ores are generated and kept unutilized due to the lack of appropriate beneficiation technologies.

Very high purity quartz deposits are extremely rare. Quite often the quartz needs a prior enrichment to be used for advanced high-tech applications. In industrial minerals, quartz is often associated with feldspar, and other silicates and oxides minerals which These last affect strongly affect their properties and performance [3].
