Iron is one of the most important and troublesome impurities in silica sand and the presence of Fe 3+ oxides leads to unwanted reddish and yellowish color changes on the quartz and damages its property greatly [9,10,11,12]. If the quartz mineral contains less than 50 μg/g of impurities, these quartz minerals are called high-purified quartz.
