Since bauxite is a naturally occurring mineral, it has a number of impurities, like iron, silica, Titania, calcium, and small quantities of phosphorous, sulfur, zinc, magnesium and various carbonate and silicate minerals. These impurities not only create quality problems, but also increase production costs, besides causing environmental pollution.
