Silica sand low in iron is much in demand for glass, ceramic and pottery use, and for many of these applications clean, white sand is desired. Impurities such as clay slime, iron stain, and heavy minerals including iron oxides, garnet, chromite, zircon, and other accessory minerals must not be present.
In this step, it is commonly evaluated if the ore can be concentrated (beneficiated) by screening, where the enrichedsilica fraction is separated from the ore. The product from the beneficiation step is fed to the autoclave. Sulfuric acid leaching of limonite is performed at high temperatures (240270°C) in acid resistant titanium lined ...
