PROCESS
There is provided a method for reducing the amount of silica in a desert sand of a type that also comprises calcium carbonate, iron oxide and alumina components, to thereby produce a cement raw material feedstock, the method comprising: imparting a net negative electrical charge to a silica component and a net positive electrical charge to a calcium carbonate component of the desert sand through interparticle friction by a triboelectrostatic mechanism; and applying an electric field to the charged components of the desert sand by a triboelectrostatic mechanism; such that the negatively charged silica component is separated from a remainder of the components of the desert sand to thereby produce the cement raw material feedstock.
