clear trend toward the production of increased quantities of sandy alumina. In Russia, due to a lack of bauxite, a process using nepheline as feed-stock has been used to produce alumina. Essentially the technique consists of sintering a nepheline ore, or concentrate, with limestone. The resultant sinter-cake consists of sodium and potassium
