Reverse flotation for removal of silicates from diasporic ...

Aluminum-silicates such as pyrophyllite, illite, kaolinite and chlorite are impurity minerals in diasporic-bauxite, it being necessary to remove these silicate minerals to improve the mass ratio of Al 2 O 3 /SiO 2 of diasporic-bauxite for the Bayer process. A new quaternary ammonium salt (DTAL) has been shown to be efficient in the flotation of these silicates.

ALUMINA EXTRACTION FROM ALUMINO-SILICATE ORES AND ...

Mar 28, 1972 · Alumino-silicate ore and a potassium sulfate bearing ore such as polyhalite or langbeinite are reacted by reducing and then calcining. Reduction decomposes the reactants and produces H 2 S. Calcining produces a sinter containing potassium aluminate and silicates. The aluminate is leached from the sinter with KOH and/or K 2 CO 3 solution and then precipitated to .

Zirconium(IV) silicate - Wikipedia

Zirconium silicate occurs in nature as mineral zircon. Ore is mined from natural deposits and concentrated by various techniques. It is separated from sand by electrostatic and electromagnetic methods. Also, the compound can be made by fusion of SiO 2 and ZrO 2 in an arc furnace, or by reacting a zirconium salt with sodium silicate in an ...

The Extraction of Iron - Chemistry LibreTexts

Removal of other elements: Elements like phosphorus and silicon react with the oxygen to form acidic oxides. These are removed using quicklime (calcium oxide) which is added to the furnace during the oxygen blow. They react to form compounds such as calcium silicate or calcium phosphate which form a slag on top of the iron.
