HEYA !!!!!!! YOUR ANSWER+++++++++++++++++


IMPORTANCE OF CRYOLITE
*******************#*****************
IN THE EXTRACTION OF ALUMINIUM FROM ALUMINA , CRYOLITE AND FLUORSPAR PLAYS A MAJOR ROLE. WHEN WE HEAT THE ELECTROLYTE IT DECOMPOSES INTO IONS ON VERY HIGH HEATING. TO OVERCOME THIS PROBLEM, CRYOLITE IS USED TO INCREASE CONDUCTIVITY. AFTER ADDING CRYOLITE, TEMPERATURE COMES TO 900 ° C
THEREFORE CRYOLITE PLAYS A MAJOR ROLE IN EXTRACTION OF ALUMINIUM FROM BAUXITE.
