| Abstract |
| The amenability towards beneficiation by conventional
technique of off-grade magnesite from Salem containing
Si02 as contaminant is not good. Winning of magnesia
from sea water is very much capital intensive. Investigation
carried out for upgrading off-grade magnesite following
a new technique yielded promising result. Operating
variables connected with the new approach were studied
in detail and elaborated in the present paper. Following
the new approach it has been possible to recover more than
80% magnesia of 94% purity with less than 3% silica
content (cal:lned basis) from magnesite containing more
than 10% silica (calcined basis). |
