refractory properties, plays an important role in steel making industries. There are some andalusite
deposits in the country, on which recently extensive exploration activities have been carried
out. However, beneficiation investigations on these deposits are limited.
In the the results of present paper, benificiation studies, performed on Sartal deposit,
located atsouth of Khorasan province, have been presented. The main goal was to up-grade Sartal
andalusite to, at least, 55% AzI03 and less than 1 % Fez 03 content, which can be sold in the
market.
The raw materials contained 18-19% Alz °3, 2-3% FeZ03, 4% FeO and 61.62% Sial. The
major mineral was amlalusite, while mica, quartz and iron minerals were the main impurities.
The feed material was deslimed at - 500 ,urn and then treated by various separation methods.
The results showed that high intensity magnetic separation and then heavy media separation can
up-grade the Sartal and produce a desirable product. Finally, a 11owchart has been suggested, which can be used for economical evaluation.
