ABSTRACT:
The invention relates to a process for upgrading andalusite present in an ore containing it. The process involves separation from other silicates by froth flotation to obtain a concentrate whose content of andalusite is higher than 90%. It is characterized by the fact that the process comprises at least the following steps:
