Process for the recovery of micas by flotation and micas thus obtained |
摘要 |
The invention relates to a process for the recovery of micas by flotation starting with slurried ore from which the fines have been optionally removed, comprising a stage of bringing the said slurry into contact with an appropriate cationic collector, followed by an actual flotation stage and recovery of the supernatant formed for subsequent treatment and optional rewashing, characterized in that it is carried out at a pH higher than 6 and in that the stage of bringing the said slurry into contact with the cationic collector is preceded by a stage of bringing the said slurry into contact with an activating agent chosen from soluble metal salts. The invention also relates to the micas obtained by the process.
