Abstract:
The invention concerns a process for the preparation of aqueous suspensions of fluid mineral matter, which are able to be pumped and conveyed by the end user immediately after the filtration stage, possibly followed by a compression, which process comprises filtration in two separate stages.The invention also concerns aqueous suspensions of mineral matter obtained and their uses.
