Abstract (en)
[origin: WO2022139760A2] The subject of the invention relates to a clay filtration method, which allows the use of a raw material with increased weight per liter by preserving the chemical properties of especially the fine-grained clays with high plasticity, enables filtration times for the same to be reduced, and relates to the filtered clay obtained by said method. The clay filtration method according to the invention basically comprises the process steps of dispersing the clay in water in the presence of at least one first agent that enables the clay grains to diverge by sliding over one another and filtering the clay in the presence of at least one second agent that enables the clay grains to converge to thereby easily release the water in their structure.
