摘要

Procedure to prepare a rheological grade product of easy dispersion of a pseudolaminar silicate, product thus obtained, and methods of use of the product. A process for preparing a rheological product of a pseudolaminar silicate comprising beams of microfibers, comprising grinding the pseudolaminar silicate mineral, selected from sepiolite ore, attapulgite ore and combinations thereof, with a pseudolaminar silicate content of at least one 50%, and with a humidity of less than 40% to a particle size of less than 1 mm, mix the ground pseudolaminar silicate mineral with an aqueous solution of a dispersing component comprising at least one dispersing agent, to obtain a first mixture that It comprises 35% to 85% water, and 0.1% to 7% dispersant on the weight of the pseudolaminar silicate mineral, intensively mixing the first mixture obtained in the second stage until the microfiber beams of the pseudolaminar silicate are broken down, to obtain the rheological product in dispersion homogeneously mixed with the dispersant and water.
