Abstract

The bentonite clays are rich in accessory minerals, the presence of these minerals, depending on the application can impact the value of an industrial warehouse, reducing its value and compromising its quality and industrial applications. Thus, the need to go through clay beneficiation processes to meet market specifications in order to use more than one hundred industrial applications. The objective of this work is to study the influence of pressure in the process of purification of hydrocycloning betonites clays: Superior Grey, Green Superior and Inferior Green District Cubati-PB performed to optimize the process of organophilization . The characterization of natural clays betonites was taken and purified at pressures of 1.5-2bar and 3-3.5bar through techniques: AG, XRD, EDX, TG and DTA. The results showed that the purification process is more efficient pressure 3-3.5bar.
