Natural minerals and divided solids: methodology for understanding surface phenomena related to industrial uses and environmental problems

This introductory paper aims at presenting the series of articles in this special issue of Comptes Rendus Geoscience voted to the study and use of natural minerals. The research methodology that can be applied to the investigation of surf phenomena related to adsorption, exchange and retention onto the surface of natural minerals and divided solids is presented special focus is given to the retention of surfactant molecules, in view of their considerable importance in numerous industrial fields, such as, far instance, mineral flotation and enhanced oil recovery, Throughout this introductory paper; relevance of this research approach to the field of geosciences is stressed by listing various applications where it can provide conclusive answers, especially for environmentally related issues.
