摘要

萤石是一种重要矿物，主要用于生产氢氟酸。这种矿物需要浮选增值。为了改进该技术，了解其吸附的物理化学机理是非常重要的。因此，本研究的目的是对单宁酸在萤石表面的吸附进行实验研究。获得的结果首先允许达到最佳粒度。然后利用等温线模型确定单宁酸在萤石上的吸附机理。

Experimental stuy of tannic acid adsorption on fluorite surface: particle size effect and isotherm modelling

Fluorite is an important mineral used mainly to produce hydrofluoric acid. This mineral requires flotation valorization. To improve this technique, it is so important to understand its adsorption physicochemical mechanism involved. Therefore, the objective of this work is to investigate an experimental study of tannic acid adsorption on fluorite surface. Obtained results allowed firstly to achieve optimal particle size. These results were then exploited to determine tannic acid adsorption mechanism onto fluorite by isotherm modelling.
