Iron Ore Tailings Dewatering: Measurement of Adhesion and Cohesion for Filter Press Operation

Globally, mining operators focus increasingly on tailings filtration to recover process water and store more safely. Generally, required contents below 20-w% are reached by using filter presses. To maintain high efficiency, complete cake detachment is needed because incomplete discharge reduces plant performance. However, can occur in different ways, mainly influenced adhesion of the cloth as well cohesion cake. Therefore, this study points out major behaviors a theoretical approach describe them. Furthermore, investigations iron ore filtrations were carried show influences media, pressure post-treatment cohesion.
