It concluded that it would use a froth flotation separation method employing an amine reagent for floating the sylvite. Although defendant's process was to be somewhat different 6 plaintiff believed from the very beginning that no successful froth flotation method could be successfully used without infringing its patents. It so advised the ... Flotation Frothers What is the Function of Frothers. The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the non-floatable minerals. Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form.

Introduction to Mineral Processing. Froth Flotation Froth flotation is considered to be the most widely used method for ore beneficiation. In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer ... Remarks Froth flotation is used to reduce pyrite in English coals; the flo- tation of coal refuse to obtain salable pyrite is uneconomical in view of today's poor sulfur market; if ethyl xanthate is used as the collector, it is aborbed into coal pyrite in such a manner as to make it ineffective for flotation.

The froth flotation process separates the zinc sulfide from the rest of the ore. The froth flotation is divided up into cells, which usually cascade onto each other to further concentrate the zinc. Each cell is filled with water, ground ore, and collector chemicals such as xamthates, dithiophosphates, and/ or thionocarbamates (Orcia). 570 Development of KYF Flotation Cells 571 Research of Froth Flotation Equipment 572 R&D and Application on CLF Flotation Machine 573 Determination of Mineral Processing Flow Sheet in Yichun Tantalum-niobium Mine 574 Research on Dissolved Air Flotation System for Fine Mineral Concentration 575 The Automation Design of Mica-paper Producing Line
