Selective Flotation of Calcite from Fluorite: A Novel Reagent Schedule
Abstract: Fluorite is an important strategic mineral. In general, fluorite ores will contain a certain amount of calcite gangue mineral. Thus, they need to be separated from each other. For an economic separation, a reverse flotation process is used to float calcite gangue from fluorite. However, little information on the separation is available. In this study, a novel reagent schedule using ci...
متن کاملSinglet Oxygen: a Reagent in Organic Synthesis
In the introduction, the generation, the electronic state and the reaction of singlet oxygen (102) with carbon—carbon double bonds is described. For preparative purposes, 102 is generated by dye-sensitized excitation of oxygen (02). The photo-oxygenation reaction leads to the formation of peroxides, which can be used as intermediates in the organic synthesis. Described are processes of preparat...

متن کاملFlotation of Biological Materials
Flotation constitutes a gravity separation process, which originated from the minerals processing field. However, it has, nowadays, found several other applications, as for example in the wastewater treatment field. Concerning the necessary bubble generation method, typically dispersed-air or dissolved-air flotation was mainly used. Various types of biological materials were tested and floated ...
