Embodiment Construction

[0019] An embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0020] The fluorite ore sorting device of the present invention is mainly composed of a rapid flotation device for coarse-grained and easily floatable minerals, a filling flotation device for medium-floatable minerals, and an intensive recovery device for fine-grained and difficult-to-float minerals. The fast flotation device includes a flotation column body 1, a downcomer 2 embedded in the upper part of the column body 1, a reflective false bottom 5 arranged at the bottom of the downcomer 2, an annular sleeve 4 surrounding the reflective false bottom 5, and the bottom of the column body 1. A foam collection tank 3 is arranged on the periphery of the top, and a feed pipe connected to a feed pump 9 is provided on the top of the downcomer 2, and a flotation bubble generator 8 is connected to the feed pipe. The fine-grained hard-to-float mineral enhanced recov...

Abstract

The invention relates to a fluorite ore sorting device and method and belongs to ore sorting devices and methods. The device comprises a coarse grain easy flotation ore rapid flotation device, a filling flotation device and a fine grain hard flotation ore strengthening collection device. The rapid flotation device comprises a flotation column, a lower guide pipe, a reflection false bottom, an annular sleeve, a foam collection tank and a bubble generator. The strengthening collection device comprises a cone, an inverted cone, a bubble generator, an ore pulp circulation pump and a lower inverted cone. The filling flotation device is a column segment between the rapid flotation device and the strengthening collection device and is provided with filler. The method includes the steps that feed ore is pressurized through a feed pump, subjected to the reaction in the bubble generator and the coarse grain easy flotation ore rapid flotation in the flotation column through the lower guide pipe, medium floatable ore is placed in the filling flotation device for further flotation sorting, and fine grain hard flotation ore is placed in the strengthening collection device for further sorting. The fluorite ore sorting device and method is high in mineralization efficiency, flotation speed and sorting efficiency and solves the problem that how to integrate the sorting of coarse grain easy flotation ore and fine grain hard flotation ore in one.

Description

technical field [0001] The invention relates to a mineral separation device and method, in particular to a fluorite ore separation device and method. technical background [0002] Fluorspar, also known as fluorspar, has a chemical composition of CaF 2 (Ca:F=51.33:48.67), is an important fluorine-containing mineral in nature. The main fields of application of fluorspar are chemical, glass, steel, aluminum smelting and cement industries. In addition, fluorite is also widely used in medicine, ceramics, electrical machinery, aviation and other fields. Fluorite is one of the main mineral components in ore. It exists in various ore types and intercalates with all minerals. Single fluorite ore is mainly produced in the form of veins, fine-grained aggregates and coarse grains. The embedded particle size of fluorite is relatively coarse, but medium-sized particles account for the majority. In a single fluorite ore, a large part of it is difficult to separate the ore minerals fro...
