Fluorite is known as it can emit light when it is subjected to friction, heating, ultraviolet radiation, etc. Its main element is calcium fluoride (CaF₂). The mineral comes from volcanic magma. During the cooling process of the magma, the gas solution separated by the magma contains fluorine. In the curse of the solution rising along the stone cracks, the fluoride ions in the gas solution combine with the calcium ions in the surrounding rocks, then after cooling and crystallization, fluorite forms. In industry, fluorite is the main source of fluorine. It can be extracted to produce fluorine and various compounds. Fluorite is generally an associated mineral. For example, fluorite concentrate can be got from the tungsten tailing. Popularly, the fluorite concentrate adopts a "concentration - filtration" two-stage dehydration process.
What are the characteristics of fluorite concentrate? Compared with other concentrates, the particles of fluorite concentrate are very fine. Most particles are under 40 microns, and even the particles below 10 microns also occupy a larger share. In addition, associated minerals will also increase the difficulty of mineral dewatering. For example, in the process of tungsten flotation, due to the addition of sodium silicate, the particles will be distributed as suspension. Therefore, there are higher requirements for dehydration equipment. At present, the chamber membrane filter press is widely used as dewatering equipment in this field. Since the squeeze pressure is higher than the feed pressure, 10% cake moisture can be finally obtained after the secondary pressing by the membrane filter plates. If use our cross blow function, the moisture of the filter cake can be further reduced. Please consult Yuwei Filter to select the appropriate filter press type and model to meet your mineral dewatering.
