Flotation process summary Currently the most widely used is the froth flotation method. Crushed ore and pulverized to make a variety of minerals dissociate into single particles, the particle size and meet the requirements of the flotation process. Various kinds of flotation reagents are added to the milled pulp and stirred and blended to act with mineral particles to expand the difference in floatability between different mineral particles. The adjusted slurry is sent to the flotation tank and stirred for aeration. The ore particles in the slurry contact and collide with the bubbles, and the floatable particles selectively adhere to the bubbles and are carried to rise into a mineralized foam layer composed of gas-liquid-solid three-phase, mechanically scraped or The slurry surface overflows, then dehydrates and dries into a concentrate product . Mineral particles such as gangue that cannot be floated are discharged as tailings products from the bottom of the flotation tank with the slurry. Sometimes, the unwanted floating mineral particles, mineral particles remain in a useful pulp, called reverse flotation, such as quartz emerges from iron ore and the like. Conventional froth flotation is suitable for sorting ore particles of 0.5 mm to 5 μm, depending on the particular mineral . A special flotation method is required when the selected particle size is less than 5 μm. For example, flocculation-flotation is to use flocculant to flocculate the useful minerals of the fine particles into larger particles, and then remove the coarse-grained gangue after the fine mud is removed. The carrier flotation is carried out by using the ore particles having a particle size suitable for flotation as a carrier, so that the fine ore particles adhere to the surface of the carrier and are then floated and sorted. Also useful oil agglomeration of the fine ore particles of flotation and flotation oil emulsified agglomeration flotation; and high temperature chemical reaction the metal ore and then converted to a metal mineral flotation segregation flotation. When the metal ions in the aqueous solution are recovered by froth flotation, they are first chemically precipitated or adsorbed by an ion exchange resin, and then the precipitate or resin particles are floated. The materials in the size of molecules, ions and colloids are treated and separated by floating foam. It is characterized by the hydrophobicity of certain materials, slow agitation and a small amount of aeration, so that the floating foam gathers on the surface of the water to scrape. Such as the recovery of oil, protein, pulp and chemical products from the water. Ion flotation is the separation of the reaction product into the floating foam under the action of a surfactant capable of precipitating or complexing with ions. The non-foaming flotation is to separate the flotation material after water-gas, organic liquid-water, water-oil interface (or surface) extraction and aggregation. For example, early film flotation, full oil flotation; developing liquid-liquid extraction flotation. Oil pellet sieving is the formation of selective pellets of hydrophobized useful mineral particles with oil followed by sieving . The bubbles required for flotation are firstly produced by boiling slurry or chemical reaction; currently, mechanical agitation is used to inhale air or introduce compressed air to foam, and decompression or pressurization followed by decompression foaming and electrolytic foaming. There are many factors related to the flotation effect. In addition to the nature of the ore, the flotation agent, flotation machine and flotation process are the most important. The theoretical basis of various suspension processes is generally the same, that is, the mineral particles can aggregate at the liquid-gas or water-oil interface due to the hydrophobic properties of the surface or the hydrophobic (affinity or oil) properties obtained by the action of the flotation agent. .
