Flotation application range During the flotation process, the ups and downs of minerals are almost independent of mineral density. Such as brass and mineral quartz, the former density of 4.2, which is 2.68, but the heavy mineral chalcopyrite readily float, but quartz settle to the bottom. It has been found that the floatability of minerals is related to the affinity of water. Any mineral that has a high affinity with water and is easily wetted by water is difficult to adhere to bubbles and is difficult to float. Minerals that have low affinity with water and are not easily wetted by water are easy to float. Therefore, it can be said that flotation is a beneficiation method based on the difference in mineral wettability of minerals. The nature of minerals that are easy to float and difficult to float is generally referred to as the floatability of minerals. Flotation is the use of the difference in the floatability of minerals to sort minerals. In the modern flotation process, the application of the flotation agent is particularly important, because after the flotation agent treatment, the floatability of the mineral can be changed, so that the mineral to be floated can selectively adhere to the bubble, thereby achieving the purpose of beneficiation. Flotation is one of the most important methods of mineral processing. According to statistics, 90% of all non-ferrous metal ore processing flotation process. In addition, the flotation method is also widely used for the selection of mineral raw materials such as rare metals, precious metals, ferrous metals, non-metals and coal . In recent years, flotation has been used at home and abroad for water purification and sewage treatment. It can be seen that the application range of the flotation method is quite extensive. Compared with other beneficiation methods, when flotation is used to select fine-grained ore, the effect is better and more economical and reasonable. Flotation is also commonly used to select fine fractions of coarse or coarsely unevenly infiltrated ore. What are the basic operations of the flotation process? Flotation is the same as other mineral processing methods. It is necessary to prepare the materials before the sorting, that is, the ore should be graded by grinding to achieve the concentration fineness suitable for flotation. In addition, there are several basic operations for flotation: 1. Adjustment of pulp and addition of flotation reagents The purpose is to cause the difference in the surface properties of the mineral, that is, to change the wettability of the mineral surface, to adjust the selectivity of the mineral surface, so that some mineral particles can adhere to the gas fullness, while others can not adhere to the air bubbles. Second, stir up and cause a lot of bubbles By means of the aeration stirring action of the flotation machine, the air in the slurry is dispersed to form a large number of bubbles, or the air dissolved in the slurry is formed into a micro-saturated state. Third, the mineralization of bubbles The ore particles selectively attach to the bubbles, which is the most basic behavior in the flotation process. Fourth, the formation and scraping of mineralized foam layer The mineralized bubbles rise from the lower part of the flotation tank to the mineralized surface to form a mineralized and saturated layer, and the useful minerals are enriched into the foam, which is scraped out to become a concentrate (middle mine) product. The non-target minerals remain in the flotation cell for sorting purposes. Generally, the minerals floating in the flotation operation are useful minerals. Such flotation process is called positive flotation. Conversely, if the floating mineral is gangue, it is called reverse flotation (or reverse flotation).

Ancient Greece, people in celebrating the birthday of the goddess of the moon, on the altar placed in a candle and honey cakes. They believe that burning the candle with a mysterious power. If the child make a wish, and blew out all the candles, they can get it.And the candle is also called votive candles.Therefore, this custom spread so far.The custom of inserting candles on the birthday cake dates back to the ancient Greece and Rome. Admirers of the ancient Greek moon goddess Artemis in celebrating the birthday of the goddess of the moon, at the altar put in a burning candle and honey cakes. Later, this custom gradually evolved into children's birthday cake in a burning candle, and increased the content of blow out the candles. The ancient Greeks believed that a burning candle has a secret magical power, if a child has a wish and blew out all the candles, he may wish.Therefore,there are different kinds of candles,including jelly candle,citronella candles.
That flotation froth flotation beneficiation methods is to divide the mineral composition according to different physical and chemical properties of the mineral surfaces.
