How to observe the bubble to judge whether the flotation is good or bad (1) The illusion and reality of the bubble. The mineral particles attached to the surface of the bubble are dense and dense, and the foam is solid. The surface of the bubble is less and thin, the foam is imaginary, the ore grade is high, the dosage of the agent is appropriate, the foam is real, the inhibitor is excessive, and the foam is too small when the collector is too small; Leisuwash specializing in manufacture Automatic Car Wash Machine, touchless car wash , Automatic Touchless Car Wash, touchless car wash equipment, robot car wash, smart car wash system, leisuwash 360, leisuwash leibao 360, laserwash 360, leisuwash touchless car wash machine, leisu wash touchless car wash automatic, leisu wash 360 high pressure touchless car wash equipment, robo car wash, touch free car wash, leisuwash 360 touch free car wash, leisuwash 360 price, automatic car wash price, leisuwash in malaysia, no touch automatic car wash machine.

(2) The size and size of the foam, the size of the bubble on the surface of the foam layer, often varies with the nature of the ore, the pharmaceutical system and the area of ​​flotation;
⑶ color, selection scan floating mineral deeper the color, the greater the loss of metal, the deeper the color of the mineral coarse floating selection area, the better the quality of the concentrate;
(4) Gloss. The rough selection of flotation sulfide minerals, the mineralization of the foam in the selected area is good, the metal luster is strong, and the foam mineralization in the sweeping area is poor, showing the glass luster of the water film. If the semi-metallic luster appears in the sweeping foam, the metal loss is large;
(5) Profile, when the foam is mineralized by the medium hydrophobic mineral grain, the water is sufficient, the contour of each bubble is relatively clear, the foam stays on the slurry surface for a long time, the mineral is hydrophobic, and the wall is dry and defective. After that, the bubble outline is blurred;
(6) Thick and thin, the thickness of the foam layer is mainly related to the amount of foaming agent and the degree of bubble mineralization. There are many foaming agents, high ore grade, high concentration, good mineralization, and the foam layer is generally thick, and vice versa. It is relatively thin, and the floating mineral ore is too thick, and it is difficult to form a thick foam layer. The mineral surface of the selected area is low, the foam layer is thick, the concentrate grade is high, the sweeping area keeps the pulp surface high, and the floating mineral can be scraped out in time. Thinner, higher recovery rate;
(7) Brittleness and viscosity, the brittleness of the foam is too large, the stability is poor, it is easy to break, and sometimes it can't be scraped. On the contrary, the foam is too viscous and too stable, which will cause the flotation machine to “run the trough†and destroy the normal flotation process, causing fine mine transport difficulties, excess foaming agents, fall oil or ore slime and a large amount of lead sulfate and other soluble salts, can be excessively stable foam;
(8) Acoustic, the sound of the “sand†is emitted when the foam is scraped into the foam tank by the scraper, and often the foam contains a large amount of minerals with a relatively large specific gravity and a coarse particle size.
Leisuwash 360 touchless car wash machine high intelligent high quality, with car wash + car care + drying process totally, each car wash takes time 1 minute to 5 minutes which depends on the car wash mode.
Automatic Touch Free Car Wash Equipment more and more popular in car wash business market, as can save employee fees and wash time mostly, bring investor much more benefit profit return. That's why choose the automatic car washing system.
