Lecture Theatre Fortune Mechanical Flotation Beneficiation Process Major Considerations

The whole process of flotation operation divided into roughing, scavenging and selected three independent but closely linked that the flotation process.



Sorting area, thick foam products are generally sent to the constituency for one or more selected areas rich selection, select the bubble for the final flotation concentrate product. Handle the sweeping electoral scrapings of the ore and selected areas of the tailings product, the flotation process has become critical issues can not be ignored, in control of how much ore flotation operations for the appropriate focus of the whole. line spooler

Amount of control in the mining cycle: a look at the entire flotation process is compared to the amount of pulp flow; foam tank is not open full tank run, liquidity is less foam is not smooth; flotation tank mine slurry scrape pulp bit is high, the second rule of thumb to determine whether the factors from the upper and lower operating and process conditions caused by the change. General control of mineral content of 40-80% return.



Flotation operation, we should diligently observe the color of bubble, foam thickness, and scraped the foam changes the sound, but also to judge good and bad Ore and other processing conditions are controlled an appropriate inspection methods. Jinchuan Nickel Ore during roughing operations is really the main re-watch the bubble, foam layer is thicker, more uniform bubble size is the first slot to the most non tank, the thickness of the bubble there is an obvious color change; bubble blown foam tank is Cha Cha ring, in order to determine indicators of good. If roughing thin foam tank, foam and large number of small landscape, color gloss bubble did not change significantly, flotation tank boil, scrape surface with a slurry of foam has fallen into a Para Acoustic foam tank, flotation were certainly worse.



Constituency and selected areas of the sweep bubble color observation, the main tailings grade and concentrate grade to judge whether the low and high. The last row of foam color is generally the best shallow surface metallic luster, indicating distinct levels of mineral separation; flotation tank dead with a gloss of a bubble, indicating flotation agent and other appropriate adjustment of process conditions, conducive to the tailings lower. Flotation concentrates on domestic goods panning method is hard to determine the high and low grade, can only control the selection of tank foam layer 200_300mm over for good, non-selected operating scraped the pulp into the concentrate product, so there help get products of high grade concentrates.



Flotation aeration rate and liquid slurry gate regulation, control the thickness of the foam tank, flotation work in the current operation there are more key question. In practice, some work good at the inflated amount of flotation and flotation combined gate to regulate the formation of thick liquid slurry bubble layer, but with inflation adjustment King mine blow bubble surface can not be fully floating Flotation machine and process of the election results * inflatable flotation pulp level control gates and gate, with inflation adjustments to be flexible so that the gate, otherwise the operation also brought difficulties to the flotation potential.



Use good aeration and slurry level control gate gate gate with inflatable flotation tank foam balance adjustment is not turned flower, bearing in mind the stirring effect adjustment flotation, flotation machine motor belt of elastic; ore slurry Ore gate to adjust the bubble surface when scraped with no pulp, so that flotation machine with thick foam layer. If the flotation efficiency is not high, should be promptly for inspection or repair and maintain efficient row of flotation, the flotation operation and improve the flotation to create better conditions.
